摘　　要：利用慢走丝线切割编程原理以及机床上下异形加工功能的特点,实例分析如何采用偏移计算、添加补偿点、上下异形(锥度加工)等加工原理进行圆弧凹模刃口直边的加工,从而获得均匀的圆弧冲孔刃口直边,大大提高凹模刃口的使用寿命,降低模具加工费用,缩短模具制造周期。Based on the programming principle of low speed NC WEDM and characteristic of different upper and lower machining functions for special-shaped part, a practical example was used to investigate the machining of the straight cutting edge of arc die by using the processing principles such as offset calculation, adding of compensation points, different upper and lower machining （taper machining）. Therefore, uniform straight cutting edge can be achieved and the service life of the die cutting edge be greatly increased.

关 键 词：线切割 偏移计算 圆弧刃口 锥度加工
