Optimization of surface roughness of A1-7075 T6 in CNC end milling

Abstract

The demand for high strength and low weight material in aerospace industries is found to be increasing in fabrication of structures and equipment’s of aircraft and space satellites. Aluminium alloys possesses the characteristics of lightweight and high strength. The identification of the optimum values of input parameters to achieve better surface finish as response parameters is the prime objective of the project. The Aluminium 7075 T651 is worked on the End milling process on the HAAS CNC machine. Different parameters of Cutting Speed, Feed, and Depth of Cut in the Orthogonal Array method using Taguchi method. The results are to be worked on the DOE method on software MINITAB. The material can further be worked upon different input parameters on various machines and for different response parameters. For carrying out the above-mentioned process various papers were referred for guidance and knowledge in the same field of previously carried experiments and results. Various technical concepts and tools like The Taguchi, Orthogonal Array, DOE, ANNOVA, Fuzzy Logic, and Response Parameters etc. were learned from the Published papers and it helped extensively in gaining knowledge required for the experiments to be performed on our project.
