Optimisation of Cutting Temperature during the Turing Operation of AISI 1330 Alloy Steel with HSS Cutting Tool using Vegetable Oil-Based Coolants

Abstract

In this study, optimisation of cutting temperature was evaluated during turning of AISI 1330 alloy steel using HSS cutting tool. Experiments were conducted using L27 (34) orthogonal array and each experiment was repeated three times and each test uses a new cutting tool to ensure accurate readings of the surface roughness. The statistical method of signal to noise (S/N) ratio and the analysis of variance (ANOVA) were applied to investigate the effect of cutting speed, feed rate and depth of cut on cutting temperature. The cutting temperature was optimised using the regression equation and confirmation test show acceptable percentage error.
