Abstract
In order to enhance cutting performance of a CVD diamond coating tool, short-pulse laser processing is applied to edge sharpening of a commercially-available CVD diamond coating tool. Cutting performance for the sharpened CVD diamond tools was estimated by face turning of cemented carbide (more than HRC 60). By sharpening with the short pulse laser, only uniform flank wear gradually progressed without chipping and crack propagation as is in the case of cutting metals with good ductility. Consequently, the proposed sharpening process with short pulse laser has a high potential to improve cutting performance of CVD diamond coating tools.
