Abstract
Abstract WEDM is an important process method for machining copper tungsten alloy electrode. Using orthogonal experiment, range analysis and variance analysis, the influence of pulse width, peak current and servo voltage on the material removal rate in WEDM of copper tungsten alloy was studied. The parameter combination was optimized under the maximum material removal rate. The results show that after the duty cycle is set, the degree of influence on material removal rate is as follows: peak current, servo voltage and pulse width. Ton 50μs, IP 12A and SV 8V, the maximum material removal rate is 25.28 mm2/min, which has an important theoretical guidance for the realization of rapid and efficient WEDM processing of copper tungsten alloy electrode.
