Development of a Cutting Tool Utilizing Control of Surface Function Induced by Micro/Nanometer-scale Texture

Dependence of the effect of the texture on the experimental conditions

Abstract

This study investigates a novel cutting tool which has micro/nanometer-scale texture on the surface. In the past experiments, the micro/nanometer-scale textures on the tool surface enables to reduce friction, resulting in the decrease in the cutting forces. This paper describes the effect of the shape of texture on the machinability of aluminum alloy. As a result, it was found that the cutting forces decreased with the pitch and depth of the texture. In addition, the texture was applied to the DLC coated tool, and the machinability was improved by the texture in addition to low friction due to the DLC layer.
