Precision mechanical processing involves altering the shape, size, or properties of workpieces using machining tools. Based on the temperature of the workpiece during processing, it is categorized into cold working and hot working. Cold working, which typically occurs at room temperature, does not cause chemical or phase changes in the workpiece. Hot working, on the other hand, involves processing at temperatures above or below room temperature, which can lead to chemical or phase changes in the workpiece. Cold working can be further divided into cutting and pressure working based on the method used. Common forms of hot working include heat treatment, forging, casting, and welding.
