Aeroplane Design

A Fun Project by Paul Hamilton


My wife says I have way too many hobbies. She’s wrong of course. One of the “few” hobbies that I enjoy is building and flying RC airplanes. I am now flying the so called “giant scale” airplanes. My most recent airplane is a 1/3 scale model of an Extra 330 aerobatic airplane. The wing span is 102” and it is powered with a two cylinder 100cc 2 stroke engine.
Prior to the 100cc plane I was flying a 50cc Extra300.


A while back I had the unfortunate experience of disassembling this plane during a fairly hard landing. The landing really wasn’t all that hard, it was just that in the months leading up to this incident I had been making good progress in removing much weight from the airframe in trying to improve its performance. Unfortunately my weight reduction efforts eventually led to some compromises in the integrity of the airframe to the point that… well you know.


I could have purchased a replacement fuselage and had the plane flying again, but I decided to see if I could rebuild it. A friend had the same fuselage that I could use to measure parts, another offered to make the parts for me on his CNC router, so I decided to give it a try.
I spent a few hours measuring parts and sketching them out on paper. I then modeled all of the parts in 3D using CoCreate. As the assembly came together I adjusted the models as needed to get a good fit.

With the 3D models created and fit together, the necessary data was sent to the router to get the parts manufactured.


These parts fit together so well that they actually held together without glue. After spending some time cleaning up the old fuselage, the new assembly was fitted into what was left of the originally fuselage. With some glue and clamps the fuselage was as good as new.
The plane is now in great flying condition and I still enjoy flying it. I think I will just leave the weight alone this time. It is safe to say that had I used my 2D sketches and 2D drawings to manufacture the parts I would have had to correct a few mistakes and even make some of the parts over. With 3D models the parts were perfect, the first time.

Better use a CNC Router

I was telling people that it was over 400 holes, but though the drawers are about 27×22, the actual grid for the pot separators in the bottoms of these drawers is only 16×22.

Still, the enormity of just how many holes I’d set myself up to drill only sunk in after the first hundred. I’d clamped two of these together with a sheet of pegboard on top for stability, and used 1½” of maple block drilled out on the drill press to keep my bit vertical. I put it on a sheet of cheap ply to help reduce tear-out, but if I ever do this again , I’ll not only clamp the bottom layer in too, but I’ll also use a brad point bit.


Better use a CNC Router!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Textured surfaces, the latest trend in furniture design



Delcam, a CADCAM software development specialist, discusses the alternative methods of creating tactile surfaces.

Textured doors and panels are becoming increasingly popular in today’s furniture industry. However, these are relatively simple things to create using any one of the CADCAM (Computer Aided Design & Manufacturing) software packages in Delcam’s ArtCAM range.

One simplistic, yet effective, method using any one of the ArtCAM products: Express, Insignia or Pro, is to use the shapes and sizes of CNC router tools, such as Conical or Ball Nose tools, to create the texture as they carve away the material. This can be done by designing line drawings (also known as vectors) and repeating or mixing them with other designs which will then be used for the router tools to follow (the toolpath).

An alternative method to create extremely eye-catching results is for the designer to choose from a variety of textures available in the ArtCAM Relief Clipart Library, or by importing a photo or image of a texture into the software. ArtCAM is compatible with a wide variety of bitmap file formats.

ArtCAM attributes differing heights to the lights and darks within an image to create a greyscale image, which is then converted into a 3D image/relief. In ArtCAM Express and Insignia, this can then be saved and imported into any ArtCAM model file on which the designer is working.

With ArtCAM Pro, the advanced product in the range, the user has even greater design freedom, as they can then manipulate and work with the 3D texture relief to create their complete 3D model using its patent pending relief layer management system. Additionally, the user can create a multitude of organic textures with its sophisticated modelling and sculpting tools.

For example, using ArtCAM Pro’s ‘Texture Relief’ tool, the user can select from an assortment of shapes that they would like to apply to their relief, such as conical, spherical or weave effects. With the ‘Clone’ tool, the user’s 3D texture relief can be used as a sculpting brush of any size, and then ‘stamped’ on the relief layer wherever the user clicks their mouse or taps their pen on the Wacom tablet. Other sculpting tools can then be used to smudge and smooth the design. Unique shapes that spin, twist and turn can also be easily made with ArtCAM’s intuitive relief tools.

Unlike other packages on the market, all ArtCAM Products offer the user the opportunity to see their design prior to machining. In ArtCAM Pro, the user can view their textured panels with their other models, or furniture components, so that they can see how the textured piece will look in context.

Sealegs extends computerised production with 325 tonne press


A new custom-made 325 tonne capacity computer controlled press has been installed at Sealegs fabrication facility in Albany, Auckland,New Zealand.The new press gives Sealegs the capability to fold up to 7-metre hull plates, in a single operation.The computer controlled accuracy of the press ties in with Sealegs goal of end-to-end computer aided design and fabrication of its amphibious boats. All Sealegs boats are designed and modelled in the 3D CAD package SolidWorks with each hull’s seventy five aluminium parts cut in-house on a 7-metre CNC router.
Sealegs recently announced that efforts to overcome its production backlog have been successful and the company will shortly be in a position to build for stock. The company is actively looking for additional distributors, particularly in Europe and North America, as Sealegs continues with its international expansion plan.

