【摘要】 在正交试验的基础上,采用信噪比分析方法,研究水中钛合金电火花加工过程中参数对加工工艺指标的影响。结合灰关联度分析方法,将多目标参数优化问题转化为单目标灰关联度优化问题。试验表明,基于信噪比和灰关联度相结合的方法,优化后的加工参数能提高钛合金电火花加工效率和表面粗糙度、减小电极损耗。更多还原

【Abstract】 Based on the experiment with orthogonal array,the effect of parameters on the performance in the process of Ti-alloy EDM in tap water is analyzed,with the signal-to-noise ratio method in parameter settings.The multiple performance optimization Problem is transformed into the optimization problem with single objective of grey relational grade.The experimental results indicate that the signal-to-noise ratio and the grey relation analysis method are an effective method which can clearly raise the material remove ratio(MRR),surface roughness(SR),and reduce electrode wear radio of Ti-alloy EDM in Tap Water.更多还原
