摘　　要：运用正交实验方法,研究了冲裁间隙、模具表面粗糙度、冲压速度对高速精密级进冲压中的冲裁断面质量的影响,结果显示,模具表面粗糙度对冲裁断面质量的影响最大,模具表面精度越高,冲裁断面质量越好。因此,尽量采用先进的加工设备和加工工艺以获得尽量高的凸、凹模表面加工精度,对于保证高速精密级进冲压中的冲裁断面质量非常重要。The orthogonal experiment was employed to determine the effect of blanking clearance, die surface roughness and stamping speed on the blanking fracture surface quality. The experient result shows that the die surface roughness has the greatest affection on the blanking fracture surface quality. Higher die surface precision will bring better blanking surface quality. So, it is very important to make the most of advanced process equipment and technology to obtain a high die surface precision and hence guarantee the blanking fracture surface quality in high-speed ＆ precision progressive stamping.
