Machining Parameters Optimization Based on Objective Function Liniarization

Abstract

Manufacturing process optimization is an ever-actual goal. Within this goal, machining parameters optimization is a very important task. Machining parameters strongly influence the manufacturing costs, process productivity and piece quality. Literature presents a series of optimization methods. The results supplied by these methods are comparable and it is difficult to establish which method is the best. For machining parameters optimization, this paper proposes a novel, simple and efficient method and without additional costs related to new software packages. This approach is based on linear mathematical programming. The major problem that must be solved is the linearization of the mathematical models. In this respect, the present paper proposes an original mathematical pro-cedure of linearizing the objective function. This is the key element of the proposed optimization method. For demonstrating the validity of the method, it is presented a comparison of obtained results of various optimization techniques. This highlights that the proposed method of machining parameters optimization is very good, but simple and cheap.
