Optimization of Surface Roughness and Material Removal Rate in Milling of Aluminum Alloy 7475 using Taguchi Technique
Modern structural applications demands reduction in weight. Al alloys are the best choice for the reduction of weight. AA7475 alloy has many applications in aerospace industry due to its high strength to weight ratio.
Milling is the mostly used machining process in all industries and machine shops for machining parts to precise sizes and shapes. In this thesis experiments are conducted to improve the surface finish quality, material removal rate of Aluminum alloy 7475 workpiece. L9 orthogonal array has been selected for conducting the experiment. A series of 9 experiments are conducted by varying the milling parameters spindle speed, feed rate, depth of cut, and to optimize the better machining parameters using Taguchi technique. Here we analyzed the taguchi’s method and RSM method for the appropriate results.
