[0002] Machining refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. In the production process, any process that changes the shape, size, position and properties of the production object to make it a finished product or semi-finished product is called a process.
