Chapter 797

"Cloud boy, where have you been these days? Now the whole project stopped because you weren't there... "Finally, Yunfei went to Hal machine tool factory in the northeast.

In order to get research funds from the state and reduce some technology development costs, the world's largest turn milling composite machining center project led by the 91 research institute must be completed within the specified time.

Otherwise, even if they have the strongest technical strength, the state will not contract the development projects of these heavy equipment to the 91 Research Institute. Directly disqualify them.

What's more, this project was originally obtained by the second leaders who had retired under the threat of cloud and non.

If the production and commissioning of the equipment cannot be completed on time, it will affect the subsequent water turbine processing, thus affecting the power generation of the first unit of the whole Three Gorges project, the bosses who were waiting to clean up Yunfei will never be polite.

This is a chance to send them to the door.

What's more, the factory director of Wuhan Heavy Machinery has been promoted to the Ministry of machinery industry. It's impossible if we don't hold a grudge against the 91 Research Institute for robbing them of such a large project. His even, even to a large extent, is the above compensation for the old machinery factory established since the Westernization Movement.

There are people on it. It must be easy to do the project, isn't it?

Therefore, after knowing that there was something wrong with the R & D Progress of the super heavy turn milling composite machining center here, Yunkai had to rush to deal with it.

He is not a professional, but he knows the structure of the equipment better than these professionals.

At that time, he personally saw the world's largest metal cutting machine tool. When he was shocked by the power of mankind, he wanted to operate the equipment one day.

He never thought that this equipment could be produced from his hands.

"I said to you guys, you are professional. I'm just a lucky boy. This project stops and waits for me. Have we lost tens of millions of money?" Yun Fei said painfully.

He was sure that if he didn't finish it on time, pan Zhigao and Yang Qing would definitely put all the responsibility on themselves.

These two guys will never talk about Jianghu morality.

"President Yun, you put forward the design concept of this scheme. Although we are responsible for implementing these technologies, you can't ignore the problem now, can't you?" Huang Chaohai, who has been promoted to chief engineer of Hal heavy industry, said bitterly to Yun Fei.

This project has never been paid attention to except when Yunfei beat the table with the second leader of the university to grab the project at the beginning. This is different from his performance before the project.

This project is related to a long-term research project in the future.

The 91 research institute does not lack the national research funds, but they are short of Hal heavy industry!

"Come on, I said you too. Is it necessary for so many people to come to the airport to meet me? I have to keep a low profile now, or the old man will have to hit me with his crutch again. I deserve it... "Yun feidan said painfully.

Originally, he meant to go to Hal heavy industry directly after getting off the plane without notifying the people of Hal heavy industry, but Jiang Jianxing still informed them.

"You killed yourself. You can't blame anyone. Who told you to make a titanium cane for the old man yourself? If you get a stainless steel or high manganese steel, can the old man still carry it? " Yang Qing wants to show off to Yunfei.

The grandson is showing off his relationship with the old man.

"Yes, your boy killed himself. No wonder others." Pan Zhigao also rolled his eyes.

It is estimated that this boy is the only one in China.

The crutches he gave to the old man were processed with the equipment developed by their own Jiuyi heavy industry, and many patterns were carved on them, which is the first souvenir processed by their four-axis machining center. It is of great significance to the whole CNC machine tool industry in China and should be placed in the industrial museum, But the boy gave it to the old man.

For such things, they can only look jealous.

These enterprises hate him even more.

Just because the old man leaned on this stick, he scolded the leaders of the Ministry of machinery industry and other relevant departments.

"Come on, stop bullshit. Let's go to the scene and have a look. I'm not professional, and I'm expected to put forward some professional opinions. What is the biggest problem now? " Yun Fei is too lazy to entangle with them.

Entanglement is not good for yourself.

These shameless old guys have blackmailed themselves for several times.

"The main problem is the control. We design each part according to the concept you put forward, and then Mr. situ and his assembly design. There is no problem in theoretical verification, but now there is a problem after production. The main problem is that the turning and milling function cannot be synchronized in the processing process..." Huang Chaohai is a master of technology, Have more say than others.

