英文摘要	Because of the influence of tool geometry, when the fine slotting cutter is cutting, the cutting condition at every point of the type line cutting edge varies, which will lead to uneven loading on the whole cutting edge. Finally, partial earlier failure of the cutter would be initiated. To solve this problem, this paper presented a cutting simulation of the slotting cutter with zero rake angle, which could draw the variation law of cutting force at different locations on the type line. On the basis of micro-elemental milling force model, this paper established mathematical models of different sections along the turning axis of cutting tool, in which the relief angle changed to adapt to the variation of cutting force. The variation law of relief angle could be found by utilizing liner regression analysis. Then the 3D model of tool could be reconstructed. According to cutting experiment analysis of the reconstructed model, the distribution of cutting force at every point of the cutting edge tended to be reasonable, and the rationality of the optimal model was proved. This will offer a new idea to improve the level of slotting cutter design as well as a reference of complex forming cutter design that was completed by using the modern design method. © (2014) Trans Tech Publications.
