Abstract
As a fundamental study for developing a self-sharpening tool in CFRP machining, an orthogonal cutting test was carried out using a CFRP plate and a cutting tool made of high-speed steel. Through the cutting test, time changes in cutting loads and tool wear volumes were measured. As a result, it was found that the orientation direction of carbon fibers and the flank angle of the cutting tool are important factors to extend the tool life in CFRP cutting.