These days, situ Heyun and his colleagues have been staying in the workshop and conducting various experiments to solve problems.

"Control out of sync? Isn't it easier to control this thing than five axes? Moreover, there will be no big problem as long as the hydraulic system and pneumatic system are solved. " Yun Fei frowned.

Although he has not engaged in technology for many years, these theoretical things come at once.

I used to have a good foundation. In recent years, I often go to the production and test workshop of the 91 Research Institute to kill time. Speaking of theory, it is absolutely one set.

"What robot network neural unit control node?" Everyone on the bus was confused.

"Well, I didn't put this forward before the design?" Yun Fei was stunned.

The crowd was even more stunned.

"Have you asked this question again? Mr. Yun, can't you remember wrong? " Huang Chaohai has an impulse to go crazy.

When did Yunfei propose to their project team the design of control node using robot network neural unit? Robot technology is the core technology of the 91 Research Institute. It is strictly confidential to them.

"How could it not have been mentioned? How could I remember wrong? I clearly remember that when you discussed it, you proposed that this turning milling compound machining center can be regarded as a flexible manufacturing system? In this system, each moving part is regarded as an independent whole, and then a separate industrial control chip is used to control the moving part, just like a CNC machine tool. The industrial control chip is the CNC system... "Yun Fei absolutely remembers what he said.

Each of these heavy equipment requires hundreds of industrial control chips.

This is the most basic and common application of robot network neural unit.

Even those people of Wuhan heavy industry can think of this. Situ Heyun and Sun Lin, who deal with Deng Lanqing, who is engaged in robot projects every day, can't they not know this?

"What a fart! Mr. Yun, you just said that you should separate the heavy-duty milling parts and heavy-duty vehicle processing mechanism, and then use the CNC system to control the assembly... "Hearing Yun Fei's words, Huang Chaohai couldn't help but burst into foul language.

Yun Fei never said such a thing.

After he just put forward a design idea, he ignored it, and then they were responsible for their own parts. Finally, Sun Lin and them carried out the assembly design. After the design was completed, they used the supercomputer of 91 Research Institute to model, and then simulated the operation. After confirming that there was no problem, they began production.

Otherwise it wouldn't be the problem now, would it?

The whole project stopped for half a month!

"I really didn't say that?" Yunfei was also a little uncertain whether he had said it or not.

Over the years, he has done a lot of things, and he has used his brain too much. It is easy to forget some things or remember some things wrong. It was what he planned to do at what time. In the end, even if he didn't do it, he would subconsciously regard what he imagined as done

"Did you say that?" Yang Qing and pan Zhigao stared at Yun Fei in unison.

When they first discussed this matter, they were all in the 91 Research Institute in Chengdu. Yunfei never raised this question.

In the area separately divided in the assembly workshop of Hal heavy industry, hundreds of square meters are separately assigned to this world's first metal cutting machine tool with a final total weight of more than 700 tons.

The production of the main body has not been completed. The highest part is more than ten meters high, and the heaviest large casting also weighs hundreds of tons. Thanks to Beifang heavy industry and Hal heavy industry, which are engaged in this project, are companies specializing in the production of super heavy equipment. Otherwise, they will have a headache just because of the design in large castings.

People engaged in mechanical materials know that the larger the casting, the more difficult it is to discharge the air inside after pouring molten iron. If the air remains inside the parts, it will form casting defects, huge pores and sand holes, and even directly scrap the large casting.

There are not many companies in the world that can produce hundreds of tons of castings.

However, in China, at least five companies can produce such castings.

Many large castings of the world's largest machining equipment have been produced. Although they have not been finished, another part of the assembly workshop is also some super heavy equipment rarely seen outside for assembly convenience.

Even the super heavy horizontal lathe with a load of more than 250 tons built by Hal heavy industry with the help of xinkaixing is placed in this workshop. After all, that thing is mechanical transmission, manual operation and numerical control transformation, which will be in the future.

