Abstract
The optimization of process parameters for efficient machining has been a very important issue in the field of manufacturing. Single objective optimization for a particular response may result into solution which may unseen the effect of process parameters on remaining responses. Hence, multi-objective optimization has become an important issue in order to have desired quality of the product. In this research work, multi-objective optimization of CNC turning of AISI 316N has been dealt with. A multi-objective optimization based on Taguchi's design of experiment and utility concept is used to optimize for the response variables namely, surface finish, material removal rate, temperature at the tool tip and tool wear. The optimal condition obtained is confirmed experimentally. Results thus obtained are in close approximation to each other.
