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.
