The lathe rolls are rolling and the snow is splashing.

In front of the five-axis linkage CNC machining center that marks the "most" high-end of the human equipment manufacturing level, the diameter is half a meter wide, the thickness is almost 15 centimeters, and the "carbon sail" that looks stronger than the titanium alloy is hard to check with the naked eye.

The spherical surface is as smooth as a mirror, and it can completely reflect the figure of the next person.

From the perspective of the microscopic world, looking at the gradually forming carbon sail and the CNC cutter head that cuts the "carbon sail", the smile on Liu Feng's face gradually became stronger.

"1 filament, 95.2c"

“1.11，95.9c”

“1.06，95.4c”

“1.25，96.8c”

“……”

In the above set of data, the former represents the spherical tolerance, and the latter is the temperature of the cutter head when it comes into contact with the cutting surface of the material.

In fact, all this is reflected in Liu Feng's microcosm, which is that the small molecules of materials are moving in a "regular" manner, and he can clearly understand how many small molecules of different types there are, what is the effect of their respective movements, what happens between molecules, and what the dynamic properties of molecules are.

Under such meticulous observation conditions, it quickly ......

"I see, no wonder!"

The reason why the machining accuracy cannot reach the design tolerance is clearly visible, and Liu Feng finally breathed a sigh of relief when he saw this.

The machine continues to be processed.

This Cao Gong is also worthy of being the world's top master, only to see that under his operation, the cutting of the machine tool is smooth, just like a Danqing holy hand, in the painting of the horse.

Liu Feng watched with interest.

In the past, he had heard how good a master of level 9 was, even if he put it in any country, such a person was a treasure-like existence, and today, it seems that such an artist-like craft deserves such an honor.

A few minutes later, a smooth "carbon sail" was presented to everyone.

"Master Cao's craftsmanship has not diminished back then!"

"Lao Cao is still so powerful!"

"It's only a few minutes of work? It's such a big piece to complete, amazing!"

"What a master!"

The onlookers talked one after another.

However, Cao Wansheng shook his head, obviously quite dissatisfied with his results: "You guys take it for testing yourself!"

Then he glanced at Liu Feng, waved his hand, and handed the processed large piece to the staff beside him: "The products are not qualified, how can I have such a cheek to dare to call myself a master?"

Onlookers, you look at me, I look at you, and suddenly there is no sound.

Liu Feng and the others didn't say anything, just nodded.

Waiting for the final test results.

However, the processing time of the product did not take much, but the time spent on inspection, which took a lot of effort.

For nearly an hour, until everyone was waiting impatiently, the QC staff took the test report and came out after a long time.

"The results are in, no doubt about it, scrap!"

Quickly browsing through the test results, Cao Wansheng had a dark face and was about to hand the report in his hand to Liu Feng.

"I'll see!"

At this time, Master Qian, who was standing next to him, stood up.

After taking the report and carefully studying it for dozens of seconds, he picked up the "carbon sail" from the staff, compared the test results, and gently stroked the "carbon sail" with both hands, and shook his head for a long time:

"It's hopeless!"

Where the cutting part has not yet reached tolerance, with his ability as a ninth-level fitter, he can still trim it by hand, but where he cuts too much, even if his hands are comparable to magic axes, he can't do anything.

Seeing this, the people around sighed even more.

If even this person says so, then there is no doubt that this piece of material really costs money!

Two top processing masters, using Huaguo's most advanced five-axis linkage CNC machine tools, the final result is still a failure, naturally many people are unwilling, take the initiative to pick up the test results and browse.

They also see the operation steps of Master Cao, there is no problem at all, and even if it is them, it is impossible to do better, but why are the products always unqualified?

After looking at it for a long time, in the end, they could only be like Master Qian, looking forward to the product and sighing.

"Professor Liu, please take a look too. The person in charge finally got the test report from a bunch of masters, and after taking a look at the results, he handed it to Liu Feng with an unwilling face.

Nodding, picking up the report and looking at it for no more than two seconds, Liu Feng handed over the test report to Academician Chen beside him, and said directly: "I finally know what the problem is." ”

"Huh?"

Chen Xuedong's outstretched hands seemed to be stiffened, dumbfounded.

It's only been a few seconds since you saw the problem?

The people around him even cast surprised glances at Liu Feng.

Do you see it?!

Although he didn't know what Professor Liu was selling, in the face of the "ill-intentioned" eyes of a group of people, Chen Xuedong could only choose to "believe in his own people": "Ahem, that ...... Professor Liu, is the result really, really correct? Have you found the reason?"

"Of course, there is a problem with the test results, and I can't treat such conspicuous unqualified data as if I didn't see it, right?"

Faced with Academician Chen's inquiry, as well as the surprise, incomprehension, distrust and even contempt of the people around him, Liu Feng was calm and asked rhetorically,

"As for the cause of all this, don't you see it?"

Everyone: "......"

If they can see it, what is going on today?

"Hehe, then please ask Professor Liu to solve our doubts!" Cao Wansheng laughed angrily, this is the famous Professor Liu?

Airs!

If you can see this, Lao Tzu ate this thing directly!

"First of all, there is no problem with the machine tool and the personnel processing program," Liu Feng glanced at the people around him lightly, as if he was provoking.

