Analysis and Optimization of Output Parameters using Taguchi Design Analysis

This paper deals with the analysis and optimization of the surface roughness and tool flank wear when machining super duplex stainless steel with uncoated carbide inserts as cutting tool. The experiments are repeated in three different cutting conditions namely the dry, wet and gas cooled machining. Cutting speed, feed rate and depth of cut are the input turning process parameters considered. Taguchi's Full Factorial design of experiments is followed. Taguchi method is also used to analyze and optimize the output response parameters. Validation experiments are carried out to compare the experimental results with the predicted optimal values. This paper discusses the analysis and optimization of the output responses when machining super duplex stainless steel by referring the recent patents and scholarly articles on the subject of machining, cutting tool and application of such materials.
