An analytical model for transient temperature distributions in coated carbide cutting tools

The cutting temperature during metal cutting processes has been recognized as one of major factors influencing the tool performance and workpiece geometry accuracy. This paper presents analyses of the one-dimensional transient temperature distributions in monolayer coated tools. The analytical formulae of the transient temperature distributions for the monolayer cutting tools are obtained using Laplace Transform. Computations of the temperature distributions in monolayer coated tools reveal that such factors as the coating material, substrate material and coating thickness have some influence on temperature distributions in monolayer coated tools. The present work provides some data for selecting appropriate coating materials to reduce temperature within coated tools.
