Abstract: In modern decision science the Multiple attribute decision making (MADM) is playing an important role for selection of best from number of alternative. It has been applicable in various areas such as society, economics, military, management, manufacturing, etc., and has been receiving more and more attention over the last decades. To date, however, most research has focused on single-period multi-attribute decision-making in which all the original decision information is given at the same period, and a number of methods have been proposed to solve this kind of problems. In this research work we have considered a novel approach for optimum cutting tool insert selection strategy. In this approach, two well-known Multiple Attribute Decision- Making (MADM) methods such as Simple Additive Weighting (SAW) and Weighted Product Method (WPM) use for a case study of tool insert selection for better surface finish in CNC (Computer Numerical Control) turning operation. In these methods their relative performance are compared with respect to ranking of alternative and from ranking we have selected best tool insert for better surface quality during turning operation on alloy steel using CNC turning centre.
