Abstract


Most of the currently available optimization strategies for machining operations are based on economic parameters such as production cost and machining time. In most cases, however, size tolerance is the first criterion for accepting the manufactured parts. As a result, these strategies might not be applicable in practice, despite their economic advantages. This paper proposes a new optimization strategy for a single-pass peripheral end milling process based on both technical and economic parameters, namely, specified parts tolerances and economical cutting speeds. First, the cutting speed is selected based on an economic parameter, such as the minimum cost per part or the maximum production rate. Then the circular direction search optimization strategy is employed to determine the best combination of feed rate and radial depth of cut to satisfy the specified part tolerance. The results indicate that the proposed strategy can be implemented successfully for process optimization. By being based on both technical and economic parameters, it provides a rational solution to the peripheral end milling optimization problem.
