Abstract:For cutting a large screw, the cutting force and temperature have direct impact on machined surface quality, such as accumulated pitch error in geometric error. Excited by cutting force, the axial deflections directly affecting accumulated pitch error were studied based on the beam theory. By experiments, the axial cutting force was predicted with a 96% confident interval, and the tool number and cutting depth were found to be significant terms. Tested under increasing cutting speeds, the temperature rise of w… Show more
