摘　　要：数控高速走丝电火花线切割加工,首先必须保证在切割过程中不断丝。如果在切割工件过程中发生断丝,不仅会带来重新上丝的麻烦,造成一定的经济损失,而且会在工件上产生断丝痕迹,影响加工质量,严重时会造成工件报废。本文介绍了在线切割加工中的断丝问题,论述了产生断丝的原因,从线切割机床和工艺特点出发,对防止产生断丝的措施进行了探讨。CNC high speed wire-EDM wire cutting must first ensure that the process of constantly cutting wire. If cutting the broken wire occurred in the process,it will not only be brought to the trouble caused by the silk, certain economic losses, and will be on the work piece produce broken wires, affect machining quality, traces causing serious workpiece scrap. This paper introduced the cutting line in the broken wire problem, discussed the reasons for broken wires resulting from the cutting machine and process characteristics on measures to prevent the generation of broken wires.
