OPTIMIZATION OF MULTI-PASS FACE-MILLING USING GENETIC ALGORITHM AND USING HARMONY SEARCH ALGORITHM

This study presents a harmony search (HS) algorithm to determine the optimum cutting parameters for multi-pass face-milling. The optimum value of machining parameters including number of passes, depth of cut in each pass, speed and feed are obtained to minimize total production cost while considering technological constraints such as allowable speed, feed, surface finish, tool life and machine tool capabilities. An illustrative example is used to demonstrate the ability of the HS algorithm and for validation purpose, the genetic algorithm (GA) is used to solve the same problem. Comparison of Results reveals that the HS algorithm converges to optimum solution with higher accuracy in comparison with GA.
