Abstract

In this study, the tool wear and surface roughness in milling of AISI D2 cold work tool steel workpieces subjected to heat treatments at three different temperatures were examined. The milling tests were carried out dry at four different cutting speeds (70, 90, 110, 130 m/min), three different feed rates (0.05, 0.1, 0.15 mm/tooth) and at a constant cutting depth (0.5 mm). For the milling tests, TiAl+Al2O3+ZrN PVD coated cemented carbide cutting tools were used. The experimental results revealed that surfaces that can be achieved by grinding were obtained at low feed rate and cutting speed. The lowest surface roughness value was obtained at 70 m/min cutting speed and 0.05 mm/tooth feed rate, while the highest surface roughness value was obtained at 130 m/min cutting speed and 0.15 mm/tooth feed rate. The tool wear was identified as the plastic deformation for the cutting tools used for milling the hardest workpiece.
