基于正交试验的电火花加工实验分析

由于电参数的改变会影响电火花加工的性能，为了研究在不同电参数条件下加工性能的变化规律，采用了正交试验研究用铜电极对45#钢进行电火花加工实验时脉冲宽度、峰值电流和脉冲间隔对加工速度、电极损耗的影响规律。通过一系列实验研究和理论分析得知：电流是影响电加工特性的主要因素，在脉冲宽度变化较大时，脉宽的改变对加工性能的影响也非常显著；当脉宽变化不大时，脉冲间隔对加工性能的影响较显著。研究结论为推动电火花加工，提高模具的加工精度提供了理论指导意义。

Experimental Analysis of EDM Based on Orthogonal Test

The electrical parameters variation can influence machining performance(MP)of elect rical discharge machining(EDM).In order to investigate the MP variation rules under different elect rical parameters,orthogonal test uses copper electrode to machine 45# steel.Experiment results show that summit current is an important factor affecting MP.If pulse width fluctuates a lot,the pulse width variation will influence MP obviously.If pulse width variation is not obvious,pulse interval will become the main affecting ...
