Mechanical precision machining is a kind of machining, but it is precision machining. With the development of the industry and the continuous changes in demand, the precision machining has changed a lot, its classification is more and more, its direction is more and more The finer it is, the more specialized the direction is. With the development of science and technology, its technology is also continuously improved, and the quality and accuracy of processing are also getting higher and higher. The development of science and technology and the economy has felt the direction of close mechanical development.

Since the emergence of machinery, there have been corresponding mechanical parts. But as a discipline, mechanical parts are separated from mechanics and mechanics. With the development of the machinery industry, the emergence of new design theories and methods, new materials and new processes, mechanical parts have entered a new stage of development. Theories such as finite element method, fracture mechanics, elastohydrodynamic lubrication, optimization design, reliability design, computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology, have gradually developed For the research and design of mechanical parts.

Better realize the integration of various disciplines, realize the combination of macro and micro, explore new principles and structures, use more dynamic design and accurate design, make more effective use of electronic computers, and further develop design theories and methods. An important trend in the development of this discipline.

Therefore, in the future, mechanical precision processing will become more and more comprehensive. It is no longer pure mechanical processing. It is combined with high technology, but it will play its role. Especially the digitalization of processing has made a qualitative leap in its development. It will become an important science in the future, serving industrial development.
