Digital manufacturing process

However, the use of computers to transform the production equipment of enterprises is actually much earlier than the management information system. In 1952, the second year of the invention of commercial electronic computers, a company in the United States designed a CNC device and developed the first three-axis CNC milling machine. Although this milling machine is very large and costly, it opens up a new era of digital control. In 1958, the United States developed the first machining center. This means that the era of computer-changing manufacturing has officially kicked off. Subsequently, with the invention of the first micro-processing chip, various and hundreds of millions of embedded systems began to be embedded in various equipment and various products. The manufacturing industry began to move toward the era of computer control centered on digital manufacturing technology, which was called mechatronics at the time. The idea of "mechatronics" is not entirely at the essence of the problem, that is, computer control.


It can be seen that computer systems have long given intelligence to various manufacturing equipment. If you follow the definition of the previous intelligence, then the issue of intelligent manufacturing can be said to have been proposed very early. In the process of transforming the entire informationization industry, the industrial software has supported the development of enterprise digitalization and played a very important role.


Recently, TV stations have a seminar on China's manufacturing industry. Among them, the question "What else can't be manufactured in China's manufacturing industry?" has raised ten aspects, but no mention of industrial software. As everyone knows, China's manufacturing industry ranks first in the world, accounting for 20% of the world's manufacturing industry. However, China's industrial software is now more than 90% dependent on imports, a little more complicated, not domestic. Moreover, the market share of China's industrial software accounts for only 1.7% of the world's industrial software market share. A 20% manufacturing powers account for only 1.7% of the total, which is enough to show that the "physique" of Chinese industry is too weak. It seems that there is still a big deviation in the understanding of this issue.


In fact, as early as the 1970s, we can see the digitalization of the transformation of traditional industries flourished. Especially in 1974, after the fifth generation of computer numerical control devices using micro-processing chips and semiconductor memories was successfully developed, from the perspective of production equipment, the development was very rapid. In terms of CNC machine tools, from one axis to three axes to five axes to seven axes, it has revolutionized the industrialization based on information technology. There are also a variety of computer-aided systems, from auxiliary drawing CAD, to computer-aided engineering simulation CAE, to computer-aided manufacturing CAM, etc., which have had a profound impact on the modernization of manufacturing, completely changing the industrialization of modernization. Awareness.


Later, with the development of computer technology, full three-dimensional digital and digital simulation appeared. Industrial digitalization is moving towards the high end. From the start of the order, to the final product delivery, the entire process relies entirely on the control and support of computer software.
