CNC Router cutting of three-dimensional characters using TYPE3)

First, the production process: 1, enter text (point A, to enter text mode. Attention to change the font). 2, the provisions of the word size (select the word, drag the small box around the word, when the mouse into a two-way arrow, press the F2 key, the "scaling" release the left mouse button after the dialog box, type size, pay attention to proportionality). 3, will be transformed into curves of the word after the deformation tool, click the "vertical mirror" to the word in turn. (This step is called mirroring) 4, layout, taking into account at the same time-saving materials to ensure that the stroke is greater than the distance between the cutting tool. 5, according to the text of the order of selection (of the order and selection of cutting the order of the) 6, into the CAM module to calculate the tool path.

II. Cutting Note: 1, the material if the plexiglass into the CAM module to calculate the tool path simulation if there is no problem, you can save the operation. 2, material for PVC, and if the Chevron board, cutting the time to reverse Reverse approach: Into the CAM module, the first tool path calculation (double-click the two-dimensional cutting), simulation, to ensure that there is no problem, and then right-click the "level" of two-dimensional cutting, select "Edit Tool Path" page to return to work (from the CAM module) , check out the black lines (only elected black line), in the Fx special effects tool, click the last "change direction" tool, and then return to CAM module, right-click the "level" of two-dimensional cutting, select "change the tool path "Two points for" Yes ", when the simulation, the need to move toward the path must be to ensure that anti-clockwise, do not need the path for the clockwise direction, we are commonly known as" reverse-shun outside inside. " Reverse operation is complete, save. Reverse operation flow chart: CAM modules into the calculation of tool paths (double b (c)) right-click cut-dimensional "level" of the Second (c) select Edit-dimensional cutting tool paths from the CAM module to select specific tools and line click the last of a "change direction" tool into the CAM module right-click "levels" of two-dimensional cutting choices under the "Tool to change the path" point of two consecutive "yes"

3, Note:

Two-dimensional cutting, in the dialog box that appears, pay attention to chamfering, whether or not zero, must be changed to zero, or cutting down a small fillet.

4, cutting methods:

1), lines: the use of two-dimensional cutting. Tool along the lines of the outer border of its cutting, cutting down the size and the same settings. 2), online: the use of graphics. Corner Crimping cutting lines, knife-half line, the half-line, the cutting down the size than the set value of the small size of a knife. 3), line: the use of two-dimensional cut in the cutting. Tool along the lines within the frame cutting, cutting the size of the next smaller value than the set size of two knives. Generally used for cutting nested, simply select the text, then by cutting; if the selected text and the frame, then the direct use of two-dimensional cutting, no cutting selected. Produced three-dimensional First, is carved (the word is positive, a positive moment in the material) 1, typesetting (and the same layout badges) 2, into the CAM module, select the word or icon, in the "Year Construction Tool Path - division - three-dimensional group of "three-dimensional carving, double-click in the dialog box that appears select knives, the knife depth (no more than the material thickness of 2 / 3, and the knife 90 degrees less than 6mm, 120 degrees knives in general no more than 5mm, three-dimensional sculpture is based on the width of character strokes of the knife automatically adjusted depth). in Tool Path table, right-click the next level the way the sculpture, the first simulation (simulation of selected entities, depending on the tool path, confirmed), After all the normal, check the frame, double-click the two-dimensional cutting, knife selection, knife depth (larger than the material thickness) (default is 1 chamfering, cut down a small fillet into midnight for the right angle), the machine work, save. Second, anti-carved (the word is anti-, and inscriptions in the negative material) 1), publishing (and the same layout badges) 2), select the character of its curve to the word set 3), all selected to be anti-carved icon of the word and its mirror.

Into the CAM module, methods Ibid. Third, reversing edge 1), is engraved down side After engraved text, select the frame, in the "Create Tool Path - division - two-dimensional group of" double-click the drawing, the dialog box that appears select knife (90 degrees or 120 degrees knife), the depth under the knife. Re-selected to do two-dimensional cutting frame. 2), anti-carved back side Drawing back side first, and then select the frame to do two-dimensional cutting, the material will be cut down to re-stick well to the knife, the final text and icons on the three-dimensional sculpture done. Calculated after the end of the path, right-click the level of simulation entities to choose to see the overall effect Simulation of the reasons for choice of entity: First observation of the overall simulation results, the prevention of back to the text of the hypotenuse was the situation like the above; followed by the word if there are any problems observed, to prevent certain character fonts reason as a result, leading to the node word tie, then you will find the word on by drilling a circle of the kind of situation. If this happens, it is necessary to modify the file. Notes: a. must be replaced after a knife to the depth of Z b. For the anti-carved back side, cutting edge down first, and then three-dimensional sculpture Washing method table (to 1208 cases) A, TYPE3 layout 1, first draw a rectangle, press F2 to adjust into 1200 * 800mm. 2, will be carved on a rectangular Page Center (there are two kinds of methods): a select box, respectively, click on the "alignment tool" in the "vertical center page" and "the level of center page" b, select box, the lock will be closed TYPE3 and drag to the edge of the rectangle. Second, access to CAM module, calculating the path. 1, select group of two-dimensional "scanning" approach. 2, choose a knife, the knife with the largest (such as Z-6 or Z-25). 3, under the knife a depth of 0.2-0.4mm, while choice of pocket "after." 4, in "After the parameters", the "residual" to 0, "coverage" to 80% (usually not changed, otherwise the effect will affect the sculpture.) 5, the machine work to produce documents and to import intraday U. Third, machine operators 1, the boot after the first set carving speed, primarily on the basis of the density of the material to set, can be slowed down first to see the effect of further adjustment. 2, on the knife: first "manual of the sword" will be Z axis to move to the middle of a knife, so do not be a better formation of the elimination. And X, Y coordinates of the "Origin Set" to direct positioning, X is 0, Y for the 800 (the case of ARM system -800) 3, insert U disk, selected files, to work. If not deep enough or too deep, according to "tentative" to adjust, and start all over again.

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.

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.
