摘要：

A modeling of diffusion wear is proposed for high speed cutting processes. Diffusion at the tool-chip interface is controlled by the contact temperature. Cratering and tool life are analyzed in terms of cutting conditions (cutting velocity, feed, rake angle), friction characteristics and material properties. Optimal cutting conditions can be found with respect to tool life and volume of material removal. Comparison with experimental observations show the potentiality of the modeling.
