The Red Era, the Opening University Speech

Chapter 289 3+2 CNC Milling Machine
Professor Bai didn't even rush to eat, and said, "Don't worry, although there are certain difficulties in the development of synchronous dynamic random access memory, we can overcome them at present."

"That's good. I knew you guys could do it, Professor Bai." Li Mu gave a thumbs up.

Just as he finished speaking, two people walked in from outside the cafeteria - Professor Zhou and Professor Lu from the data server development team.

Li Mu quickly spoke to Professor Bai and asked him to hurry up and eat.

Then he called Professors Zhou and Lu to inquire about the construction of the data server.

"Overall, everything has gone smoothly. However, the network interface created by our current technology can only handle a small number of network requests and cannot handle a large number of network requests," said Professor Zhou.

Network interfaces are the pathways that enable data servers to communicate with other devices and networks.

If this problem is not solved, then no matter how good their data server is, it can only serve a few computers in the end.

Li Mu pondered for a moment and said, "Well, go back to the network R&D team and find Director Wang, and ask them to work with you to develop a network interface card."

"Through this interface card, the server and computer can be connected."

Network interface card, also known as NIC.

This hardware is key for computers to communicate on computing networks.

He hadn't done it before because there was no computer network.

But now it seems that we still have to do it.

Even if the network cannot cover the entire country, it must at least cover the entire Kyoto.

"Okay, let's go now." Professor Zhou and Professor Lu immediately planned to turn around and look for Wang Shoujue.

Just as Li Mu was about to call them, Wang Shoujue and Wu Youxiang walked in together.

Seeing him sitting at the door, the two of them looked at him suspiciously.

Looking at Professor Zhou and Professor Lu standing by, he immediately understood.

"You, you really can't sit still. You said you would take a rest, but why are you running to the cafeteria to block people?" Wu Youhao taught him earnestly.

Li Mu didn't expect that he would be so unlucky to be caught red-handed. He smiled bitterly and said, "I just took advantage of the meal time to communicate with everyone."

"Okay, don't say anything. Just go home after dinner." Wu Youxiang waved his hand and said directly.

Wang Shoujue at the side also advised: "Have a good rest for a night before returning to the institute to continue your research work. Look at the bloodshot in your eyes, it hasn't disappeared yet."

"Thank you both directors for your concern. I'll keep it in mind." Although Li Mu didn't want to go back so early, he was still touched when he heard their caring words.

Well, I was planning to stay until 11 o'clock, so let's go an hour earlier.

But just as he was thinking this, a familiar figure suddenly walked in from outside the door.

After coming in, Wang Ya first greeted Wu Youxiang and the others, then glanced at Li Mu indifferently and said, "Have a good rest today. I will go home with you after dinner."

"Okay, I'll listen to you." Li Mu said helplessly.

You can disobey anyone, but you can never disobey your wife.

This reaction made Wu Youxiang, Wang Shoujue and others burst into laughter.

……

Had a good night's rest.

The next day, Wang Ya originally wanted to let Li Mu take a day off.

A phone call came from the Chinese Academy of Sciences, and the "ding-ling-ling" sound echoed in the living room.

Li Mu picked up the phone and heard Tang Yanjie's voice:
"Consultant Li, sorry to bother you. I know you're resting, but I can't wait any longer. After receiving the two plans you gave us, our Aviation Academy held an expert meeting overnight."

"Everyone agrees that your turboshaft engine design is highly feasible, and your research on modified double-base propellants is expected to promote domestic solid fuel research!"

"Therefore, I would like to invite you to come to the Institute of Aeronautics again to lead the development of these two research projects!"

His tone was full of excitement and excitement.

Now that the engine problem has been solved, the development of the Xuanniao-1 helicopter has become smooth sailing and there are no major problems.

It would take at most two years, or at most one year, to make Xia Country’s own helicopter!

There is also modified double-base propellant. Once successful, many of their research in the aerospace field will be able to achieve tremendous development.

"No problem. I'll wait for you to send a car over." Li Mu agreed without thinking.

After saying that, he put down the phone and turned back to look at Wang Ya apologetically.

Wang Ya returned to the room, took out a coat for him and put it on, saying, "Put it on. It's still a little cold. Take care of yourself."

