Director: The special effects are too expensive, so I had to make real shots

Chapter 86 An experiment of lighting a fire in the dark (the third update today, please subscribe)
Huaguo University of Science and Technology.

At the school gate.

"Senior Brother Xu!"

After seeing Xu Nuo get off the car, the slender man with glasses rushed up to meet him.

"Hello, are you Feng Hao?"

Xu Nuo smiled and greeted the young man in front of him.

His name is Feng Hao, and like Xu Nuo, he is from the Mechanical Engineering Department of Huaguo University of Science and Technology, but he is still studying for a Ph.

Of course, maybe in the future, when Professor Liu mentions his favorite student to others, he will say that the most powerful one is Xu Nuo.

"Yeah, brother, it's been hard work this way."

Feng Hao asked very politely.

"Fortunately, it's just that I have to get up early in the morning to catch a plane in the morning. I like to sleep late the most."

Xu Nuo laughed.

"Haha, I think there should be no one who doesn't like to sleep in." Feng Hao also said with a smile.

He is a few years younger than Xu Nuo, but Feng Hao has great admiration for this "legendary" senior brother.

He can not only have outstanding achievements in the field of scientific research, but also be successful in the sideline business. Feng Hao thinks that he is a mere Ph. D., so he can only look up to him.

"I've read your paper. It's very well written. The Chinese Journal of Mechanical Engineering has added another good paper. So it should be Dr. Feng, right?"

"I'm about to graduate with my doctorate."

"Have you figured out where to go?"

"not yet."

"I have a good place to recommend to you."

"Oh?"

When Feng Hao heard this, he immediately asked suspiciously: "Senior Brother Xu, do you recommend me a good job?"

"Shen Machine Factory."

"what?"

When he heard that it was Shen Jichang, Feng Hao was stunned: "Shen Jichang is not fast."

Yes, Feng Hao wanted to say that Shenjichang, a once glorious pearl, is now in jeopardy and basically powerless, why did the senior recommend himself to Shenjichang?

"Ha ha ha ha."

Xu Nuo just laughed out loud, and then walked into this alma mater that was so familiar with Feng Hao, who came to greet him.

University of Science and Technology!

Unexpectedly, Grandpa is back again.

This time, there are two younger sisters following behind Xu Nuo.

One is undoubtedly Xu Nuo's assistant Wen Ruohan, and the other is also an old acquaintance, Luo Bing from MSS.

Xu Nuo specifically asked Luo Wei to find her, not for anything else, but to make the series of things he was going to do next feel a little more secure, and speaking of which, what Xu Nuo was going to do was really important.

Once successful, it will change the machinery manufacturing pattern of the whole world to a certain extent.

"We're coming in right away."

Luo Bing said this through the headset.

Department of Mechanical Engineering, National Key Laboratory of CNC Machine Tools.

At this time, the laboratory is undergoing intensive preparations, led by Xu Nuo's mechanical department teacher, a leader in the field of mechanical engineering in China, who has just become an academician of the Academy of Sciences.

Outside the laboratory, there are several people who obviously don't look like a laboratory, because they are wearing black suits, each of them has a solemn expression, and they are obviously not easy to mess with.

Soon.

Xu Nuo and Feng Hao came to the laboratory.

Luo Bingshang came to talk to one of the men in black suits, and then the man led the people out of the laboratory temporarily.

"Teacher Liu."

After seeing the familiar Professor Liu, Xu Nuo immediately stepped forward and greeted him warmly.

"Xu Nuo, you know that when you told me about this experiment, I didn't sleep well for several nights, you boy!"

Liu Minghui came forward and grabbed Xu Nuo's hand, and said excitedly.

Xu Nuo looked at the teacher in front of him, and merged the memory in his mind that when he was his tutor, his hair was quite black and shiny, but now it looks half gray.

However, despite this, after meeting Xu Nuo, even though he was old, he still looked very energetic.

Afterwards, Liu Minghui began to introduce to Xu Nuo very seriously: "This machine tool is the machine tool with the highest precision that our laboratory can produce. In fact, in terms of precision machining, it can be compared with some high-end machine tools from Germany and small days. It’s just that the numerical control is too far behind, but the numerical control system seriously affects the precision of the machine tool.”

"Is this already the best?"

Xu Nuo asked.

"Yes."

"It won't be the best in the future." Xu Nuo murmured, and then stepped forward to look at the ZS235 CNC system already installed on the machine tool.

Xu Nuo came to this key laboratory of his alma mater this time to do his own ZS235 CNC system experiment.

If this machine tool plus its own ZS235 CNC system can achieve some threshold-level high-end precision standards for international high-end machine tool milling, then it means that Xu Nuo can make domestic existing higher-precision machine tools, and continue to Climb up until you reach the limits of the ZS235 CNC.

At that time, it will be enough to compete with the most advanced high-end machine tools in the world!

"These are the best students of our mechanical major in the University of Science and Technology. Let's see if we can witness the miracle of your ZS235 CNC system here today."

Liu Minghui is looking forward to it.

Then Liu Minghui said to everyone in the laboratory, including Feng Hao, "Everyone is going to conduct the first experiment."

Soon, everyone was busy.

Xu Nuo nodded slightly towards Wen Ruohan beside him.

Wen Ruohan put away a suitcase in his hand and opened it. Inside was a portable computer, but it obviously looked different from an ordinary laptop.

This is used by Xu Nuo to transfer a large amount of data to Guan Ju when he is out, and it is not used under normal circumstances.

