| Abstract: | In view of the bending and breaking problems of small diameter drills in the process of drilling, a 3D model of small diame-ter twist drills is established by using PRO/E software. Based on ANSYS Workbench software, this paper analyzes the change rules of inherent frequency, deformation, stress and strain during the process of drilling, discusses the effects of clamping length, spiral groove＇s length, materials and other factors on the strength and stiffness of twist drills and presents some measures to enhance the per-formance of twist drills. |
