Dynamic simulation and experimental study of cutting force …

When milling with a ball end-milling cutter, the inclination angle of the cutter axis vector has a significant impact on the cutting process and cutting force due to the high-speed machining. Ko et al. [ 18 ] simulated and evaluated 7 inclination inclinations (0°, 10°, 15°, 20°, 30°, 40°, 45°) to reduce tool wear.
