Abstract:

In this dissertation work investigation on machining parametric optimization of friction stir welding is carried out for joining of dissimilar aluminum alloys. This investigation is carried out to for joining of a heat treating aluminium with a non heat treating aluminium alloys. In this study, the variable parameters, that affect much, are taken as input parameters. They are Tool Rotational speed, traverse speed and tilt angle output parameters are as hardness, tensile strength, and yield strength. Work material is taken as AA6061 T6 and AA2024 T0. All the experiments will be conducted on Vertical Machining Centre (VMC). Taguchi method based on L9(33) orthogonal array design of experiment is used and depending upon the design, total 9 experiments are to be performed; The output parameters are measured with the accurate method. Hardness measure in vicker’s hardness tester and tensile stress and yield stress are measured using universal bending machine. Second part of the dissertation work focuses on analysis of results and multi response Optimization. Analysis is done using MINITAB 15 statistical software specifically used for design of experiment analysis. For the verification of the optimized results gained by MINITAB 17 software. The grey relational analysis is used multi response optimization, and regression mathematical model, used for the statistical analysis. All the methods optimized the same level.
