Optimization of Effects of Pocket Tool Path Strategies and Cutting Parameters on Surface Quality

In this study, surface roughness and cutting forces were investigated experimentally in milling of Al 7075 material by DLC coated end-mill cutting tools. Effect of tool path, feed and cutting depths on surface roughness and cutting forces was examined. Taguchi technique was used for optimization of the milling process. Also, a variance analysis (ANOVA) was used for determination of effect of each parameter on the obtained results. In conclusion, the relationship between the dependent and the independent variables was modelled with regression analysis. Optimal machinability of Al 7075 material by DLC coated end-mill was determined in this study.
