Abstract:

A method for making a cutting insert for use in an ID rotary cutter includes obtaining the profile of a convex surface portion of a finished part to be milled with the cutter, translating the profile a minimum distance away from a reference axis for the convex surface portion, and generating a reference contour by rotating the translated profile about the reference axis. A reference profile for a cutting edge of the cutting insert is obtained as the intersection of the reference contour with a reference plane that is disposed at a predetermined helix angle relative to the reference axis.
