Insert Selection for Turning Operation on CNC Turning Centre using MADM Methods

The effect of cutting tool insert geometry has significant role for surface finish in turning operation. There are many different types of tool inserts with different tool insert geometry are used in turning operation. This paper present a logical procedure to select best tool insert from alternative tool inserts for better surface finish in turning operation. The procedure based on three well known Multiple Attribute Decision Making (MADM) methods such as Analytical Hierarchy Process (AHP), Revised Analytical Hierarchy Process (RAHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). A tool insert selection index is proposed that evaluates and ranks of tool insert for good surface finish in turning operation.
