Taguchi and ANOVA-based Optimization of CNC Milling Parameters for Aluminium 7075 Alloy

This study is aimed at optimizing the CNC milling parameters for Aluminium 7075 alloy, using Taguchi and Analysis of Variance (ANOVA) approaches. The high-strength alloy has applications in the automobile and aerospace industries. The cutting depth, speed of milling and rate of feed were adjusted to methodically enhance the machining performance and efficiency; surface roughness was studied in these metrics. Taguchi and ANOVA approaches were helpful in optimizing the parameters to lower cost, improve machining quality and enhance the productivity of Aluminium 7075 alloy.
