Selection of Cutting Tool Insert in Turning of EN 8 Steel using Multiple Attribute Decision Making (MADM) Methods

A surface finish is very important in turning process. The main objective of this paper is to select a right cutting tool insert from amongst a number of cutting tool inserts during turning of EN 8 steel work piece with good surface finish.In present study number of inserts are five.So it is difficult to select the one best insert amongst five cutting tool inserts. Multiple Attribute Decision Making (MADM) methods provide a ranking of the available alternatives thereby, decision of critical thinking become easier. Hence in this paper a logical procedure used to select best tool insert from alternative tool inserts for better surface finish in turning operation. The procedure based on two well known Multiple Attribute Decision Making (MADM) methods such as Simple Additive Weighting (SAW) and Weighted Product Method (WPM). A tool insert selection index is proposed that evaluates and ranks of tool insert for good surface finish in turning operation.Finally from ranking select the best tool insert for better surface quality
