![]() ![]() I could see how it would cause some confusion though if I'm trying to make something with a flat bottom. In practice yes, but it theory it should be possible. You could progressively remove more and more material with smaller and smaller bits, but your part is 1/2" thick and at some point it will be impossible to have an endmill with 1/2" length flutes that is any smaller than probably 3/32 (I'm guessing).ġ/ Come to terms that doing an operation only on this axis is going to result in radiused cornersĢ/ Redesign your part so that it is actually an assemble of multiple pieces, such that you can cut each piece in a orientation that allows square corners.ģ/ Use the CNC machine to cut a mold, which is the negative of this part and will have square corners, then cast the final part. What you're describing about approaching the Z height but not wanting a chamfer - it's not possible to get perfectly into the corner at any depth other than 0 without chamfering if you're using a v-groove bit. "Profile" is the standard name for that operation. Sorry, they call the profile operation "2D Contour" in the F360 interface (unless it's a perfect circle, then it's a different operation called "Circular"). Here's the F360 file if anyone's interested in seeing what I've got so far. My current thought is to implement scenario A, and try to add a 2d pocketing operation with the tool set to the v-groove bit to clean up the remainder, but F360 is giving me errors since the tool type isn't what it expects.Īny suggestions for me? Surely there must be a way to do this, but I'm just getting started and I can't seem to find a tutorial or explanation of the process that I can learn from and adapt to my needs. I am unable to achieve my desired result of a flat bottom pocket with beveled sides in F360 either. I am unable to replicate Scenario B at all. ![]() I am able to reproduce scenario A in F360 by creating two separate tool paths ( image here showing problems). Problem with B is that it takes forever and there's a lot of wear on the point of the bit. Problem with version A is that it will leave places without a flat bottom where the 1/4" end mill can't fit. I can also do the same operation without using a 1/4" end mill to remove the bulk of the material, and Estlcam simply does lots (and lots) of passes with the v-groove bit to empty out the pocket. I can select a roughing tool to remove the majority of the material, and then it cleans up the edges and sharp corners using the v-groove bit by varying the z-axis height. In Estlcam, I can select a shape outline and ask it to carve the inside. I'm trying to up my game, but I've hit a bit of a snag. It's creator recommends Estlcam, which is great, but it's definitely not as powerful/flexible as Fusion 360.
