摘　　要：研究电火花加工参数对工艺指标的影响,为了实现加工参数的优化选择,使用紫铜电极对QT700-2进行了电火花加工试验,选择加工速度vm、电极损耗速度vE、双边侧面间隙S及相对损耗比θ作为工艺指标,采用灰色关联理论,分析了主要电参数对加工指标的影响关联程度,对主要电加工参数进行了优化,得出以单项工艺指标和多项工艺指标为优化目标的电加工参数组合.优化结果表明,优化后的电加工参数对减小电极损耗速度vE、双边侧面间隙S及相对损耗比θ具有比较明显的效果.Studies the influence of electric parameters on machining targets in achieving parameter optimization, when electrical discharge machining oil supply tank with copper electrodes. Some parameters such as processing speed, electrode wear speed, machining gap and relative wear ratio are chosen as machining targets, applying grey theory to analyze the correlation degree between electric parameters and machining targets. Grey theory is put forward to optimize electric parameters, obtaining optimized parameters in single-object and multi-objects. Experimental results indicated that optimized parameters have a distinct effect on reducing electrode wearing speed and relative wear when adopting the optimized parameters.
