In the contribution, a new non-deterministic optimization approach to complex optimization of cutting parameters in machining is proposed. It applies artificial neural networks to solve the cutting conditions optimization problem. The developed approach is based on the "maximum production rate criterion and incorporates four technological constraints. By selection of optimum cutting conditions it is possible to reach a favourable ratio between the low machining costs and high productivity taking into account the given limitation of the cutting process. First, the problem of determining the optimum machining parameters is formulated as a multiple-objective optimization problem. Then, neural networks are proposed to represent manufacturers preference structures. Experimental results show that the proposed algorithm for solving the non-linear-constrained optimization problems is efficient and can be integrated into an intelligent manufacturing systems. To demonstrate the performance of the proposed approach, an illustrative example is discussed in detail.
