基于电火花线切割加工工艺指标对加工质量的影响分析

Based on the Analysis of the Influence of EDM Machining Parameters on Machining Quality

线切割机床能实现精密度高的零件加工,但断丝的影响一直难以让这一优势发挥,本文以加工粗糙度和精度来衡量加工质量,针对线切割电极丝的选择、工作液、进给速度以及系列电参数指标的调试,通过示波器观察加工中的脉冲波形。通过波形图得到工件蚀除的程度与线速度与进给速度的匹配有关系,当它们达到最佳配置时,工件的表面纹路细腻、均匀,像面镜子一样光亮。研究成果对今后的线切割加工影响因素有一定的参考价值。

The wire-cutting machine can process the parts with high precision,but the influence of broken wire has been difficult to make use of this advantage,the pulse waveform in machining is observed by an oscilloscope.The relationship between the degree of erosion and the match of linear velocity and feed velocity is obtained by the waveform graph.When they reach the best match,the surface of the workpiece is fine,even and as bright as a mirror.The research results have certain reference value to the influence factors of WEDM in the future.
