Robust conditions for cutting force minimization in polyamide turning process

Abstract

Modeling and optimization is an important aspect of machining processes. Optimization of cutting forces is critically important in turning operations because cutting forces are directly related to several machining performance characteristics. This paper focuses on modeless optimization approach for minimization of cutting force in polyamide turning process. The influence of four cutting parameters, such as cutting speed, feed rate, depth of cut and tool nose radius on main cutting force was analyzed on the basis of the standard L27 Taguchi's orthogonal array. The collected experimental results were analyzed with the help of analysis of means and analysis of variance. The near optimal turning parameters settings were determined considering Taguchi's robust design methodology.
