Abstract
Acceleration of tool crater wear in high-speed cutting is usually attributed to the high tool-chip interface temperature increasing diffusion coefficient(DEff), where the role of microstructure is ignored. The main purpose of this paper is to study the influence of microstructure evolution at second shear zone on tool element diffusion ability and crater wear with increasing cutting speed, which establishes the base for the research of tool wear evolution forecast. Based on the Orthogonal turning experiment of AISI1045 steel, the effect of cutting speed(V) on crater wear and microstructure of second shear zone was notable: (1) the crater wear increased drastically at 361 m min−1
