低速走丝电火花线切割加工断丝原因分析及处理

Analysis and Prevention for Wire-breaking of LS-WEDM

在查阅国内外大量文献的基础上,结合自身的实际工作经验,从电极丝、工作液、伺服控制和脉冲电源控制策略等几个方面,详细分析了低速走丝电火花线切割加工发生断丝现象的主要原因,并提出了相应的改进措施。

How to prevent wire rupture and short is priority research areas in low speed wire electrical discharge machin-ing(LS-WEDM). This paper attempts to analyze the reason of wire-breaking in LS-WEDM from wire electrode, working fluid, servo control and the strategy of pulse generator, etc. , and provides method to do with it.