The CNC Milling Process

George Ure Says: CNC milling finds application making a wide range of custom parts. CNC milling is a cutting process in which material is removed from a block metal or plastic by a rotating tool. In CNC milling the cutting tool (called a “mill”) is moved in all three dimensions to cut a desired shape from stock.In this process, the material is usually removed by both the end and the side of the cutting tool. Unlike a drill which removes material only from the end, in CNC milling the cutting tool rotates about an axis that is perpendicular to the table that holds the work. Cutting tools of various profile shapes are available including square, rounded, and angled. A wide variety of part shapes and geometries are possible. The most common are the “end mill” which finishes to a flat bottom surface while a “ball mill” has a rounded end.A wide variety of 2D and 3D shapes are possible in the process. Some of the examples of CNC milling are engine components, custom jigs and mold tooling, complex mechanisms, enclosures, etc.The thing CNC Milling does especially well is create complex shapes block material. While CNC milling can be used on 2D projects, there are lots of other choices for thin stock. Waterjet cutting and plasma cutting, for example, come to mind. But thick stock, needing metal removed? That’s where CNC milling shines. The CNC Milling process proves to be cost effective for short runs.In the event you run into large production quantities, then you might wish to consider cast or forged parts.When you set about designing a new custom part, keep a wide range of cutting machines in mind. Depending upon the production quantity you can model the cost of Laser Cutting, Turret Punch or Fixed punches, and the cast or forge decision.The easy way to get started making custom CNC parts is to design them in free 3D CAD software available from www.emachineshop.com, the world’s first online machine shop. Once a part is draw, it can be assigned to different machines and prices and deliveries compared. If you like your design, eMachineShop is only too happy to build it for you.

Circular saw blade for use with CNC router?


Antony G asked: I own a CNC router and I have been cutting some MDF into strips. I’m currently using a slitting saw blade which is OK but ideally I would want to use a standard circular saw blade because it will cut through the MDF easier.
The trouble is all these circular saw blades are normally advertised for use with either a table saw or a hand-held circular saw. Are these saw blades OK to use with a CNC router?
Basically, what I have done is to bolt the spindle on my CNC router sideways and attached the saw blade using an arbor. Using a slitting saw works fine but I really want to use a circular saw blade instead.
I can’t see any reason why there should be a problem but for safety reasons I just thought i’d better check.

Please comment your opinion.

CAD Design Process - CNC Process

by Ivan Irons :

CAD Design Process
When designing something complex in CAD you will find there is a bit of a process. First you design parts. Then you build the parts into Sub-Assemblies. Next you build sub-assemblies into Groups. Then you build the groups into the machine. It is a logical pyramid process. You can also think of it like a file structure inside of a computer.
Designing Parts
Parts are your building blocks. Without this level, nothing could be produced. The part level breaks the entire “thing” down to its simplest form. You also manufacture at the part level. You make parts, and then assemble them into other things. Parts are generally made out of raw materials.
Think of a differential on the rear axel of a car. The differential is made up of gears and a housing. Each of these are parts of the differential and the differential is the assembly of these parts.
Designing Sub Assemblies
Sub Assemblies are the next level up and I am guessing you are getting the idea. You first design parts, then put them together into sub assemblies. In the car example above the differential is a sub assembly in the axel “Group” of the car. Sub Assemblies are put together to form groups.
Designing Groups
Moving up the design chain, groups are usually things you can identify with. It could be a door, engine, transmission, or cooling package on a car. Above we used the example of an Axle as a Group. Groups are put together into machines. Our example is a car, which is at the machine level.
Designing the Machine
Finally, the top level of all your designing, the machine. The machine could be built for the end user or be sold to another manufacturer. That manufacturer could use your “machine” as a sub assembly or group. You can see all this is just a matter of viewpoint. You can consider just about anything a sub assembly, group or final machine. It is all just semantics and what you are using the item for.

CNC Windows Software

By Paul Disley


The development of computer numeric controlled (CNC) routing, using affordable personal computers has already begun to revolutionise all aspects of the woodworking industry. In so doing it has created new opportunities for large and small businesses as well as for individual craftsmen.
CNC is a technique whereby the movement of a router head is controlled by instructions from a computer. These instructions come from a computer program or list that the user keys into the CNC 860 console or into a computer as ISO standard commands called ‘G’ codes.As an example, the code G01 X100 Y100, instructs the head to move in a straight line to a point horizontally and vertically 100mm away from its starting position.
The CNC 860 The Trend CNC package is based around the Elu/DeWalt CNC 860 Machining Centre, which has a machining area of 860mm x 860mm x 90mm. These dimensions relate to the three axes, X,Y and Z (width, length and height). Each axis is served by a separate stepper motor, controlling the movement of the routing head. Two head options are offered: a modified portable router or a continuously rated, high cycle motor, that provides improved performance for intensive machining applications.
Programming directly in G-codes through the console can be time consuming. To assist the operator, a PC software application called CNCTalk is included with the machine. This is a basic computer aided design (CAD) application which runs under DOS, the original PC operating system before Windows. It is useful for intermediate applications like cutting out irregular shapes. However, to gain the maximum versatility from the CNC 860,Trend’s Open Sign System Software for Windows is the most effective solution.
OSS consists of two separate software applications: OSS Draw which provides the drawing tools to create any shape or sign, and OSS Work which handles all the routing and tooling-related parameters like depth and offset. Graphical simulations are shown for all tool parameters enabling the user to perfect a design before routing any material.
Sign-writing As an example of how these products work together, the method of producing a simple sign is shown, incorporating two different lettering styles and a graphical logo. Having launched OSS Draw, the first step is to draw a box or boarder on the screen to indicate the overall area of the work. This can be either a simple rectangular boarder or a more decorative one. This border then needs to have a depth assigned to it. This is done by using colours to define the depth of each area.
The logo is then created using the drawing tools within OSS Draw. The words are keyed in using the text function. Again, colours are assigned to each area to produce a graphical representation of how the finished sign will look. The next task is to define the routing parameters. In the example, the red and blue areas of the logo and the lettering have been assigned a depth of 5mm and the green area assigned a depth of zero. The same dialogue box lets you specify whether a letter or object is engraved or routed through the material. The cutter profile that will be used can now be defined. With lettering, particularly serifed fonts, the cutter used needs to have a small diameter, perhaps 3mm. However, to achieve a 5mm cutting depth this will have to be routed in several passes.
A simulation of the cutting path is now drawn on screen. Having then created a G-code file of the sign ready for the CNC 860 to cut, the file is downloaded to the CNC 860. The design can now be routed, the material being held on the bed by an adaptable clamping mechanism. From the simulation, the path that the tool will take is known allowing a datum point to be set using the zero key on the console, and the program 8 INProfile is run using the start key. This type of routing operation takes around 20 minutes to complete and requires no further involvement by the machine operator. Other accessories Sign-writing is just one of the many complex and wide ranging routing operations that can be carried out using the OSS and CNC 860 package. OSS also has a range of tools for drawing component shapes and profiles directly or with an electronic sketchpad (graphics tablet). Vacuum Clamping To reduce the through-put time for this kind of operation, the CNC 860 can also be used with a vacuum bed. Trend offer a complete range of affordable vacuum pumps and jigmaking accessories to enable all CNC users to produce a highly automated production system to suit their own specific requirements.

