本文采用了直接检测放电维持电压上的高频,随机振荡信号的频谱分布和强度的方法来鉴别加工中的放电状态。在此基础上进一步研制出了“电火花加工放电状态分析仪”。该仪器可对加工中正常放电脉冲时间利用率(包括过渡不稳定电弧率)和相对非正常放电时间(其中包括稳定电弧和短路的时间率)及相对空载时间进行表头显示,并对过渡不稳定电弧率和稳定电弧率分别单独在两个发光电平指示器中显示出来;本仪器可将以上五个参数用模似量输
In this paper, a direct detection of discharge to maintain the voltage on the high-frequency, random oscillation signal spectrum distribution and intensity of the method to identify the processing of the discharge status. On this basis, further developed a “EDM discharge state analyzer.” The instrument can process the normal discharge pulse time utilization (including the transitional unstable arc rate) and the relative non-normal discharge time (including the stable arc and short-circuit the time rate) and the relative dead time for header display, and the transition Unstable arc rate and stable arc rate are separately displayed in two light level indicators; the instrument can be used to simulate the above five parameters lose
