REGRESSION MODELING OF CUTTING PARAMETERS’ EFFECT TO CUTTING FORCES AND HOLE SURFACE QUALITIES IN DRILLING OF DIEVAR HOT WORK TOOL STEEL
Abstract :
In this study, cutting moments, surface roughness, dimensional accuracy and circularity deviation values were investigated during drilling on Dievar degree of hot work tool steels with various drill bits. The experiments, was completed with Ø16 mm diameter uncoated carbide drill bits and TiAlN coated self-reamed carbide drill bits using coolant fluid on vertical machining center. In experiments, feed rate 0,16 mm/rev and the cutting speed 36, 40, 44, 48 m/min rates were used. The results were modeled by the method of linear regression and polynomial regression curve. Then they were compared with values equal significance. At the same time by analysis of variance, the cutting speed and drill type were investigated on the results of axial feed force, cutting torque, surface roughness, dimensional accuracy and circularity the deviation.
