[0002] Precision machining is a process of using machining machinery to change the shape, size or performance of a workpiece. According to the temperature state of the workpiece being processed, it is divided into cold working and hot working. Generally, processing at room temperature does not cause chemical or physical changes in the workpiece, which is called cold working. Generally, processing at a temperature higher or lower than room temperature will cause chemical or physical changes in the workpiece, which is called hot working. Cold working can be divided into cutting and pressure working according to the processing method. Common hot working methods include heat treatment, forging, casting and welding. Fixtures are needed in precision machining.
