Wear of Coated Tungsten Carbide Tool In Cutting H.S. Steel Ⅺ

In last part we know that the tool wear mechanism and cutting temperature of tungsten carbide tools in the cutting speed range from 0.50 m/s to 1.00 m/s are similar. And this part we come to get a final conclusion based on the above experiments and analysis.

4. Conclusion

In this study, to clarify the effectiveness of aluminum-chromium coating film for cutting hardened sintered steels, tool wear was experimentally investigated. The hardened sintered steel was   turned with an aluminum-chromium based coated tungsten carbide tool according to a physical vapor deposition (PVD) method. Moreover, the tool wear of the aluminum-chromium based coated item was compared with that of the (Ti,Al)N coated tools.
