In the field of processing and manufacturing industry, what we often call machining is a process of changing the overall dimension or performance of the workpiece with processing machinery.

The production and processing process is divided into cold processing and hot processing according to the temperature state of the workpiece to be processed. 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.

Cold and heat treatment is often used in the assembly process of mechanical equipment. 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 wheel outer ring of the train is also sleeved on the substrate by heating, and its firmness can be ensured when cooling (this method is still applied to the transfer process of some parts).
