摘要
电火花加工放电脉冲由有效放电脉冲和非有效脉冲等多种状态的脉冲组成,其中有效放电脉冲所占比例决定加工的质量和速度.在实验研究的基础上,分析了各种放电脉冲状态发生的概率以及影响脉冲放电状态的因素,提出了通过检蚀交替脉冲方式来提高有效放电脉冲的概率,并改善电加工效率和质量的加工方法.阐述了检蚀交替脉冲控制方式的电路组成和工作原理.
EDM discharge pulse is composed of various state pulses,such as effective discharge pulse and noneffective discharge pulse, among them the proportion of effective discharge pulse decides machining quality and speed. This paper analyzes the occurrence probability of various discharge pulse states and their influencing factors in the foundation of the experimental research, and suggestions we can raise the probability of the effective discharge pulse and improve the efficiency and quality of electrical process by the method of detection - corrode alternation pulse. This paper represents the circuit composition and its operating principle of control mode of detectioncorrode alternation pulse.