CNC Process Overview

Ivan Irons told:

This is how I view CNC. I break it down into simple steps that I can remember. Now, they all interact, but it is good to keep them in boxes for simplicity sake. I also like to keep them in a logical, progression type order. Here they are: Design, CAD, CAM, Control and Machine.
Today you are going on a journey. You are going to learn about the basics of CNC. I hope you are as excited as I am about this topic.
I have been using CNC equipment in my home shop for six years now. The technology gets better and better every year.
The software gets better every year. At one time large companies could only afford this technology. Now there are hundreds of thousands of these machines working in garages like yours and mine.
There are basically five elements to a CNC Project that you need to know:
Design - thinking and planning what you want to buildCAD - translating it into the computerCAM - converting it into machine languageControlling - directing your machine’s motionMachining - building the part to specifications
These five elements are really the building blocks to a CNC project. As you see them above, that is generally the order people associate them in. For example, you can’t control until you have a design. You can’t use your CAM software before your CAD software. One of the main things you need to address is how these elements interact with each other.
Right now this may seem confusing. Over time, it will seem very basic. The more you use these elements with one another, the more their order will become second nature.
Note: The A-axis is the rotational axis. Why is it called that? I don’t know. It is also sometimes called the B-axis. I have even heard it called the W-axis. A-axis is the rotational axis around the X-axis. B-axis is the rotational axis around the Y-axis.
Buying a completed CNC Machine
If you purchase a CNC machine outright, it will have a machine controller as part of the package. Everyone does it a bit different though. Some try to make it a black box that only they can fix. Other use commonly used components so you could repair it if need be. You will just have to ask the manufacturer and see what they say. My experience says they usually tell you that it uses common components that you can get anywhere if needed. If something goes wrong, it seems you can only get the part from them. You will have to decide.
Internal Machine Controller Parts
There are many different electrical components that go into a machine controller. I won’t pretend that I am an expert on this. Actually, this is one of the components I buy pre-made so I don’t have to do it. If you are an electronics junkie you could build your own. I know where my skills are at and it isn’t in assembling and understanding electronics.
Here is what I know about the guts of a controller. There will be drivers. One for each axis.

An Eliptical Rocker by Erik



He got hooked on designing flatpack furniture and this rocker came out of it all. so far everyone seems to like it and its really stable. Erik tried to roll it over backwards, but because of the elipse, he just couldn’t do it. His grand kids even gave a go and it did pretty well.

CNC Lathe And Wood Lathe Useful Informations

A CNC lathe is a machine that can spins material to do a variety of operations like sanding, drilling, cutting or sanding. Usually a lathe is used for more intricate cuts and Today, they replace the older multispindle lathes because they are easier to set up and operate.
Each CNC lathe has a computer control that allows the machine to be controlled electronically, and this program can be modified to do a variety of things. When an operator runs a CNC lathe they have to have a lot of skill to understand the programs and how the programs to do the work.
The point of using a CNC lathe is to make a piece of material that is symmetrical and beautiful. This is done by placing the material in a machine and allowing that piece to be spun until it reaches the specification that was programmed into the computer. The cutting tools then move around it on the Z and X axis to cut away the material that isn’t needed to make the piece.
The process that the CNC lathe does is called turning and it can do a variety of shapes when it goes through the full process. Many machines are used to create a plain surface to make contour shapes, to taper the ends of some pieces and it makes threaded surfaces. You can also turn metal so that you can create rods bushes, pulleys or other shapes that are needed. In some industries they use a CNC lathe to fabricate parts that may have a cross section that is to move in a circular motion.
Mini lathes usually come in three sizes: 7×10, 7×12 and 7×14. Each one is measured by the length that length of the swing as it goes over the bed of the lathe. Today you can also find 9x models. The conversion of a general mini-lathe to include CNC has many benefits.
When converting to CNC it will generally take one or two weekends to finish the conversion; however plans will vary depending on what you want your CNC mini-lathe to do. You can usually buy plans that include pictures and step-by-step directions for around $50.
Are you in the market for a CNC (Computer Numerated Control) machine? CNCs are very useful for industrial work and woodworking shops. They really aren’t beneficial for the weekend do-it-yourselfer but if you would like increased speed and accuracy on large jobs with repetitive tasks then you should consider purchasing a CNC machine. Here are some tips to determine the right one for you and your budget. First off, it’s important to know what a CNC machine does and how it operates. It is a machine that performs tasks using woodworking tools. It must be programmed properly before operation and once the initial set up is done, it will do exactly what you’ve programmed. Therefore, if you have a repetitive task then the CNC machine will ensure accuracy and uniformity. For example, a CNC router can be programmed to drill holes in a designated fashion. The results will be more uniform and accurate than drilling manually and you won’t become tired of operating a manual drill.
There is also CNC engraving equipment which is used for engraving a variety of materials and are more accurate that any manual engraving could be. They are widely used for signage lettering for both large and small projects.
Not as inexpensive, but still a savings and more reliable is a refurbished CNC machine. The machine is reconstructed by the manufacturer and worn parts are replaced. They often come with a warranty so it offers some consumer safety.

