Machinery parts is namely machine parts, it is basic components of machine.
Since the present of machine, the corresponding mechanical parts appear. But as also be a discipline, machinery parts separated from the mechanical structure and mechanics. With the development of mechanical industry, new design theory and method, new materials, new technology all appear one after another, then machinery parts entered a new stage of development. Theories such as finite element method and fracture mechanics, elastic hydrodynamic pressure lubrication, optimization design, reliability design, computer aided design (CAD), entity modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology has been gradually used in the research and design of machinery parts. Better combination of a variety of disciplines, combination of macro and micro to search new principle and structure, more dynamic and precise design, more efficient use of the electronic computer, the further development of design theory and method, is the important trend in the development of the discipline.
