Tool Wear of (Ti,W)N Coated Cemented Carbide

Abstract

In this study, the tool wear of the (Ti,W)N coated cemented carbide tool, which is a new type coating film, is experimentally investigated in order to clarify the effective tool material for the turning of SCr420H. The main results obtained are as follows: (1) The (Ti,W)N coated cemented carbide has high critical scratch load. (2) In the turning of SCr420H, the wear progress of the (Ti,W)N coated cemented carbide tool is slowest.