What is CNC Controlling

Since we are dealing with machines that do work for us, we need to control those machines somehow. We need to control them for safety reasons as well. If you give a machine improper commands it can easily get out of control and cause harm to you or the part you are machining. We want to give good commands to our CNC machines, at the right times so they are not “out of control”.
The language that these machines use is called GCode G-code has been around since the early 60’s. There are a number of variations of G-code, but most are very similar to one another. See the previous section for a sample of G-Code.
We need a computer to interact with our CNC Router. Our computer will send signals to our CNC machine. In-between our computer and our CNC machine sits a controller. A controller converts commands into signals that are used to control the motion of our machine.
As these signals are sent out of the controller, they go to either stepper or servo motors. This is how we create motion. These cnc motors drive our various axis on our machine. While we are moving our axis, there is generally a cutting tool of some sort removing material. This is the machining process coupled with CNC.
Here is a brief description of the two types of motors generally used in CNC:Stepper motors:Simple designEasyGenerate torque at low rpmDo not know their position in relation to the program
Servo Motors:Generate torque at high RPMsGenerally need gearing of some sort to be effectiveMore sophisticatedCan maintain their relative position, thus, they can be more accurate
CNC Machine ControlsControllers generally stand alone near the CNC machine. They act as a translator between your cnc control computer and your machine. Generally, they add quite a bit of cost to a CNC machine as well. Controllers can cost anywhere from $1000-$20,000 or more depending on their sophistication.

Suction systems of CNC router

Suction Systems
The wood router typically holds wood with suction through the table or pods that raise the work above the table. This type of hold-down is used for components which require edge profiling (or undercutting), are manufactured from solid wood or where greater flexibility in production is required. This type of bed requires less extraction with greater absolute vacuum.
A second type hold down requires a “spoil board” or “cull sheets” to the work. This allows vacuum suction through the low density table and allows the placement of parts anywhere on the table. These types of tables are typically used for nest-based manufacture (NBM) where multiple components are routed from a single sheet. This type of manufacturing precludes edge drilling or undercut edge work on components. However most industrial sized machines similar to the S series CNC by Vortech Routers or C.R. Onsrud Panel Pro allows the use of spoil boards or a pod system that elevates the work piece to accommodate edge work.
Vacuum pumps are required with both types of tables where volume and “strength” are determined based on the types of materials being cut.
Redsail M series CNC router has such a function which will fits many customer’s requirements.
At the same time, our CNC wood router also has Oil lubrication system which can smooth the rail and block for rail.

Cutting Aluminium in CNC Router

Hello,

I've been experimenting with cutting Aluminium on my mdf router and have broken quite a few bits when cutting at lower rpm, and I don't understand why?

What tends to happen especially if the feed rate is too high and coolant/lubrication is inadequate is that chips get packed into the flutes then you get a mess because they rub, melt and the cutter breaks.Always use two flute if possible to get better chip clearance. Keep the chipload below 0.0005" per tooth (0.01mm). With carbide you should be able to go at full rpm because the surface feet per minute is just over 600; carbide can cut aluminum at 3 times that. At 20000rpm your feed will be not more than 400mm/min.But really the most important thing is adequate lubrication. You could try automatic transmission fluid (ATF) it works very well. Brush it on ahead of where the cut will be. Kerosene works well but is more of a fire hazard. Or see if your local Shell petrol station has ever heard of Shell Dromus B. This is a cutting fluid made by Shell for the last 80 or a 100 years ro so. It is mixed with water normally but works very well just brushed on neat.

Ok, my depth of cut is 0.3mm and my feedrate is 450-600mm per minute. (That's 0.012" and ~24ipm, I think.)

I think your depth of cut maybe slightly to much for such a small bit. If it was a 4 flute end mill, maybe. I also think your feed may be a bit fast.

Atlas Signs and Plaques announces Custom CNC Router Services



Atlas Signs and Plaques, and parent company Metal Facades, announce Custom CNC Router Services at their Lake Mills Wisconsin studio and shop.



The CNC routing capabilities at Metal Facades can accommodate work five by ten feet and up to six inches thick. HDU, plywood, plastics, hardwood, sign material, acrylics, and fiberglass are some of the materials that can be accommodated. Full cutting and routing is available to most any non-ferrous metal including aluminum. With no job too big or too small, and upfront pricing, the accuracy of CNC table milling is now available to boat builders, hobbyists, aircraft restorers, museums, exhibit manufacturers, custom woodworkers, cabinet shops, and others who thought the cost of custom CNC routing was prohibited. When asked about what uses clients might find for her machinery, Owner Janey Freid said. “In addition to signage, we currently do custom artisan work on architectural elements, historic recreations, museum pieces, tradeshow exhibits, and much more. Our new router allows us to shape larger pieces and mill surfaces for large tabletops and counters. We have always specialized in the unusual. And now, having the machinery, software, and knowledge to do 3D routing increases the scope of work that we make available to our clients.”

“We are not really a full-service sign shop,” added Ms Freid “We have been more of an artistic custom metal coating applicator with great design ideas, specializing in unusual projects. As an example, we just completed a large project for the new U.S. Capitol Visitor Center in Washington D.C., transforming two 17 x 23 foot frames made from sign foam into bronze, and saving our clients dollars and weight. Recently however, Atlas Signs and Plaques developed an e-commerce website to provide easy online ordering and upfront pricing on custom metal coated signs and plaques for business, home, garden, and gifts. So we do create products that could be referred to as signs.”

Both Atlas Signs and Plaques and Metal Facades are considered “artistic job shops” and have a steady stream of work pouring in to the studio from an ever-changing client base. “Custom work is what we do.” added Ms Freid. “So it is not surprising that we expand, upgrade and utilize our capabilities to the utmost.”

