The deficiency of conventional approaches of the optimization of cutting regimes is analyzed. In view of that cutting process is a dynamic process, the effect of tool wear on selecting cutting regimes is analyzed.

The program of optimization of network method is programmed. At last, the optimal metal cutting parameters in machining bearing rings are resulted.
