Multi-Objective Optimization in Machining (Turning) of Copper

Das, Siddharth (2015) Multi-Objective Optimization in Machining (Turning) of Copper. BTech thesis.



A multi-objective optimization problem has been showcased in this work, which involves the use of both the TOPSIS and Utility in the case study in machining of copper. The machining process turning is being studied with the aim of identifying the best possible environmental parameters, so that the present day need of quality and productivity can be satisfied simultaneously. The conventional Taguchi method has the drawback of failing to solve multi-objective optimization cases. Hence we use TOPSIS and Utility model to get rid of this constraint. These two, when coupled with concept of Taguchi creates a single response optimization environment from a multi-response optimization case. The closeness and Utility Index are the governing single objective function that assist the optimization process. This merger of Taguchi concept with TOPSIS/Utility process gives the best]/optimal setting. The data from closeness coefficient and utility index are in turn used to find the S/N ratio based on Taguchi concept. The process environment corresponding to maximum value of S/N ratio of closeness coefficient and utility index is considered as the optimum solution. The verification has been made by other conformity test. The above study gives us an insight for feasible application of the above methodology as multi-response optimization of copper machining process and its off-line control are being studied to improve the productivity as well as the quality
