Fem thermo-mechanical simulation of cutting force, torque and temperatures in high-speed drilling process of aisi 4140

This paper presents finite element simulations of cutting force, torque, chip formation and temperature in high-speed drilling of AISI 4140 alloy. The FEM simulations were conducted at a cutting speed of 200 m/min and a feed rate of 0.2 mm/rev., using a TiAlN multilayer coated solid carbide drill. The temperature field in a tool and the forces that appear in the cutting process have an essential effect on the tool wear mechanism and life. Experimental findings confirmed the predicted cutting forces, torques, and chips shape. It was observed that the predicted and measured values were found to be in good agreement.