A CNC Router Installation

This is the CNC machine, which cuts pretty much all our kitchen cabinet boxes, as well as a bunch of other stuff (signs, curved arches, panel doors, etc.) .Above the CNC, on the racks are two large grey vacuum pumps. There are for the suction on the CNC table, which keeps the sheets of melamine (or whatever you're using) from moving around while the pieces are being cut. It's basically a giant computer operated router. You can see a cutout from a custom curved casing (window molding). We cut the blanks on here, then pass them through the molding machine.

A Graphic Inlay

He still does website and graphics work for them and the photos below show one of his recent collaborative projects. He and Trevor took a hand drawn graphic and created files that could be used on our CNC router to create this inlay design of Peruvian walnut in natural cherry. There are a lot of pieces but all the pieces fit great. The VewDo people have some ideas how they are going to use this piece and I can't wait to see the finished products. I think it's a great concept ....The walnut inlay pieces and Trevor's first sample test inlay in mdf and fibrexThe finished, sanded inlayImagine it up high like a sign ....



Shopbot router tool bit holder




Today I built a really simple holder for my shopbot bits and collets. And here are the source files I used to build it: bit-holder.zip. It includes the sketchup model, .dxf, PartWorks V2 .crv file that generated the toolpath, and the .sbp shopbot partfile itself.It's astounding how bad this workflow is. There are plenty of opportunities to make mistakes with each of the 4 different file formats, and every time I make a change to the sketchup file, I have to manually regenerate each of the following steps and try to remember what settings I used. Plus, each of the 3 programs has bugs that create headaches at best and dangerous situations and ruined parts during manufacturing at worst.So the bugs need to get fixed regardless. Then there are two ways to make the process better: make the workflow shorter, so that at least there's a single UI for each of the steps, or make the tools more modular and configurable so that you can automate the process of stringing them together. The former approach reminds me of "integrated development environments" for writing software, such as Microsoft's Visual Studio. Everything comes with a slick user interface, and debugging, compiling and project management are all built in. The downside is that you're stuck with that package of tools, and automating big tasks like rebuilding a huge software product don't usually work very well.The latter approach reminds me of using Makefiles to build software. You have to do some work up front to define how the parts of your project get built. But once you've done that correctly, typing "make" is sufficient to automatically rebuild any parts of the project that have changed. Big software projects almost always use this approach, in my experience.The latter approach is the one I'd prefer in this case. There are three distinct parts to manufacturing a part on a CNC machine like this: making the 3d model, defining the toolpaths (what type of cutting bit to use, what what type of cut to make, feed rates, etc.), and executing that toolpath on your particular machine. Each of those can be relatively independent and should be interchangeable. And ideally, they'd all be available as Free software.So someday, I'd like to be able to build my part in Free Sketchup, look at the Free toolpath generator's idea of how to cut it, tweak a settings file to fix anything I don't like, and then do a quick check on my Shopbot Simulator to make sure it'll cut the way I expect. And then when I have to tweak some part of the model, I can just run "make" and get all the derivative files generated automatically.

