Have you heard of the origin of precision parts
Since the emergence of machinery, there have been corresponding mechanical parts. Precision parts processing But as a discipline, mechanical parts are separated from mechanical structure and mechanics. With the development of machinery industry and the emergence of new design theories and methods, new materials and new processes, mechanical parts have entered a new stage of development. Finite element method, fracture mechanics analysis, elastohydrodynamic lubrication, optimization design, reliability design, computer-aided design, system analysis and design methodology have been gradually used in the research and design of mechanical parts. It is an important trend for the development of this discipline to better realize the integration of multiple disciplines, to realize the combination of macro and micro in the processing of precision parts, to explore new principles and structures, to adopt more dynamic design and precise design, to more effectively use electronic computers, and to further develop design theories and methods.
An assembly unit is a part of a machine, which is composed of several parts assembled together. In the process of mechanical assembly, these parts are first assembled into components (component assembly), and then enter the general assembly. Some components (called sub components) are assembled into larger components with other components and parts before entering the general assembly. A larger part assembled by several parts and having independent functions is called an assembly in the automobile and some other mechanical industries.
