| Abstract: | In this paper, the structural properties of new carbide twist drills are explained simply.Several experiments have been done about the axial thrust force, cutting deformation, machining efficiency, precision and surface roughness of machined hole and the effect of breaking chip when new Carbide twist drills are in use.Experimental results obtained in this case are compared with those of ordinary twist drill. It shows that the new carbide twist drill is a new type of drill with very good performance.Its cutting behavior is much better than that of ordinary twist drill. |
