Machining: machining is a process of changing the overall dimension or performance of a workpiece with a machining machine. According to the temperature state of the workpiece to be processed, it is divided into cold processing and hot processing. Generally, it is processed at normal temperature without causing chemical or phase changes of the workpiece, which is called cold processing. Generally, processing above or below normal temperature will cause chemical or phase changes of the workpiece, which is called hot processing. Cold working can be divided into cutting and pressure machining according to the difference of machining methods. Heat treatment, forging, casting and welding are common in hot working. In addition, cold and heat treatment is often used during assembly. For example, during bearing assembly, the inner ring is often cooled in liquid nitrogen to shrink its size, the outer ring is properly heated to enlarge its size, and then it is assembled together. The outer ring of the wheel of the train is also sheathed on the substrate by heating, and its firmness can be ensured when cooling (this method is not known whether it is still used).

Mechanical processing includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming and metal plate bending
