| Abstract: | In this paper, we study the structural characteristics of a kind of new solid carbide twist drills with three major cutting edges. Several experiments have been done about the cutting ability, machining efficiency, drilling forces, precision and surface roughness of machined hole and the effect of breaking chip when this kind of twist drills is in use. The experimental results have shown that the new kind of twist drill is a new type of drills with very good performance. Its cutting behavior is much better than that of ordinary HSS twist drill. |
