B33 Evaluation of chisel edge wear in micro drilling process for high-functional resin

In recent days, production of medical parts made by high-functional resin by cutting or drilling process has been increasing. In the drilling process, chisel wear on cutting edge has become a serious problem. Therefore, we examined cutting conditions to suppress the chisel wear by measuring the cutting edge wear and observation of the shape of the chisel with a large number of drilling in a variety of cutting conditions.
