Other AbstractCutting temperature and cutting force are two important physical characteristics to describe the high speed machining process;they are the chief contents of high speed machining research.Based on the FEM numerical simulation which was validated by cutting experiments,the changing regularities of temperature and cutting forces with cutting speed in high speed machining of TiAl6V4 are researched systematically.The physical origins of these changing regularities are revealed,and the existence of Salomon’s assumptions is further discussed.The results of the study indicate that,with increasing the cutting speed,the tool-chip contact temperature always increases,while the workpiece temperature decreases after the cutting speed reaches a certain critical point.Furthermore,increasing the cutting speed rises the primary and secondary shear zone temperature and shortens the tool-chip contact length,which finally decreases the cutting force
