Under hang problem with a 2D Contour

Mattersinmotion — Sat, 17 Aug 2019 17:49:51 GMT

I'm trying to cut a part out using a 2D Contour CAM operation but the under hang on the part is causing problems with my toolpath. How can I cut out the entire circular part and ignore the under hang in this operation?

Here is my project file: https://a360.co/30emkKb

Thanks so much for your assistance!

I would just make it a separate operation. Attached in your file with a different name. I only dealt with the visible component, not sure what you are doing with the invisible ones.

Thanks so much JHackney! That was the answer. It took me a minute to figure out what you did. I had already tried creating a 2D Contour on the top of the circle but I couldn't figure out how to make it cut to the bottom of the piece. IT just run a loop around the top. So the trick was to set the 'Bottom Height' on the 'Heights' tab to 'Model Bottom'. That added the black 'Bottom -13mm' clearance height reference, which causes the tool path to cut all the way to the bottom of the part. As usual, it was so easy once I saw it. I added a screenshot here in case it may help someone else. Thanks again for your help!
