Özet
The present work focusses on the hard turning of AISI H13 tool steel with PVD-TiN- and CVD-Al2O3-coated ceramic cutting tools. In this context, hard turning tests have been performed under dry cutting conditions at five different cutting speeds (120, 165, 210, 255, and 300 m/min), three different feeds (0.12, 0.18, and 0.24 mm/rev), and a constant depth of cut of 0.6 mm. The main cutting force (Fc), surface roughness (Ra), cutting power (Pc), and temperature (T), as well tool wear mechanisms, have been investigated under these subjected conditions. The outcomes of this study show that while feed plays an important role in the main cutting force and surface roughness, cutting speed also plays an important role in cutting power and temperature. The average main cutting force, surface roughness, cutting power, and temperature are 13, 15, 14, and 11% better when AISI H13 alloy is machined with the PVD-TiN-coated inserts than those in the CVD-Al2O3-coated inserts, respectively. SEM examination also revealed that the abrasion and adhesion mechanism is more effective when AISI H13 alloy is machined with the CVD-Al2O3-coated inserts compared to those in the PVD-TiN-coated inserts.
