For production, my larger Milltronics VMC will be used, so rigidity seems essentially moot for this material. Given the small size of my Taig, I'd prefer to feed it a little quicker in two. I'll do a small production run of these parts, and I'll probably just use an off-the-shelf tapered endmill, but wanted the 3D practice (very novice user here). This disc must have a 5 degree draft on the vertical wall. My issue is the program seems to ignore my input in the u/d window.īasically, my real project is milling a 4' diameter 'disc' out of 1/4' ABS plastic sheet on a small benchtop CNC.

I regularly use the u/d button for 2.5D milling, and am familiar with with the auto-roughing portion of the window. I use 2 H value all the time for the same toolThanks for the tips. 005 finish pass and the 3d contour allows you can just offset the tool for finish pass. In the lower part of the u/d dialog box you need to check the auto-ruogh box and put in a value for depth of cut. I'd like to make this part in 2 lighter passes, finish passes aren't required. My test programs would simply plunge to full depth (.235 in this case) and begin milling. I will experiment with the U/D settings, perhaps I did not have a value entered correctly. Also have been using machine 'auto' once I generate the code. I had discovered the 3D button on the CAM side, after getting several 2D toolpaths from my 3D surface.

MoldmkerThank you for your time your information is very helpful. You may want to put it on a separate layer to blank it. To do this, highlight the code just created and select Edit > Geometry from NC and this will backplot the code into the CAD window. Sometimes it's handy to have the actual roughing passes for future reference. Note that the stepped down toolpath is only shown temporarily. This should show the toolpath being roughed down in steps. Set your U/D window with Roughing Enabled and define an increment.ĭisregard the Tool Cutting Depth, with 3D turned on it isn't used.Īfter creating your 3D path with Planar or other method, use CutAuto to create the code. On CAM side, make sure your 3D button is on.
