Multi objective optimization of cutting parameters in turning operation using Taguchi method

Sutar, R (2014) Multi objective optimization of cutting parameters in turning operation using Taguchi method. BTech thesis.



This paper refers to parametric optimization of turning process applying Taguchi method in order to improve quality of manufacturing goods, and engineering development of designs for studying variation.SS-304 is used as work-piece for carrying out experiment to optimize material removal rate and surface roughness. There are three machining parameters i.e. spindle speed, feed rate and depth of cut. Different experiments are done by varying one parameter and keeping other two fixed so that optimized value of each parameter can be obtained. In this project dry turning of S. S. 304 graded steel as a work piece and carbide insert tool (SNMG120408MS, SNMG432MS) is performed. The range of cutting parameters are cutting speed (40, 66 and 92 m/min), feed rate (0.05, 0.1 and 0.15 mm/rev), depth of cut (0.25, 0.5 and 0.75 mm). Taguchi orthogonal array is designed with three levels of turning parameters with the help of software Minitab version 16. Taguchi method stresses the importance of studying the response variation using the signal to noise (S/N) ratio, resulting in minimization of quality characteristic variation due to uncontrolled parameters. It is predicted that Taguchi method is a good method for optimization of various machining parameters as it reduces number of experiments. The results indicate the optimum values of the input factors and the results are conformed by a confirmatory test.