The entire workshop of more than 3000 square meters has no more than ten sets of equipment.

There are no more than 50 front-line production workers, but there are hundreds of technical engineers and auxiliary personnel.

Besides, when these heavy parts weighing tens or hundreds of tons are clamped and aligned, it is impossible without the help of more than ten people. In addition, some mechanical equipment must be used. No matter how powerful a person is, he can't pry dozens or hundreds of tons of heavy parts, can he?

There are at least three operators in each shift of each equipment. The larger the equipment, the more operators. These guys can definitely die when they're right. But when these equipment are processed, these workers can be idle. Because of such parts, one-time clamping may take a month or even months of machining

Yunfei was also confirmed by situ Heyun and sun Lin. he really didn't say this way of control.

Yun Fei was stunned.

Is there really something wrong with his memory?

"Xiao Yun, I think you should go to the hospital and have a good check. You often record some things that haven't happened as things that have happened..." Sun Lin still knows the symptoms of Yun Fei.

"It's all right, Mr. Sun. I was under too much pressure in the past. I basically didn't care about the company at this time. I was on vacation. There would be no problem if I had a rest for a period of time..." Yun Fei shook his head indifferently.

I know my own things.

No one can know how much he has paid for the development of these industries.

Every day during the day, his mind constantly recalled some major events in these industries in his original world, and even he had to think about how to avoid some abnormal situations in his company.

Even in the evening, he was thinking about the company.

After thinking about it, I infer all kinds of situations in my mind, and then tell Jiang Jianxing these things and let him operate them.

It is precisely because he is thinking about these things every day in his mind, but he can't get peace when he comes home at night, and his head will be blown up by several women. How can he not be weak?

This is also the fundamental reason why he decided to have a good rest this time.

"In general, we also modified according to this design concept, but the more industrial control chips installed, the greater the problem of synchronization. In this way, the error in processing is very large, and even several millimeters of error can be generated at the maximum. Although the accuracy requirements of the water turbine are not high, the processing error of one or two millimeters is acceptable, But it's almost impossible to make some heavy parts with high precision... "Situ Heyun's white eyebrows frowned tightly.

China has always been a weak point in this regard.

Those foreign companies will not tell them the control methods of these core technologies.

Everything can only be explored by yourself.

Just as the old man said in those years - if you touch a stone to cross the river, you may drown if you don't pay attention.

"The control chips of each part are connected to the main control line in parallel. In this way, the farther the components are from the control center, the more serious the delay phenomenon will be. In theory, it only takes a few tenths of a millisecond or even microseconds, but when it is amplified in the machine tool action, these delays are also fatal... "Cao Zhijiang has become the chief engineer specializing in numerical control system in the automation control of Jiuyi Research Institute. He is also here to deal with this problem these days.

There is no way to avoid the defect of the control system.

"This is because of the performance problem of industrial control chip?" Yun Fei asked suspiciously.

This turn milling compound machining center uses the 64 bit industrial control chips newly developed by the 91 Research Institute. Theoretically, these industrial control chips are enough to support this turn milling compound machining center that does not require too complex control mode. g

The country also knows the domestic technology, but it was able to accept CNC equipment at the beginning.

The great reason why the 91 Research Institute can seize this project is that the full CNC scheme they put forward is not just caused by cloud non threat leaders.

"The biggest problem is the performance of the chip and the performance of our control system. Compared with those small machining centers, turning milling meets the needs of the machining center to control more things. It is just a hydraulic system, which is a huge control project, as well as various circuits, and the control of machining actions... "Cao Zhijiang nodded.

The 138 bit chip has just begun research, and no experimental products have been developed.

"Since the chip performance is insufficient, take one or more control chips at each node to form a control cluster at the position of each node, and finally use the numerical control system to control the assembly?" Yun Fei put forward his own views.

"We have tried and simulated, and doing so will make the delay in the control process slower..." Sun Lin shook his head and said.

Cloud can't think of a way. They can't think of a way, can they? Otherwise, all these years will be in vain.

