Abstract
This study presents a method for extending the life of tools in cutting of Carbon-fiber-reinforced plastics (CFRP). In the previous study, our research group found that the use of two layer tool, which has a wear resistance distribution due to the use of a combination of two different materials with different hardnesses, is effective for decreasing cutting force during machining of CFRP composites. In the two layer tool, a narrow region of the flank face close to the tool edge and the whole of the rake face were made of a material with a relatively high wear resistance, e.g., diamond or polycrystalline diamond (PCD). In contrast, the other region of the flank face was made of a material with a relatively low wear resistance, e.g., tungsten carbide (WC-Co). In this study, based on some experiments, the effect of the thickness of high wear resistance region on the reduction effects of cutting forces was investigated.