"Okay." Li Mu grabbed her hand that was straightening his collar and nodded heavily.

……

Not long after, the car sent by the Aviation Institute arrived under the special building.

Li Mu took a car and went to the Aviation Institute again.

As soon as I arrived at the gate and hadn't gotten out of the car, Tang Yanjie and Wang Shicun came to meet me.

He said directly: "Dean Tang, Professor Wang, no need to exchange pleasantries, let's go directly to the conference room."

"Okay." Tang Yanjie didn't waste any words.

The three of them walked quickly across the open space of the research base and entered the meeting room.

The experts and professors who were arguing loudly inside immediately quieted down when they saw the three people come in.

I don't know who took the lead, but thunderous applause broke out instantly:

"That's amazing, Consultant Li. I didn't expect you to actually complete the design of the Xuanniao-1 turboshaft engine!"

"It is unique in the world that I can complete all the designs of a helicopter by myself!"

"We have also studied modified double-base propellants. If successful, it will have revolutionary significance for the development of our country's aerospace industry!"

……

The experts and professors applauded and expressed their admiration and amazement generously.

"Thank you for the praise, professors. It's just that the theory is feasible. The real test is to turn the theory into practice!" Li Mu said hurriedly.

You still need to be humble, otherwise people will inevitably think you are arrogant.

As soon as he finished speaking, a professor in his 50s came out and said, "Advisor Li, you are being modest. If it weren't for you, we probably wouldn't be able to make breakthroughs in these theories even if we spent several years working on them."

"That's right, especially for the research on modified double-base propellants, even Emperor M and Big Brother may not have done it so deeply!" Another professor in his thirties or forties followed suit.

These words won everyone's approval.

They all know very well that practice is the basis of theory.

However, without theoretical guidance in practice, we can only proceed step by step by trial and error.

The cost during the process is difficult to estimate, and if there is a mistake, all the previous efforts will be wasted. Therefore, the two highly feasible research plans of Li Mu are extremely valuable.

"May I know who these two professors are?" Li Mu looked at the two people who spoke and asked.

The old professor then remembered that he had not introduced himself yet, and said with a smile: "My name is Zhu Yajie, and I study the comprehensive utilization of combustible minerals in chemical industry."

"Cui Guoliang, who studies solid rocket propellants and engines." Another younger professor followed.

Hearing their names, Li Mu was slightly surprised.

One of these two people is the founder of the artificial petroleum discipline in the Xia Dynasty and the founder of new energy technology. The other is a big shot in the Academy of Engineering in later generations and an expert in the development of various solid propellants. Both of their achievements are very dazzling.

Zhu Yajie continued, "We, as well as many solid fuel experts behind us, all rushed here after learning that you, Consultant Li, had developed a modified double-base propellant."

"It's just a preliminary research plan. It's hard to say whether it will succeed." Li Mu then realized that there were at least half more people in the conference room than before.

Obviously, Tang Yanjie attached great importance to his plan after receiving it.

Zhu Yajie said:

“Whether it can be accomplished or not, at least after all of our tests, it is definitely feasible.”

"Advisor Li, I am convinced of your ability. I thought it was a bit of an exaggeration to say that you are the only winner of the first prize of the National Highest Science and Technology Progress Award."

"Now it seems that I was wrong. You deserve this first prize. Moreover, this award will attract worldwide attention because of you in the future."

He looked at Li Mu with admiration in his eyes.

Other experts and professors also nodded repeatedly.

Not to mention those who had just arrived, even those who had seen Li Mu many times before had their perceptions of genius refreshed.

Anyone who can stand in this laboratory was called a genius when he was young.

But it was not until today that they saw what true genius is.

Facing everyone's praise, Li Mu could only keep smiling and quickly change the subject:
"Professor Zhu, let's get down to business and start discussing the research."

"Okay, okay, then please ask Consultant Li to give us a comprehensive analysis of the design ideas and possible implementation plans for modified double-base propellants and turboshaft engines!" Zhu Yajie made a gesture of invitation.

Tang Yanjie standing by also smiled and gestured for Li Mu to sit on the main seat.

"Then I will talk about it briefly. I hope the experts and professors will give me some advice." Seeing this, Li Mu did not refuse and walked straight to the podium.

