摘　　要：在民用和军工领域存在许多环状工件需要分块切割,但现有电火花线切割加工方法效率低、内应力大,通过发明、制造了一种圆形多工位同步加工的电火花线切割机床,采用一根电极丝在机床不同位置,对环状工件同步进行径向切割。介绍了机床总体结构设计、电源研制、控制系统开发,并通过工艺试验验证了机床的可行性。In the field of civil and military industry,there are many annular parts that need to be cut into several blocks,but the existing wire cut electrical discharge machining(WEDM)methods have problems of low efficiency and high internal stress.In this paper,a circular multi-station synchronous WEDM machine tool is invented and manufactured,in which an electrode wire is used to cut the annular parts synchronously in different positions of the machine tool.In this paper,the overall structure design,the development of power supply and control system are introduced,and the preliminary process experiments are carried out,which prove the feasibility of machine tools.
