摘要
应用Minitab软件对电火花热加工钛合金进行正交试验的参数设计,并对试验结果进行方差分析一确定各个参数对结果影响的显著性;同时进行信噪比分析得到各个指标的最佳参数匹配值。然后应用Image J软件对电子扫描显微镜(SEM)下得到的电火花加工TC4的微小孔表面进行处理分析,统计出微小孔表面的裂纹密度。该方法可以在不采用繁琐的理论公式计算的情况下计算加工表面的孔隙率,具有良好的直观性与较高的精度。
Use the Minitab software to design parameters of TC4 titanium alloy by electrical discharge machining usingorthogonal experiment, and then the results are analyzed by ANOVA to determine the influence of various parameters on theresults of significance; at the same time match the best parameters indicators using signal to noise analysis. Then apply ImageJ software to process and analysis the tiny hole surface of TC4 machined by EDM which are from the scanning electronmicroscope (SEM). Then count the crack density on the tiny hole’s surface. This method not only overcomes the triviality andlimitations of theoretical calculating by formula the porosity on the surface, but also with good Intuition and high precision.
