There are four huge machine tools in the whole workshop, lathes, grinders, cutting machines and milling machines, in China, lathes can not be described as huge, such as Sun Mingfan's "Gemei" air-conditioning factory also has these four kinds of machine tools, each of the largest is only more than 500 catties, it is considered the top machine tool in China, Sun Mingfan also spent a lot of money in order to buy these equipment, but here, each lathe is two or three tons heavy, standing there like a tank.

Of course, it is not that the machine tools in the United States are bulky, but that these machines have already adopted a numerical control system.

In 1952, the Massachusetts Institute of Technology installed a set of experimental numerical control system on a vertical milling machine, and successfully realized the simultaneous control of the movement of three axes, this CNC machine tool is known as the world's first CNC machine tool, because the CNC system at that time used an electron tube, large volume, high power consumption, each of which weighs four or five tons, so in addition to the use in the military department, it has not been popularized in other industries.

After 1960, point-controlled CNC machine tools have developed rapidly. Because the CNC system for point control is much simpler than the CNC system for contour control. Therefore, CNC milling machines, punching machines, and coordinate boring machines have developed in large numbers.

Britain first connected several CNC machine tools into a flexible processing system, which is the so-called flexible manufacturing system, and then the United States, Europe, Japan and other countries have also been developed and applied. After 1974, with the rapid development of microelectronic technology, microprocessors were directly used in CNC machine tools, so that the software function of CNC was strengthened, and it developed into computer numerical control machine tools.

The machine tool of Professor Claire's laboratory is the use of the most advanced CNC system three-axis linkage machine tool, coupled with the workpiece automatic loading and unloading and monitoring and inspection device of flexible manufacturing, has reduced the manual participation to a minimum, more than 1,000 square meters of workshop only a dozen people in the operation, they wear clean work clothes, some people are electronic control of the machine tool, some people will check it from time to time, but they are not directly involved in mechanical manufacturing.

This kind of scene can not be seen in the domestic workshop, there are all people, everyone is covered in oil stains, and there is basically no human appearance after a day's work.

However, it is now the eighties, the level of CNC machine tools and later generations can not be compared, the main thing is that the CNC system is still very simple, of course, this simplicity is compared with thirty years later, in this era is already the most advanced.

Liu Lang saw the CNC system processor, which was engraved with the label "Intel", obviously, this is a processor developed by Intel Company, but these processors cannot be called CPUs, they can only be called microprocessors.

A microprocessor is a central processing unit composed of one or a few large scale integrated circuits. These circuits perform the functions of control components and arithmetic logic components, compared with traditional central processing units, microprocessors have the advantages of small size, light weight and easy modularization, but microprocessors are not the CPU of computers, the two are both related and different, microprocessors are miniature, low power consumption, low frequency, The function is weak, mostly used in small electronic devices such as household appliances, etc., the CPU function of the computer is far stronger than the microprocessor, and the structure is also much more complex, so there are many companies that make microprocessors, but there are not many companies that can make computer CPUs.

Liu Lang has been paying attention to the computer market in the United States, in the past few months, this battlefield has begun to emerge enterprises that no one has heard of before, such as Microsoft, they have been listed in the early eighties, the market value reached its peak at the beginning of this year, there are one billion US dollars, and VIE and IBM are naturally incomparable, but it is also an emerging computer company, the stock market crash in June made them fall by nearly 30 percent of the market value, which can be described as a heavy loss, but two months after VIE announced the image processing program, Microsoft took the lead in releasing it"Microsoft indos2.0" control system, this system is much more powerful than the original "Microsoft indos1.0" system, suddenly attracted the attention of the market, Wanan specially bought a set of research, found that the writing program of this system has appeared the latest computer language program developed by Wanhe, that is, the other party has begun to decipher.

There is no way for this kind of thing, computer languages are universal, only one person successfully writes, then it will soon be popular, there is no way to stop it, VIE immediately began to accelerate the development of the PS system, half a month later, the computer installed this system officially came out, the word processing function is much more powerful than "Microsoft indos 2.0", this new set of "PS" The system detonated the United States again, many people think it is incredible, before the VIE company has been steady and steady, decades of stability, how can it suddenly launch two powerful software, different from the previous program in half a year?

But in any case, VIE immediately stirred up the world's computer market with such a force.

Intel also showed its edge at this time, and they joined forces with IBM, and the personal computer business became a top priority, and began to develop more powerful personal computer chips.

This situation is very different from Liu Lang's previous life, in the previous life, after the appearance of personal computers, VIE was directly eliminated, IBM was also hit very hard, Microsoft and Intel were the only two winners, and then the cooperation between the two companies swept the world, and finally forced IBM to unite with them, but after the union, IBM has become the weakest of the three, and it has fallen off the altar.

But now it's different, VIE is not "dead", and is still ahead of the world in chip design and software development in Liu Lang's efforts, and this time it has become the target of public criticism, and the gun is shot in the head, this sentence is also applicable in the United States, and now whether it is IBM, Intel or Microsoft, VIE is the number one target.

The situation of Wan'an Company and Liu Lang's previous life have completely changed a hundred and eighty degrees, this is not to say how powerful Liu Lang is, it is completely a change between thoughts, after all, the hardware of Wan'an Company is there, the mistake is that he did not see the trend of history, as well as the stubbornness of Wan'an itself, if there were no these two obstacles, they would not have lost so badly in Liu Lang's previous life, and there was Liu Lang's "guiding light" in this life VIE inadvertently came to the forefront of the big wave of computer development, a big step ahead of other companies, this situation even Wan'an himself was convinced, and Liu Lang was degraded by a strategist, he was a great prophet.

However, this does not mean that VIE will be unbeatable, such as Intel and Microsoft are a bunch of genius programmers in companies like Intel, although you are now ahead of them, but you can't say that you will always be ahead, the computer industry is like this, a little slack is likely to be overtaken, but Liu Lang believes that with his existence, at least VIE will not take a detour.

Of course, Liu Lang is a layman in the chip and computer industry, he doesn't know much about technology, he only knows the development of the general trend, which is enough, and he is also ready to plan, in the future, VIE must develop the microprocessor of CNC machine tools, with their help, at least in the digital control system can achieve the world's advanced level.

CNC machine tools are the trend of the development of the machinery industry, now the country's industrial machinery is still in the "original manual" stage, the need for technological upgrading, CNC system Liu Lang do not worry, the rest is the technology of machining, Liu Lang in Claire's laboratory is mainly for the study of this knowledge.
