Anybody notice when using a bowl bit with a finish pass it go past the line? I used it rough cut out a bowl the a finishing pass to remove .05 at 10% step over. It goes past my edge work.
Upload your file and a screen grab showing the tool definition for the bowl bit and a link to the specifications for it?

I have not seen this behavior with my bowl bits when completing a finishing pass?

I think what he means is unlike a pocket path, where the tool stays inside the boundary, with the 3D paths the tool cut to the boundary, i.e. an “on” condition where the center of the tool is on the boundary, and half the diameter is outside the boundary.
That’s just the way 3D paths work. If you need it inside you have to offset the outside boundary inward by the tool radius

Tod1d … that is what is happening. but I chose the facing path under 2d tool paths
The Facing toolpath also does this — it uses the center of the tool so as to ensure that the enter geometry which one wishes to face off is cut — the 3D preview should show this.

Same on texture toolpaths (which I think is a kind of 3d toolpath). With 2d, I do a small offset vector to compensate for the overrun. I have NO idea how that would work with 3d stuff.

Inset by the radius of the tool (or whatever dimension is warranted).
