Method for multi-criteria flank milling of ruled surfaces

摘要

A method for determining machining instructions for flank milling of a workpiece which reduces the undercut by analyzing the cutter orientation at a plurality of orientations to determine an orientation which results in a minimum undercut, smooths the machining instructions by analyzing the movement of the cutter and the workpiece in spherical coordinates and improves machinability by analyzing for near-axial conditions and selecting a modified cutter orientation for such near-axial conditions using a multi-criteria weighting factor.
