Wear Behavior of PVD TiAlN, CVD TiN Coated and Cermet Cutting Tools
(2005) Sert, H.; Can, A.; Habali, K.; Okay, F.
This study represents the surface roughness and dimensional deviations when machining the AISI 5140 steel with PVD- TiAlN, CVD- TiN coated and uncoated Cermet cutting tool. All the surface roughness and dimensional data related by machining time for all cutting speed. While the machining time, as a function of tool wear caused the surface roughness and dimensional deviation increasing. Tool life depended on surface roughness is achieved for three type of cutting tool. The suitable cutting conditions were appeared, tool type-cutting speed TiAlN coated carbide tools are suitable under the speed of V=200 m/min. TiN coated cutting tools are more suitable than TiAlN coated cutting tool at cutting speed of V=250 m/min. Minimum tool wear is achieved from TiN coated cutting tool at highest speed of cutting V=250 m/min. Cermet cutting tool has the biggest value of wear rate at all speed of cutting from V=100 to 250 m/min. It is achieved ftom the experiments result that, serial machining tests are the best way to investigate the wear behavior, tool life, surface roughness, and dimensional deviation of cutting tools.
