Here is something similar to what I was trying to describe. He’s talking about aluminum, but I think it could apply to acrylic as well.
@TaitLeswing talks about it as well in this thread:
The trick in the tool path here would be to find a way to have a side of the bit that is clear of the material that you are cutting so as to have a cooling effect and at the same time have space to throw the chips away from the bit.
In the end though, I could be wrong and am just a beginner when it comes to learning about CAM, so if I need correcting… please speak up, because I am here to learn as well as help.
