ANALYSIS TO DEFORMATION IN METAL CUTTING AND HIGH SPEED MICROPHOTOGRAPHY
金属切削变形与显微高速摄影分析

The deformated patterns of microstructures during metal cutting were analyzed by means of high speed microphotography. The results show that the characters of plastic deformation are inhomogeneity and harmonizing in polycrystal Stereoscopic plastic deformation is appeared as wave and undulatory for crystal grain as an unit. It is restricted by crystal boundaries.
