Design on Groove Curve in Typical Section for 3D Complex Groove Turning Inserts

Abstract

This paper derives formula which computes the width of equivalent groove of the 3D complex groove of the indexable turning insert when cutting medium carbon steel uses the theory of chip curling and breaking. The formula was computed by MATLAB program. The calculation method of the width of equivalent groove is proposed. The cellular automaton model which designs the line-arc curve of groove of indexable turning insert with the 3D complex groove is established. One evolvement rule was confirmed and a program was designed to realize the dynamic evolvement and design of the groove curve. This research provides a base for the groove design and optimization.