Because generally Xu Nuo just communicates directly with Guan Ju at home with his mobile phone.

But this time is obviously different.

Because today's test will have a lot of data that Guan Ju needs to calculate and determine whether it is up to standard, as well as verify the accuracy of its own ZS235 CNC system.

This requires the use of Xu Nuo's large-scale supercomputer and artificial intelligence Guanju.

"Start positioning accuracy testing and analysis."

The positioning accuracy test is the linear motion positioning accuracy that can be achieved when the moving parts of the machine tool move under the control of the numerical control device, X-axis, Y-axis and Z-axis, repeat positioning accuracy, rotary positioning accuracy (A, B, C), rotary Motion repeat positioning accuracy and mechanical dynamic characteristics of each axis are guaranteed.

If the difference between the actual movement position of the moving parts such as the CNC lathe table and the command position is the positioning error, the factors causing the positioning error include the servo system, the detection system, the feed transmission and the guide rail error, etc. The positioning error will be It directly affects the dimensional accuracy of the processed parts.

As the test began, the tools of this machine tool began to process metal under the control of the CNC system.

"Record data."

The people in the laboratory began to record the control data of each numerical control system, and then immediately entered the data into Xu Nuo's computer equipment.

"Guan Ju, have you received the data?"

Xu Nuo asked Guan Ju.

"Received sir, calculation and analysis verification is in progress."

The accuracy of the parts processed by the machine tool calculated by Guan Ju is a prediction based on the data. After the test and processing of the laboratory is completed, as long as the accuracy of the parts reaches the range calculated by Guan Ju, it means The test of positioning accuracy test and analysis was successful.

Everyone was a little nervous.

Feng Hao and other people in the laboratory may not know what this test means, but Liu Minghui knows that once the test is successful, the domestic machine tool technology will catch up with the international advanced technology because of Xu Nuo's ZS235 CNC system. level.

Over the past decade or so, the domestic machine tool technology has basically fallen into high-end, mid-end fierce battle, and low-end involution. Such a situation is really too difficult for Huaguo.

Shenji Factory, a state-owned enterprise that used to occupy the forefront of the world in terms of machine tool share, is now facing the dilemma of bankruptcy. Countless Chinese people working in related fields are all sad.

Nowadays, it can be said to be the darkest moment in the field of domestic high-end machine tools!

Many times, Liu Minghui could not help sighing when he looked at the various equipment and instruments in the laboratory, which were not easily obtained from abroad.

The best, most advanced, and top-notch things will not be given to you. What you exchange with others will not be able to exchange for the top-notch technology. Without the top-notch equipment and instruments, many scientific and technological researches in China will be development is restricted.

This is why domestic research should start from the most basic basic science.

But Liu Minghui understood that this experiment would be to ignite a fire in the darkness. He didn't know whether the light would flicker and extinguish in the cold wind, or form a prairie fire.

But he hoped it would be a prairie fire!
Huaguo's machine tool field needs this prairie fire too much!

In the laboratory, along with the machining test of the machine tool is completed.

"Guan Ju, compare the data."

Everyone is anxiously awaiting the results of the data.

"Sir, the precision of the finished product of the test workpiece is in line with the calculation range."

When everyone heard the news, they couldn't restrain the joy on their faces instantly.

But it's not over.

"Prepare to repeat positioning accuracy test."

Repeated positioning accuracy refers to the degree of consistency of the results obtained after completing the specified operations multiple times under the same operation mode and conditions.

Because repeat positioning accuracy is generally an occasional error with a normal distribution, it will affect the consistency of batch processed parts and is a very important performance index in machine tool processing.

"Start resolution and pulse equivalent test."

For five-axis machining CNC machine tools, the accuracy indicators can be roughly divided into: positioning accuracy and repeat positioning accuracy, resolution and pulse equivalent, and indexing accuracy.

After all the accuracy indicators are tested, it means that Xynuo's ZS235 CNC system is successful!

Resolution testing refers to the smallest displacement gap that can be resolved.

For the measurement system, the resolution is the minimum displacement that can be measured, for the control system, the resolution is the minimum displacement increment that can be controlled, and the pulse equivalent is the five-axis machining CNC machine tool every time a pulse signal is sent by the CNC device. The amount of displacement produced by the displacement part.

"Graduation accuracy test preparation."

The indexing accuracy is the difference between the actual rotation angle and the commanded rotation angle when the indexing table is indexing. The indexing accuracy will affect the angular position of the part processing part in space, and also affect the coaxiality of the hole system processing.

The accuracy index tests of all five-axis CNC machine tools are being carried out in an orderly manner.

The large amount of data generated is all handed over to Guan Ju for calculation and verification.

Now, everyone in this key laboratory of CNC machine tools is anxiously waiting for Guan Ju's verification results.

Even Xu Nuo had a little bit of anticipation and nervousness.

The nervous thing is that if the verification result is wrong, then my own ZS235 CNC system means there are still flaws.

"Xu Nuo, are you sure?"

At Liu Minghui's age, if he can witness the rise of domestic machine tool technology, he will have no regrets in his life.

"OK."

Xu Nuo originally wanted to say "it should be possible", but now is the time to be more confident.

You can see everyone's nervousness.

Xu Nuo even subtly observed that the hands of the teacher Liu Minghui would shake from time to time. He usually tapped the edge of the table with his hands to relieve this tense state, and he was used to it.

"Sir, the verification calculation result is out."

Guan Ju's voice sounded.
