I'm trying to offset chain mill a contour with a large outside diameter
segment (120 mm) using TurboCadCam V3. I can't seem to avoid producing
a tool path that is a series of flats as dictated by the polygon
generated by the CAM program. It seems as if it would be necessary to
define the number of sides to the polygon but I can't find how. What am I
missing?

Any help would be much appreciated.

Regards
Phil
