[0002] Lathe machining is a part of mechanical machining, and mainly has two machining forms: one is to fix a lathe tool to machine a workpiece that is not shaped in rotation; the other is to fix the workpiece to perform precision machining through high-speed rotation of the workpiece and transverse and longitudinal movement of the lathe tool (tool holder). Numerical control lathe machining is usually composed of a control system, a servo system, a detection system, a mechanical transmission system and other auxiliary systems. The material used for lathe machining is usually easy-to-cut steel and copper. The easy-to-cut steel contains a high content of sulfur S and phosphorus P.
