The optimal cutting-parameter selection of heavy cutting process in side milling for SUS304 stainless steel

摘要

This paper presents an optimal cutting-parameter design of heavy cutting in side milling for SUS304 stainless steel. The orthogonal array with grey-fuzzy logics is applied to optimize the side milling process with multiple performance characteristics. A grey-fuzzy reasoning grade obtained from the grey-fuzzy logics analysis is used as a performance index to determine the optimal cutting parameters. The selected cutting parameters are spindle speed, feed per tooth, axial depth of cut and radial depth of cut, while the considered performance characteristics are tool life and metal removal rate. The results of confirmation experiments reveal that grey-fuzzy logics can effectively acquire an optimal combination of the cutting parameters. Hence, performance in the side milling process for heavy cutting can be significantly improved through this approach.
