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.

BP neural networks model which was used to predict the rang of breaking chip of 3D complex groove turning inserts was established, then training and testing of the network was realized with MATLAB, finally ,range of breaking chip of the insert which was designed by the author was predicted. Percentage of accuracy of predicting results reached 91.67% comparing with the chip breaking experiment. This indicates that neural networks can be used to predict rang of breaking chip of turning inserts, so, saving the inserts which is used for cutting experiments and work of experiments, reducing the periodic time of inserts designing and development, increasing the competitive strength of inserts.

It is critical to control chip forming, regular curling and breaking in turning. One method most commonly used is to make chips curl and break with chip-breaking grooves. Chip-breaking groove designing is complex and affected by several factors. Cellular automata is especially used to solve problems in complicated situation, hence this paper adopts cellular automata to design curves of the grooves. After blending the curves through Pro/Engineer into part, an insert with three-dimensional complex groove was developed with EDM. The results of cutting experiment showe a great performance of the grooved insert in turning, reaching the expected goal, and feasibility to design a three-dimensional complex groove insert with cellular automata as well.
