Metalworking is a technological process of cutting or surface plastic deformation of metals and their alloys. In metalworking, the shape and dimensions of the metal are changed, the parts are given the desired shape using one or more metalworking methods. The reliability of any production, any metal structure depends on the quality of metalworking. Metalworking is understood as a set of technological processes that change the size, shape and other characteristics of metal blanks. Conditional classification of metal processing technologies: casting, machining (by cutting and pressure), thermal, welding, electrical, artistic.
