Cutting forces optimization in the turning of UD-GFRP composites under different cutting environment with polycrystalline diamond tool

Abstract

This paper studies the effect of machining parameters on cutting forces (tangential, feed and radial force) for Pultrusion process (UD-GFRP) composite rod in turning  operations using (PCD) tool under different cutting conditions (dry, wet and cooled). The experiments were conducted according to L18 orthogonal array. This paper presents an effective approach for the optimization of turning parameters based on the Taugchi’s method with regression analysis. Second order predictive model covering tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut has been developed at 95% confidence interval for cutting forces. Minimizing cutting forces is considered as an objective. The results are confirmed by further experiments.
