Machining is a process of using machinery to change the appearance dimension of workpiece or performance.
According to the processed workpiece in the temperature condition, it can be divided into cold working and hot working.
General processing at room temperature, and not causing the chemical and phase change of workpiece, we call it cold working. Cold working according to the difference of processing methods can be divided into cutting machining and pressure working.
General processing in higher or lower than the normal temperature condition, causing chemical or physical phase change of workpiece, we call it hot working. Hot working common contains heat treatment, forging, casting and welding.
