| Abstract: | Cutting 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 assu... |
| Keywords: | high speed machining cutting temperature cutting force numerical simulation |
