This paper addresses the optimization strategy for the selection of economic cutting conditions in multipass face rough milling operations on CNC and conventional machine tools. The optimization model of multipass face milling has been built based on criterion of the maximum production rate. The optimization strategy that combines optimization analysis and numerical search technique together has been presented, and the CAM software has been developed. Some experimental results are given to verify the optimization strategy and software, and demonstrate the superiority of multipass over single pass optimization with even greater advantages over handbook recommendations.
