Optimizing Surface Roughness and Flank Wear on Hard Turning Process Using Taguchi Parameter Design

This paper presents an application of the Taguchi method parameter design to optimize the surface roughness, tool wear and cutting force by hard turning process. The Taguchi parameter design method is an efficient method in which response variable can be optimized, given various controls and using fewer experimental runs. Hard turning is the latest trend in all manufacturing industries and it is a profitable alternative to grinding. The hard turning removes unwanted material in a single cut rather than grinding in order to reduce process time, set up time, operating cost, surface roughness and to produce components economically. In the process of analyses, material having hardness between 54-58 was considered and three CBN cutting tool were used to conduct 18 tests. The response of surface roughness and flank wear taken for discussion and analyses. The experimental results show that there is a good agreement between surface roughness and flank wear both by equations and experiments by Taguchi method.
