Precision Machining And Ultra-precision Machining Are The Foundation And Key Of Advanced Manufacturing Technology

At present, in the field of manufacturing automation, a lot of computer-aided manufacturing software has been developed, such as computer-aided design (CAD), computer-aided engineering analysis (CAE), computer-aided process design (CAPP), computer-aided machining (CAM), etc. , collectively referred to as Computer Aided Engineering (CAx), such as Design for Assembly (DFA), Design for Manufacturing (DFM), etc., collectively referred to as Design for Engineering (DFx); also carried out computer integrated manufacturing (CIM) technology, production Models such as lean production, agile manufacturing, virtual manufacturing, cleaner production and green manufacturing are all very important and necessary, and represent an important aspect of current high-tech manufacturing technology. However, as the main battlefield of manufacturing technology, as the actual manufacturing of real products, it must rely on precision machining and ultra-precision machining technology. For example, the development of the computer industry should not only be based on software, but also on hardware, that is, integrated circuit chips. It should be said that at present, the manufacturing level of my country's integrated circuits constrains the development of the computer industry. The "two-millimeter project" of the automobile manufacturing industry proposed by American manufacturing engineering researchers makes the quality of automobiles catch up with the level of Europe and Japan, and the measures in it are all real manufacturing technologies.
