摘要：
Heat flux changes in grind-hardening process resulting in uneven distribution of grind-hardening layer depth, making it more difficult to produce a hardened layer in the grinding cutting-in and cutting-out area, leading to uneven distribution of the hardening layer depth in grinding stable region. This paper firstly studied the grinding force. Secondly, grinding distortion is analyzed by thermal-mechanical coupling numerical analysis. The grinding distortion makes the actual grinding depth deeper. According to the distortion, the actual cutting depth can be concluded. The actual cutting depth affects the variation of grinding force. Thirdly, the relationship among grinding force, grinding distortion, and the distribution of the hardening layer depth is presented in the paper. At last, variable grinding cutting depth to control grinding force is put forward to improve the uniformity of the distribution of the hardening layer and is verified by experiment.
