Numerical control technology is the power source of intelligent manufacturing system, which is equally important in industry as the mold with the title of "mother of industry". Numerical control technology integrates mechanical manufacturing, automatic control, microelectronics and information technology. In fact, it can be said that it is CNC machine tool technology.
If the numerical control technology is simple, it is the digital control technology, which mainly controls all kinds of machine tools, such as milling machine, lathe, machining center, etc. The real NC expert should know NC process programming, fixture selection, tool selection, internal PLC of NC machine tool, internal parameter setting, circuit maintenance and adjustment, hydraulic system of machine tool, etc. So numerical control is a technology involving many aspects.
So how important is numerical control technology? For example, we can't even surpass many foreign high technologies in theory, but we can't make them. In the field of aircraft engine, even if foreign manufacturers give us engine drawings, we can only stare at them. After all, our numerical control technology is not up to the level of our machining center The precision and roughness of the parts can not meet the requirements. Ultra high precision machining center belongs to international control, part of the game of big countries, and will not easily spread to China.
To speed up the transformation and upgrading of China's manufacturing industry, improve quality and efficiency, numerical control technology is an unavoidable obstacle. At present, it is still a long way from the world's top level.
At present, numerical control technology is studied as a compulsory course in some undergraduate colleges, and the Mechanical Department of Higher Vocational College also has the major of numerical control technology, but the numerical control talents still can't keep up, because numerical control needs to practice and operate the machine, but it doesn't have great significance to operate the lathe, and a good machining center, which starts with 5 million yuan, is not easy to give all students long-term practice So at present, although there are many people learning CNC technology, few people are actually familiar with CNC machining center. There are contradictions and difficulties, so we have to make greater determination to learn numerical control well
