A novel approach to milling cutter temperature analysis with cutting fluid consideration

This study investigates heat transfer to the tool and the cooling efficiency of flood cooling under various cutting conditions using experiments and simulations. An experimental apparatus was developed to measure tool temperature during side milling with cutting fluid. Furthermore, a computationally efficient multiscale simulation method, combining engagement simulation and orthogonal cutting simulation, is introduced to predict process forces and heat transfer to the tool. The findings indicate that accurate orthogonal cutting models enable the multiscale simulation to predict cutting forces and heat transfer. The higher computation speed compared to chip-forming simulations makes the proposed method well-suited for industrial applications.
