Modeling of hard turning: effect of tool geometry on cutting force

Z.Y. Shi, Z.Q. Liu, C.M. Cao

Abstract. Hard machining for manufacturing dies and molds offers various advantages, but the productivity is often limited, mainly by tool life. This study investigates the influence of cutting tool geometry on the cutting forces by utilizing finite element simulations (FEM). A set of cutting conditions in numerical FEM were conducted by using four different shaped cutting tools and axial force, radial force and tangential force were found. The results of this research help to explain the conclusion that for cylindrical control, the equation of the actual geometry of the S-shaped inserts involved in cutting is a sphere; that of C-shaped, D-shaped and Tshaped inserts involved in cutting is an ellipsoid with different lengths of short-half axis.
Keywords: tool geometry, material flow stress, short-half-axial, cutting force
