Research on Kinematic Analysis and Post Processing Arithmetic for NC Machine tool for Bonnet Tool Polishing

摘要

Bonnet tool polishing, combined traditional optical polishing technique with modern NC technology, is an novel optical polishing technique. As the motion control and material removal process is different from metal cutting NC machine tool, the NC programming for bonnet tool polishing NC machine tools cannot be carried out with commercial CAM software. This paper analyses the kinematics of feed mechanism and precession mechanism using coordinate transformation method and sets up the feed and precession kinematics equations. The arithmetic of post processing applied to NC automatic programming system is proposed according to kinematics equations and detail bonnet tool polishing technique.
