Hi all. I have run into a similar issue where I am calculating a line projection toolpath for use on milling with a robot on a rotary table. I have to use .stl models. In some areas, the toolpath generated will contain some "cusps" in what should be a fairly smooth round section. In these areas, the tool axis will switch direction very abruptly. This causes problems with the robot. What causes this and how can I avoid it. Thank you.

One suggestion: Enable axis smoothing:
