摘　　要：根据切屑上向卷曲的机理及其折断理论,推导出等效槽形宽度的计算式,计算出切削中碳钢的三维复杂槽形等效槽形的宽度。在此基础上建立了可转位车刀片三维复杂槽形典型剖面的槽形曲线元胞自动机模型,提出了元胞演化规则,实现槽形曲线的动态演化和槽形曲线的设计,为三维复杂槽形曲面的设计奠定了基础。This paper derives the formula which computes width of the equivalent groove of the 3D complex groove of the revolvabe turning insert when cutting medium carbon steel based on the theory of chip curling and breaking. The calculation method of the width of equivalent groove is proposed. The cellular automaton model which designs the curve of groove o7 revolvabe turning insert with the 3D complex groove is established. An evolvement rule is presented and a program is prepared to realize the dynamic evolvement and to design the groove curve. This work provides a base for the groove design and optimization.
