摘要：In this paper, as workpiece lCrl8Ni9Ti for researching foundation, under turning experiments, with the high speed camera, piezoelectric dynamometer and FEM thermal imager, get relevant data from the cutting process, analyze the effect law of geometry shape and chip type from the cutting force, cutting heat, tool wear and breakage as well, in the removal process. By analyzing and summarizing the tool wear position, study the formation, curl, liquidity of chip and their influencing factors. In short, research on the corresponding relationship between tool wear position and chip type in cutting process, which provides a theoretical basis for the breakage and adhesive prediction of tool in the cutting process
