Investigation of the Effect on Surface Roughness of Cryogenic Process Applied to Cutting Tool

Abstract

As the cryogenic treatment is the most harmless mechanical healing process in terms of both environmentally friendly and human health, its usage is increasing day by day. In this study, the effect of deep cryogenic process applied on cutting tool material on surface roughness parameters will be investigated. In this context, Sleipner cold work tool steel will be used as workpiece material and PVD (physical vapour decomposition) coated carbide tools will be used as cutting tool. Cutting tool material will be deep cryogenic at -180 °C. A total of 36 cutting tests will be performed for two different cutting tools (untreated, treated) in three different cutting speeds (40, 60, 80 m/min) and three different feed rates (0.04, 0.06, 0.08 mm/rev) combinations. In this study, Taguchi analysis was applied to experimental data. However, analysis of variance, linear and multiple regression analysis were performed. As a result, the effect of the cryogenic process applied to the cutting tool material was examined both experimentally and statistically.
