Learning 101 chamfer collision

[Anonymous]

I'm quite experienced with CAD, but just learning CAM.  I'm 20 hours into practice, videos and learning....

Took me an hour to figure out the 'chamfer tip offset' value in the 2d chamfer operation only moves the tool away from the part along the angle of the tool's chamfer angle(or so I've deduced).

Anyway...why is my file causing a red tool or collision?  And why in the first picture is the tool red, but looks good, but then in the second photo you can see where the simulation ate into the model material?

---by the way, I changed the chamfer tool to  a crazy angle that probably isn't practical, but helped me understand the offset of the tip better. maybe this is messing up the visualization of the simulation.

Thanks for the help, I'm at the point where I'm suffering brain damage learning new skills.

Well you have the tip offset set to 11mm but your tool's flute length is only set to 7mm, so the CAM thinks that it is cutting with the shank and not the flutes. Changing the Chamfer Tip Offset to 6mm corrects the issue.

Hope this helps!

Note: always simulate all previous toolpaths (your whole setup that is) so the CAM knows previous stock is gone or you may wind up with false collision warnings.

Thank you.
