The study of cutting force, temperature, and geometric error in cutting a large screw

For cutting a large screw, the force and temperature have direct impact on machined surface quality, such as accumulated pitch error in geometric error. Excited by force, axial deflections directly affecting were studied based beam theory. By experiments, was predicted with 96% confident interval, tool number depth found to be significant terms. Tested under increasing speeds, rise of workpiece both decreased obviously. Thus higher speed could improve precision full-length screw.