"Try the bridge connection method. The CNC system does not process the details of the processing process. The processing of these details is directly handed over to the industrial control chip controlling each moving node for calculation. In this way, the operation pressure of the system is dispersed to each industrial control chip. The system only needs to issue the work instructions of each node... "Yun Fei's words immediately brightened everyone's eyes.

Industrial control chips are rarely responsible for calculation, but only assist the CNC system to control various actions.

The idea put forward by the cloud is reversed. The most powerful CNC system is only auxiliary, and most of the main computing and control functions are transferred to the industrial control chip at the node.

"Such a scheme is fully achievable. When controlling various actions of the previous instruction, the next instruction starts to prepare the instructions that will have actions. Once the action of the previous instruction is realized, the action of the next instruction will be run immediately. In this way, the problem of delay was solved in the initial preparation time... "Hearing Yun Fei's words, Cao zhijiangdun clapped his hands and said excitedly.

They can actually solve these problems, but it takes time.

At present, their thinking has been greatly limited, and Yunfei has seen a variety of CNC machine tools, even military grade ultra precision CNC equipment.

In fact, these ideas were not created by Yun Fei, and he just used the doctrine of taking.

Stole the theory that came out after countless tests abroad.

Without carrying out experiments, it has directly become the scientific research achievements of the 91 Research Institute

In the early days of the 91 Research Institute, 50% of the research results of CNC machine tools were plagiarized by Yunfei. If people didn't know these things and regarded Yunfei, a young demon, as a big winner in this industry, they wouldn't expect Yunfei to solve their problems anyway.

Every time Yunfei puts forward some ideas, they can break their thinking limitations.

This is why Yun Fei is respected by these academicians of the Chinese Academy of Sciences in the whole research institute.

Yunfei did not receive the most formal university education, but received the most traditional and professional mechanical and electronic circuit training. Their research institutes have shown a more solid foundation than those graduate students and even doctoral students.

The stronger the foundation, the easier it is to grasp the direction and make a breakthrough.

In private, when Sun Lin and situ Heyun chatted with a group of old brothers, they lamented countless times that Yunfei didn't engage in technical research, which was the loss of the whole country.

But they don't know that Yun isn't just an armchair Zhao Kuo!

"Boy, you said you didn't do it with good technology and ran to start a company!" Huang Chaohai feels deeply about this matter.

So many academicians who enjoy the state special allowance can't solve the problem. Yun Fei just went to the scene and asked some questions, and then put forward a solution. This makes them very dissatisfied with Sun Lin, who pressed the treasure to Yun Fei, a young man. He can only lament that the back waves of the Yangtze River push the front waves. These front waves were photographed and killed on the beach by the boy.

"I just want to be the most ordinary technical engineer, but it costs money to do research! In those years, my grandfather lived like that in order to make their own CNC system in China. In the end, they completed the theoretical research and carried out the experiment because they didn't have tens of thousands of yuan of research funds... "Yun Fei said lonely.

Huang Chaohai was really ready to say something, but he was pulled by Pan Zhigao around him.

Yun Fei is very upset that these national scientific research institutes have a large amount of scientific research funds without results. This matter must not provoke this boy.

A relatively small turn milling compound machining center was used for experiments, which soon confirmed the feasibility of Yunfei's design.

This let everyone breathe a sigh of relief.

"Cloud boy, can you share your robot technology with us? I found that this robot technology has a great relationship with this CNC machine tool technology... "Pan Zhigao now wants to get rid of 91 heavy industry and work alone, but he is embarrassed to talk to the cloud about technology.

"Don't even think about it. We spent a lot of money on these technologies. NIMA, your research budget of Hal heavy industry last year was more than 100 million? How many results have been achieved? Want to fool those guys at the top with our technical achievements? You will die of this heart! " Yun Fei despised the old thing.

At first, I was going to pull them to work together to reduce my risk, but these guys don't agree. Now they want to share technology. Don't even think about it!

"Let's pay for it!"

"You can't give money!"
