Cutting Performance of (Ti, V) N Coated Cemented Carbide Tools

Tool Wear in Cutting of Stainless Steel

Abstract

In this study, the (Ti, V)N coated cemented carbide tools that have several contents of Ti and V are used. In order to clarify the effective tool material for the turning of SUS310S, the tool wear of the (Ti, V)N coated cemented carbide tool is experimentally investigated. The main results obtained are as follows: (1) The Ti75V25N coated cemented carbide has high micro-hardness and high critical scratch load. (2) The Ti75V25N coated cemented carbide tool is the most effective tool material for the turning of SUS310S.