Reaching out and grabbing a blackboard, he continued while drawing:
"Let's talk about the turboshaft engine first. In terms of structure, my idea is to adopt a free turbine design."

“It consists of a 5-stage axial flow low-pressure compressor, a 1-stage centrifugal high-pressure compressor, an annular combustion chamber, a 2-stage compressor turbine and a 2-stage power turbine.”

"The combustion chamber is located between the compressor and the turbine. It is used to mix the compressed air with the fuel and ignite it to produce high-temperature and high-pressure combustion gas, which drives the turbine to rotate..."

……

Li Mu first briefly introduced the structure of T700/CT7.

Then he raised the most important difficulty - CNC milling machine.

He bluntly said: "With our current 3-axis CNC milling machine technology, it is almost impossible to achieve precision machining of turboshaft engine parts."

Xiaguo's CNC milling machine technology was invented in 58 and was jointly developed by China Europe International Business University and Kyoto Kitaichi Machine Tool Company.

Compared with the 52 years of invention time abroad, the difference is only 6 years.

However, after that, due to various reasons, CNC milling machines have not developed much, and most of them are imported from abroad.

It was not until the 21st century that technology slowly caught up and the research on 4-axis and 5-axis was completed.

"I'm afraid it's impossible to develop a new CNC milling machine in a short period of time." Wang Shicun frowned deeply.

Not only him, other experts and professors also looked embarrassed.

Li Mu smiled and said:

"It's actually very simple. Our country's current CNC milling machines still use electron tubes as their main components. By utilizing our technological advantages in semiconductors, we will soon be able to catch up with Emperor M."

"But this alone can only barely meet the development conditions. It would be best if we could develop a 3+2 axis CNC milling machine."

"You can also call it a pseudo 5-axis CNC milling machine. Although it cannot compare to a real 5-axis machine, it should still be much better than a 4-axis machine."

He didn't dare to think about the technical difficulty of 5-axis.

Even if we dare to think about it, we can't do it under the current conditions. We can only try to make a pseudo 5-axis.

"Consultant Li, what is the principle of this 3+2-axis CNC milling machine you are talking about? I seem to have never heard of it before?" Wang Shicun asked doubtfully.

The others also looked confused.

4-axis and 5-axis, even though Xia Country cannot produce them at present, it still has some knowledge of this technology.

A 3+2 axis CNC milling machine is simply unheard of!

Li Mu smiled and explained:
"It's actually very simple. The 3-axis machining method we usually talk about is machining by linear feed X, Y, and Z. The direction of the cutting tool remains unchanged along the entire cutting path."

“With the 3+2 axis, the cutting tool is fixed in an inclined position through two rotating axes, and then the processing is performed by feeding X, Y, and Z.”

“Finally, a static plane conversion programming software was used to realize the rotating plane work in space.”

After he finished speaking, everyone fell into long contemplation.

This 3+2 axis machining method uses positioning tools to perform machining at fixed positions, reducing tool path overlap and machining time.

There will also be shorter tools and closer machining distances.

In theory, it does help reduce manufacturing time and improve processing accuracy.

The only trouble may be that multiple tilted views are needed to cover the entire workpiece, which greatly increases the difficulty of processing.

"But even if it is a 3+2-axis CNC milling machine, I'm afraid our current technological level is not enough." Wang Shicun shook his head.

After the big brother withdrew a large amount of aid, Xia State's research on CNC milling machines also suffered a major blow.

It is already difficult to produce 3-axis CNC milling machines now, let alone the more powerful 3+2 CNC milling machines.

Tang Yanjie at the side could not help but remind him: "Advisor Li, why don't we take it step by step, starting with the 4-axis CNC milling machine, and move forward steadily."

My family knows their own affairs.

Don’t be fooled by the fact that Xiaguo has recently reported many major breakthroughs in the field of science in newspapers.

But in the final analysis, their foundation is still too weak.

In terms of basic scientific research strength and basic industrial strength, they are far inferior to Emperor M and Big Brother.

Wang Shicun and others no longer dared to think that they could catch up with the two in the field of CNC milling machines.

Not to mention the 3+2 CNC milling machine that even Emperor M and Big Brother have never made.
