Machining Parameters Optimization for Form Milling the Gear Using Improved Harmony Search Algorithm

Machining parameters optimization in face-milling the hypoid gear was often needed in order to obtain lowest cost or highest productivity. In this study, the optimum value of machining parameters including feed rate, rotation speed are obtained using improved harmony search algorithm(IHSA), to yield minimum total time while considering constrains such as allowable cutting speed, tool life and machine tool capabilities. Results indicate that the IHSA converged to optimum solution with similar accuracy in comparison with the genetic algorithm (GA).
