摘　　要：应用数控车床对大型球面或圆弧面工件进行加工时 ,如果按“刀类点”来设定或修正“刀补值” ,会使加工出的曲面与实际要求的尺寸产生较大的形状误差。优化工艺进行编程时 ,以刀具耐用度为优化目标 ,建立了刀具耐用度和切削速度的T v曲线 ,根据曲线所示的“驼峰”规律合理调节切削速度 ,可有效避免刀具在高磨损区的加工磨损 ,从而提高刀具耐用度 ,同时优化了加工时间 。To avoid biggish shape error of curved surface in machining lareg-size spherical cambered surface with numerical-controlled lathe,the process technology is optimized.In programming for the optimum techology,by taking the durability of the cutter as the optimized object,the cutter's duradility vs cutting speed curve is established.The cutting speed can be regulated retionally according to the 'hump'pattern of the curve,thereby the wear of the cutter can be effectively reduced and its durability can be improved.