Success In Engraving ID Products, Nameplates and Signage

PurposeConventional engraving for signage can be performed by any one of four basic methods – all of which result in the removal of material from the surface of a workpiece. This outlines each of the three engraving methods, common materials and the technology available for increasing efficiency and quality of the end product. Four Types of Equipment:The pantograph is a manually operated machine that removes material using a rotating tool or diamond scribe. The tool is connected by levers to a stylus that is moved manually by the operator. The operator uses the stylus to trace a template of each letter. Because the tool follows the motion of the stylus, each letter must be precisely positioned to reflect the actual layout of the work. While pantographs are still used widely to engrave small plates at shopping mall stores like Things Remembered, they are generally considered an inefficient and outdated technology for industrial or 3D engraving. This is because the process requires and operator who is tied to the machine for the duration of the process. Not only is this costly in terms of labor, but the quality of the end product is dependant upon the skill and experience of an individual operator and may vary from shift to shift or part to part. Skilled pantograph operators are truly craftsmen of a dying art form. As a result, it is becoming increasingly hard for manufacturers to find qualified operators – and what they may save on the cost of equipment is usually offset by the cost of labor. Additionally, since the process is extremely taxing from a physical and ergonomic standpoint, employers are vulnerable to the added costs of workman’s compensation or disability.So, most engraving today is done with CNC (Computer Numeric Control) engravers and routers. The CNC engraver uses a rotating tool to remove material. The engraving is designed on computer software, converted to numeric commands for each axis of motion. These commands are sent to the machine and the spindle that spins the tool is moved by stepper motors or servo motors. While quality and repeatability are clear advantages for CNC routers, the process can also be performed by an unattended machine which lowers the cost of labor. Additionally, some CNC routers are multi-tasking industrial workhorses capable of engraving, milling, cutting, tapping and routing at a single work cell – throughout a 24/7/365 production schedule. This provides manufacturers with the flexibility to produce more complex engraved parts, the efficiency to increase throughput and the agility to take on new multi-phase projects.Laser engravers are a type of CNC machine that use a focused laser beam, instead of a rotating tool, to remove material. While lasers rival CNC routers in terms of speed and quality, the type of cut that they produce generally doesn’t appear “authentic”. That’s because lasers don’t penetrate the workpiece as deep as rotary engraving and it lacks the look and feel of traditional engraving. Another drawback of laser engravers is that they often require special types of engraving material – so the substrates available as “blanks” are limited in color and texture and are more costly than those available for rotary CNC engraving. Finally, there is stamping. With this process, a die is made for use with the stamping machine. Each die costs in the range of $2,000 to $3,000. For high volume production, say 20,000 parts, stamping is a logical choice because the stamping machine can produce a couple parts per second. But, for low volumes the cost of the dies cannot be justified. Another down side to this process is that the edge quality is far inferior to parts made on a CNC router. This is because the stamping machine removes material from the workpiece by pushing the die down through the material like a cookie cutter. The force created at the location of the cut bends and shears the substrate. With malleable materials like metal this can mean bending at the edge and with other more brittle substrates, chipped edges can result. Finally, unlike the multi-purpose CNC routers mentioned above, the stamping machines are limited to stamping. So if the end product requires a counter sunk hole or tapping, this would require another piece of equipment and a secondary operation – both at additional cost to the manufacturer.Types of Material:Engravers use a variety of mediums to produce signs and nameplates. While some engraving is done in more exotic materials like Dupont Corian (a synthetic resin stone), most engravers use brass, aluminum, and layered plastics.MetalsSolid brass and aluminum plates come in a variety of colored lacquers. Typically, these plates are very thin (about .025”) enabling the engraver to cut and size them for mounting on a plaque board or placing in a frame. Engraving in brass is usually done by removing the lacquered coating with a rotating tool in order to expose the shiny metal surface underneath. This process is called burnishing. Unlike deep engraving, which removes a considerable amount of metal, burnishing barely penetrates the surface of the material. Deep engraving (or milling) of metal is used primarily to make industrial molds and name plates.WoodWood and is other common material used by engravers. Wood is a good material for rotary engraving, though it typically involves more processing time. That’s because after the image or text is cut, the engraved recesses often need to be stained or filled with paint to enhance legibility.PlasticsLike brass and aluminum, engraving plastic is produced in thin sheets (typically 1/16” and 1/32” thick) which can be cut and trimmed to size, then mounted on a plaque board or placed in a decorative frame. The material is layered in a two-color sandwich usually composed of Acrylic or ABS. A rotary tool is used to remove the colored surface material to a depth of .003”-.015”. This exposes the core that contains the second color. Of all the materials available to an engraver, these co-extruded and micro-surfaced resins offer the greatest selection of color, texture, and finish. While some tend think of plastics as cheap looking plastic nameplates, new high tech, co-extruded and micro-surfaced resins can produce quality end products. Unlike lacquered metal, this new generation of engraving material is scratch resistant, it does not oxidize, some of it is durable enough to mount outdoors, and it comes in variety of finishes that effectively simulate stone and metal.Features That Provide The Competitive Edge:High-Speed SpindleMost ID product and nameplate engraving is done with small engraving bits and endmills. These small tools must be run at high speeds. High-speed CNC engraving machines featuring 60,000 RPM spindles effectively evacuate chips from the cutting channel resulting in smooth surfaces and burr-free edges. This eliminates the need for the secondary de-burring operation, as well as the costs associated with it. The 60,000 RPM spindle is designed specifically for engraving and milling with small tools. Unlike conventional CNC spindles designed to run large tools, high frequency (high speed) spindles have smaller motors and produce less force. This helps to maximize tool life by minimizing the force that leads to tool breakage. Conventional CNC machines would have to be run at very low speeds in order to prevent the force of the spindle from breaking these small tools. As a result, cycle times are long and surface finish is inadequate for most engraving applications.ProbingProbing saves time during job setup and ensures accuracy and repeatability. Probes available as an integrated component on some rotary CNC engravers can recognize irregular work-piece topography and compensates for it dynamically. They do this by taking measurements along the surface of a blank and feeding that data into the machining controller. The controller automatically adjusts for uneven surfaces or work piece position. Through this process, job setup times are reduced and piece/part rejection is minimized. With a 3D extension, the probe locates parts and material irregularities in the X, Y, and Z co-ordinates, finds centers of holes and bosses, pre-measures blanks before the machining starts, compensates for material variations, feeds data into ISO 9000 information chain for quality control, and even allows for the reverse engineering of many parts.Oil-Free CoolantWhile Probing can save valuable time at the front end of production, during set up, oil-free coolants like ethanol can save time at the back end. That’s because unlike oil leaves a residue on the completed product, ethanol simply evaporates. So, the secondary de-greasing operation can be eliminated – thereby reducing the cost of labor, the cost of consumables required for cleaning and, most importantly, minimizing total production time. Ethanol is a form of alcohol that results naturally through the sugar fermentation process and is environmentally friendly. It also happens to be an ideal coolant for high-speed, micro machining because a thinner-than-water viscosity allows the ethanol to quickly cover and cool more surface area on fast-moving micro tooling. The low evaporation point of ethanol makes it an efficient cooling solution and also eliminates the need for disposal and recycling, as well as their associated costs.Note: Ethanol coolant should only be used for machining of non-ferrous materials and manufacturers can switch over to oil coolant when machining or engraving steel-based materials.Integrated WorkholdingWorkholding for nameplate applications, like production runs of Metalphoto, can be problematic. Thin substrates are difficult to hold. This is particularly true if the manufacturer is using a conventional CNC to engrave or cut small parts with limited surface area, because the force of the spindle can literally “fling” the part across the machine bed once it is completely cut out. Many manufacturers actually resort to spray glue as a method of workholding. Not only is this messy, it can also lead to bending when the finished part is removed from the machine bed, it sometimes doesn’t hold the part when it is completely cut out … and it results in a time consuming and costly secondary application to remove the glue form the completed parts.Therefore, high-speed CNC engravers and routers are the logical choice for ID Product and Nameplate manufacturers. As mentioned above, these machines are designed exclusively for running small tools and inherently have smaller motors that produce less force. This low force enables innovative workholding technology. For example, some CNC manufacturers have developed vacuum tables that are integrated with the machine bed. So, thin stock, which could be secured only with great difficulties before, is now secured literally within seconds. Plastic foils as thin as 0.001”, to 0.250” large aluminum sheets are secured quickly and held in place even when the parts are “cookie-cut” completely through the material. A vacuum pump provides vacuum power for the system to work. A vacuum table features airflow-optimized vacuum ports, with recessed vacuum chambers, to provide superior vacuum distribution. A low cost gas-permeable substrate serves as a sacrificial vacuum diffuser, allowing the cutter to machine through the workpiece, without cutting into the table.Automatic Tool ManagementID Product and Nameplate manufacturers considering various CNC machines for milling and engraving, need to consider their current processes and what their ideal process might be. In other words, they may currently be running only one or two shifts, but in a perfect world, an unattended overnight shift could be the secret to increased profitability. Even if a “lights-out” shift just isn’t in the cards, a day shift where the CNC machine can run unattended allows the operator to tend to other business – thereby providing the manufacturer with more productivity from a single employee. So, choosing a CNC with the right kind of tool management is crucial.In the world of machining with large tools, monitoring spindle load can be used as a means of detecting breakage. If there is a fluctuation or drop-off in the current, then the operator knows that the tool might be broken. Unfortunately, the benefits of this “Tool Detection” process are limited because it is used only as a means of checking tools and reporting possible breakage without systematically replacing the broken tool. So, the best that a manufacturer can hope for is that the machine will shut off and prevent additional damage to costly blanks. Still, production time is lost — and if the tool breakage occurs early in a “lights-out” overnight shift, it can significantly impact schedules and revenue. Furthermore, this method doesn’t work when using micro tooling because the load involved is sometimes so small that the fluctuation in power usage doesn’t even register.CNCs with an Automatic Tool Management System are a better solution. The Automatic Tool Management System is made up of three separate components working in synergistically — the tool checker, the tool changer, and the software. The tool checker is a mechanical sensor that measures tool length and detects the broken tool. The tool changer is a rack or tray that has space for spare tools and sockets where the machine places broken tools before picking up a replacement. Operators can stock the rack with spare tools, thereby having a ready supply should tools break during “lights out” operation. The software is a macro program that can be set up to run a tool check after executing a number of lines of code. For example, a tool check macro can initiate a check after every 500 lines of code by employing an “if/then” statement such as, “Measure this tool; if the length is shorter than the parameter (listed in the software’s tool database), then change the tool.”Wrapping It Up:ID Product, Nameplate and Signage Manufactures who specialize in low production runs can gain efficiency, flexibility and an overall reduction in cost by using rotary-type CNC engravers and routers. Since most of these manufacturers use small tools, it is imperative that they select a CNC machine designed specifically for use with small tools. High-speed spindles are best suited for small tools and produce burr-free parts with superior surface and edge finishes. The low force of these spindles maximizes tool life and enables innovative workholding that speeds setup time, improves efficiency and makes secondary operations like de-greasing obsolete. Probing also makes setup more efficient and ensures accuracy and repeatability. Automatic Tool Management provides a reduction in cost by enabling unattended or lights-out production. CNC machines that deliver all of these features, working synergistically, provide manufacturers of ID Products, Nameplates and signage with a means to revolutionize their business.

