Abstract

In this study, the effect of cryogenic treatment and machining parameters on cutting force and temperature were investigated in the dry turning of C45steel with treated and untreated M2 HSS tool with the radial nose of 0.4mm, are optimized by using the statistical method. Pilot experiments have carried out in three different speeds (38.6, 57.5, 62.8 m/min) by three different depth of cut (0.2, 0.4, 0.6 mm) and feed rates (0.046, 0.062, 0.087 mm/rev). Experiments were carried out based on L27 orthogonal array (33) three levels and three factors, analysis of variance (ANOVA) and S/N Ratio is employed to determine the most significant factor in each response. The result shows that the depth of cut is the most significant factor for both treated and untreated tool on cutting force, temperature followed by cutting speed and feed rate has less significance, from statistical method to obtain considerably reduced the cutting force of HSS tool by 9.11%and temperature by 11.5%, while depth of cut was the dominating factor for both.
