One is to look at it from a micro perspective
Compared with traditional machine tools, vertical cnc machine has the following highlights. These advantages are all derived from the power of the computer in the CNC system. It can complete complex parts such as curved and curved surfaces that cannot be processed by traditional machine tools.
1. The computer has superb computing capabilities. It can instantly and accurately calculate the amount of movement that each coordinate axis should move, which can be synthesized into a complex curve and surface. It can realize automatic processing, and the automation is flexible, and the efficiency is 3 to 7 times higher than that of traditional machine tools.
2. The computer has storage and storage capabilities, so it can memorize and store the input program, and automatically execute it in the order specified by the program to achieve automation.
3. The CNC machine tool can automatically process another kind of workpiece by changing only one kind of program, so as to realize the automation of single and small batch production, so it is called "flexible automation".
4. The workpiece has high machining accuracy, small size dispersion, easy assembly, and no need to "repair". It can realize the concentration of multiple processes and reduce the frequent transportation of parts between machines.
5. It has multiple self-adjusting functions such as automatic alarm, automatic monitoring, automatic compensation, etc., so as to realize long-term unattended processing.
The above-mentioned advantage is unimaginable by the predecessors, and it is also an extremely significant breakthrough. In addition, FMC (flexible manufacturing cell), FMS (flexible manufacturing system) manufacturing cell), FMS (flexible manufacturing system) and CIMS (computer integrated manufacturing system). Numerical control technology has become the core and basic technology of manufacturing automation.
Second, it is necessary to carry out macro reforms
From a macro perspective, the military and civil aircraft industry in industrialized developed countries have already applied CNC machine tools on a large scale in the late 1970s and early 1980s. In essence, the use of information technology to carry out technological transformation of traditional industries (including the military and civil aircraft industry). In addition to CNC machine tools, FMC, and FMS, in the product development process, in addition to the implementation of CAD, CAE, CAM, virtual manufacturing, CIMS and other aspects, the implementation of MIS (MIS). And add information technology to the products it produces, including artificial intelligence. Because of the use of information technology, foreign militaries have carried out in-depth transformations in the civil aircraft industry (called informatization), and ultimately their products have greatly improved the competitiveness of their products in the international military and civilian markets. Compared with developed countries, the transformation of traditional industries by information technology is about 20 years behind. For example, in my country's machine tool ownership, numerically controlled machine tools (NC) accounted for only 1.9% in 1995, and Japan had reached 20.8% in 1994. Therefore, a large number of mechanical and electrical products are imported every year. Therefore, the necessity of CNC transformation of the machine tool is explained in a macroscopic view.
