摘　　要：应用正交试验法研究了硬态切削冷挤压凸模时,切削用量与刀尖圆弧半径对加工表面粗糙度的影响规律,找出了影响加工表面粗糙度的主要因素,得出了最优切削加工参数组合,最后通过了验证试验。The effect of cutting data and corner radius of tool on surface roughness during hard machining cold extrusion of the punch was studied by using orthogonal test. The results contribute to find the major factor to influence the surface roughness and obtain the optimum cutting parameters and then a demonstration experiment was conducted.
