Relationship between metal cutting performance and material properties of TiC-coated cemented carbide cutting tools

Abstract

The performance of TiC-coated cemented carbide cutting tool inserts was evaluated in steel turning and cast iron milling. The machining behavior was correlated with the properties of the coating and the chemical vapor deposition parameters. It is shown that improved performance can be obtained by controlling the grain size and orientation of the coating, and by choosing appropriate parameters to minimize the formation of the substrate.