What to Look For in a CNC Manufacturer

A CNC manufacturer is your ultimate source of an efficient CNC machine. If you want to benefit from the best make sure that you find a good manufacturer.
Most of the manufacturing companies are busy employing CNC or compute numerical control technology in their production processes for enhanced effect. The integration of CNC in a production unit is a great way to enhance the flexibility and performance of CAD or computer aided design and CAM (computer aided manufacturing) chain. Hence, there is also a greater effect on the competitive levels of such companies.
When compared, the hardware capacities of CNC systems have significantly improved in the last few decades. This is not all. The software elements have also been upgraded effectively in order to facilitate the enhancement seen on the latest line of CNC machines.
The passive approach adopted by most of the CNC manufacturers, these days has resulted in a lot of incompatibilities among varied CAM, CAD and CAM solutions available in the industry for the customers.
Hence, it is very important to opt for a machine coming from a CNC manufacturer that abide by all the industry standards and believe in providing the latest that's available under the category of these machines.
Here are some of the considerations you need to keep in mind when deciding on a CNC manufacturer to purchase the best machine available for the job:
• Quality: The quality of a CNC machine is of utmost importance. Make sure that the CNC manufacturer put in all possible efforts to make sure that the machine is delivered to a client in impeccable condition. There should be a sure shot guarantee for quality. The CNC manufacturer needs to follow all the quality control regulations set by the industry and keeps up to national and global standards. You need to check out that the manufacturing materials are tested to perfection and exactly match industry standards. The process of manufacture must also take place under strict and expert supervision of experienced technicians. The finished products need to go through an analysis phase to detect any existing faults.
• Infrastructure: The infrastructure of a CNC making machines speaks volumes about the quality of the machine. The infrastructure should incorporate experienced technicians, many workers and finest of machinery. The warehouse of the CNC manufacturing company should be efficacious enough to store a huge amount of products according to the requirements of the clients.
• Clientele: The clientele a CNC manufacturer holds will also tell you a lot about the quality of machine he sells to the customers. You must ask for some of their existing and valued clients. If possible, you need to ask for some references. This will provide you an idea of people's review about the CNC machines.
Following and keeping mind all the tips mentioned above will let you find out a CNC manufacturer who provides the best and most efficient machines for your business.

