进行了往复走丝电火花线切割加工工作液的寿命试验，分析了工作液寿命与脉冲概率之间的关系。从工作液的性能及其对极间放电特性的影响角度，分析了工作液失效前后的极间状况和放电特性，提出工作液寿命最终体现在放电脉冲概率方面，并与其呈现一定的关系。研究了往复走丝电火花线切割加工的有效放电脉冲概率与切割效率的变化关系及其对加工表面质量的影响，结果发现：当有效放电概率小于70%时，切割效率降低，加工表面质量变差，可作为判断工作液失效的指标。据此研制了工作液寿命的检测装置，该装置可有效实时监控工作液的寿命状况。

Life test of dielectric fluid in high speed wire-cut electrical discharge machining (HSWEDM) was carried out to analyze the relationship between the dielectric fluid life and the discharge pulse probability. In terms of the working fluid properties and the effect on the discharge characteristics of discharge gap,discharge gap and discharge characteristics before and after the failure of dielectric fluid were analyzed. The relationship between the dielectric fluid life and the discharge pulse probability was proposed. The relationship between the discharge pulse probability and the cutting efficiency and surface quality was studied ,when the effective discharge pulse pro-bability is less than 70 %,the cutting efficiency is reduced and the surface quality becomes poor ,which can be used as the index of the failure of dielectric fluid. Whereby the device of detecting the dielectric fluid life was invented which can monitor the life condition of dielectric fluid effectively.