CNC Machines

If you need a machine that will improve your speed and accuracy then try a CNC machine when you are getting large jobs done or doing very repetitive tasks. You can get a used one for half the cost of a new one since most individuals wouldn’t want to spend their money on a new one. CNC equipment can be found in woodworking shops or industrial settings. Add them to your collection that includes a milling machine as well.
If you need to drill holes than consider a CNC router. Some of them can hold more than one tool too. This makes it possible to do more than one procedure at a time. This will help you cut back on the tie you spend working and help you become more accurate.
Computer Numerated Control is the full name for CNC. In the 1970’s this technology was first created. These machines are easy to run and operate after they have been initially set up. They also need to be set up correctly and programmed before they are operated.
They can be made so you can drill a hole automatically. This can be much more accurate and quicker than manual drilling. You will get more uniform results. If you have a large job that needs a lot of drilling then this can be a good choice for you. You might get more inconsistent results when you are doing manual drilling and if the operator gets tired.
If you want a good thing to cut wood with then try a CNC lathe. You can buy one that ranges from 15-40 horsepower. You will choose the lathe power you need depending on the type of wood you use. You can get a model that comes with more than one mode. You can one that is totally manual or CNC. You can rig each machine for your individual project.
If you want the best in milling technology then try a Bridgeport mill. You can find a mill in both a small shop or a large one. If you want a mill that will last forever than try a Bridgeport mill. They are very pricey and more so than most people can afford.
A CNC mill use a special type of instrument that uses a combination of robotics and computer programming. You will get great results better than anyone could ever want. These are the kind of mills that the airline companies use. The CNC decides which tool is need for an operation and changes as it goes.
Since CNC equipment is so pricey it means most people can’t afford it. If you get a used machine you may find that you can afford it. You may be able to save about half on a used machine compared to a new one.

some formica airfoil templates cut out on my CNC router, let me know. Generally need a vector pdf or dxf file to cut.

CNC in School


For many years I have been wanting to get a CNC (Computer Numeric Control) machine in my classroom. CNC is the industry standard in manufacturing, so it frustrated me that I could not show my students what they would be using in the "real world".

This fall (with much encouragement from my students) I order the CNC Shark Routing System from Rockler. This package came with VCarve Pro 3.1 which is a very simple CAM (Computer Aided Manufacturing) program by Vectric.

We have used this CNC router to create various 2D projects so far, but I am looking to incorporate it into more of my curriculum for next year. Vectric also has a program called Cut 3D that will allow you to take a 3D model and machine it on 1-4 sides of the material. I will be purchasing this next year to expand the possibilities.

This is why I am the Shop Geek. I love creating with Technology! The more hands on, the better.

Barcalounger Implements NESTERwood to Support Its Transition to In-House Frame Production

Moving frame-production in-house, Barcalounger can now better control their production with the deployment of NESTERwood Barcalounger successfully implements NESTERwood, driving better control of frame costs & design and reduced WIP through the production line.

High Point, NC (PRWEB) March 26, 2009 -- Barcalounger of Rocky Mount, NC, successfully implements NESTERwood, driving better control of frame costs & design and reduced WIP through the production line.

"With NESTERwood's easy deployment and easy to operate user interface, we were able to start programming in just a short while," said Richard Henkel, Vice President of operations at Barcalounger. "It was exciting to see our new CNC router working and cutting frames shortly after the installation. We were up and running sample production in a couple of days."

NESTERwood enables upholstery manufacturers to automate and optimize their frame production by generating a solution for nesting and cut path. NESTERwood's Rolling Nest automatically optimizes the placement of pieces from one or more orders on multiple sheets of plywood, resulting in material yields that are consistently higher than any other solution. By generating efficient tool paths, NESTERwood improves the productivity of CNC routers.

"Previously we purchased our frames and had no control over their quality, delivery date or cost," adds Henkel. "With NESTERwood's automatic nesting and programming capabilities we were able to bring our frame production in-house, and gain control over our own production. The material savings and reduced WIP enabled by NESTERwood helped us to justify the transition to in-house production."

"With the enhanced productivity and cost savings driven by NESTERwood, the change to in-house production at Barcalounger was straightforward and reassuring for management who gained more control over their products," says Avner Ben-Bassat, Plataine's President. "It is very satisfying to see how NESTERwood contributed to the establishment of a new frame plant at Barcalounger which is already up and running."

About Barcalounger:
Based in North Carolina, Barcalounger is known for highly valued recliners and motion living room groups designed for comfort, quality, and fashion. The company was founded in 1940 when Edward Joel Barcolo acquired a license to manufacture "scientifically articulated" motion chairs patented by Dr. Anton Lorenz and since then innovation has been a hallmark of the Barcalounger brand.

CNC Router Buying Guide and CNC Router Tips For Purchase

When you are looking for a CNC router there are many things to take into consideration before you buy it. There are many manufacturers who have what you need and you can get a good bargain if you do some research ahead of time.
Here are some things to think about as you are deciding what type of machine you want to buy:
- Do some research -- before you start looking for a CNC Router it is a good idea to do research on all the different types of routers available. If you already have used one, then you know what they can do.
- Decide what you need -- from the research you do you will know the types of projects you want to do and what different machines will do. Look for the specific CNC routers that will cover what you want to do.
- Decide on your budget -- if you have to stick within a budget be clear about how much you will spend so that you can be sure to get a router with the amount of features you need for the price you can afford.
- Buy what you need -- you will find a lot of CNC routers that have bells and whistles on them that you will probably never use. There are also machines that don't have enough for you, so a rule of thumb is to buy what you need with a little upgrade to make sure you get the performance you want.
- Reliability -- you will want to know that the machine you buy will be reliable with larger work loads if you need them. You will also want to be sure that it can handle the load that you use.
- Durability -- check the materials in the main parts of your router to make sure that they can make intricate cuts or carvings and that it can withstand a lot of use. This will really depend on the materials it is made from.
- Know the Software -- you will have some sort of software, usually CAD to understand so that you will know how to make the machine function properly. Sometimes vendors will offer training on this and if so, it's a good idea to take it.
- Create a space -- sometimes people go out to purchase a machine and they find that it is too big for the space they have. This is an important component of buying a CNC router so make sure your router will fit in the space you have and that the floor you have it on can withstand the weight, if the machine is a large one.
Beyond these tips it is important to shop around. If you are willing to do a little footwork you can go where you may be able to try out the machines. Although some people may have used machines it would be better to buy it new so you know its status. Also buying straight from the manufacturer would be better in some cases than buying from the distributor.