Seeing this, Cao Wansheng had a dark face, and he didn't have much hope.

The people around him also sighed.

What the hell is this guy up to?

So many old experts haven't been able to find the problem, and you just look at it twice and find the problem?

It's a bit outrageous!

Therefore, some people doubted, some people disdained, and some people gloated, and most people couldn't help but look down on Liu Feng a little.

This guy,

Is it really Liu Feng?

It can't be an imposter from somewhere!

"Of course, there is no problem with our materials and design requirements!"

So what's the problem?

As if he could feel the mental activity of the people around him, the corners of Liu Feng's mouth curved,

"I heard that the most advanced seven-axis linkage CNC machine tool of M Chinese people, with the world's most advanced machine tool sensing technology, even if it is a cutter head or even a processed material, the live data at every moment can be clearly fed back to the computer, temperature, volume, density, tension, specific surface area, etc., dare to ask Cao Gong, is there such a thing?"

"What does this have to do with our problems......

Cao Wansheng was dismissive.

Liu Feng shook his head: "You just need to answer whether I am or no." ”

"Hmph! I don't know much about the seven-axis machining center, but I have seen their five-axis machining center, and the kind of sensing technology you mentioned has been widely used in their five-axis machining center, and it must be no less in the more advanced seven-axis machining center. ”

"Yes," Liu Feng smiled, his eyes staring directly into the eyes of this Master Cao, "So is there this kind of technology on our five-axis machining center?"

I don't know why, being stared at by Liu Feng like this, Cao Wansheng's eyes subconsciously dodged, and sighed: "Actually, a lot of materials ...... Their values can be within a stable range of changes, and we don't need to monitor them in real time......"

Liu Feng shook his head: "Is there such a technique?"

was asked and almost got angry: "Yes, yes, but it is difficult to reach the level of foreign five-axis machining centers...... Our five-axis CNC machine tool can only accurately feedback a few values, and most of the values are not so accurate and have no reference value. Why, is it not related to this thing?"

"Of course!"

Liu Feng's face had already shown an expression of victory, and he waved his hand to stop the old man's rebuttal:

"Let me ask you another old question, can our five-axis machining center achieve real-time monitoring of cutter heads and processing materials? That's right, no other data is needed, only the cutter heads and materials need to be monitored. ”

Cutter heads?

Cao Wansheng frowned.

Theoretically, if there was a problem with the cutter head, then it was possible to cause this, but they also checked and when the material was processed, there was no problem with their bits at all!

Even they changed all the suitable bits of the machining center, and the end result was the same!

"Are you suspecting something is wrong with the cutter head?"

Not only Cao Wansheng, but after hearing Liu Feng's words, several other masters who had controlled the "carbon sail" processing also frowned.

I thought this guy could have any high opinions, but in the end, he threw the blame on the knife, isn't it a joke?

Do you directly suspect that the reason for the firmness of the CNC machine tool is probably a little more tenable than this situation, the cutter head?

If it was really a problem with the knife head, they would have found out a long time ago!

Seeing Liu Feng nodding affirmatively, the masters were disappointed.

A layman is still a layman after all.

It's really hard for them to stand here for a long time and listen to this guy's analysis seriously, and the result is ......

It's boring and a waste of time!

"Alas, it's boring, it's a silver gun wax rod head!"

"I might as well stay in the chair and have a cup of tea, the smell is dead!"

"Who told you to be cheeky and come over?"

"Forget it, it's scattered, it's all scattered. ”

"What do you see, what's so beautiful about this! Have you practiced all the techniques at home?"

The masters shook their heads in disappointment one by one and loudly scolded the apprentices who came over to watch the excitement.

The sound of discussion and reprimand suddenly spread like a tide.

Seeing this, Chen Xuedong was really anxious for Liu Feng and pulled his sleeve, and the person in charge was also ready to stand up to save the scene, but he was stopped by Liu Feng.

Quietly waiting for the discussion to subside, Liu Feng said in a relaxed tone.

"You can ask any questions you have. ”

Although this was not the time to ask questions, and this demonstration of technology was not yet the time to give these people time to ask questions, he knew that if he didn't explain here, probably no one would listen to him.

Soon, a master stood up.

"Professor Liu, you haven't done our business, you may not know much about machine tools, we can understand this, but you are also a big professor, you shouldn't just shouldn't talk about it, is this the attitude of you people to do learning?"

"I dare to use my reputation for 30 years of work as a guarantee that there is no problem with our cutter head!

I almost pointed at his nose and said that he was famous!

Liu Feng rubbed his nose: "Old man, it is indeed a good thing to have rich experience, but sometimes, rich experience can blind people and become an obstacle to exploring the truth!"

Speaking of this, he shook his head and sighed: "The reason why I said it was the knife head is because I have such a certainty and can come up with enough convincing reasons, but the old gentlemen don't even give me time to give me reasons...... Alas!"

"Hmph, you mean that we old guys are bullying the small!"

The old man laughed angrily,

"Okay, okay, okay, we'll give you a chance! But then again, if you can't convince us, do you dare to admit in front of everyone that you are posturing and selling your reputation?"

Unexpectedly, the smell of gunpowder rose at the scene!

Seeing that the scene gradually ignited with "thick smoke", Mr. Huang, who had always been able to only play soy sauce, finally stood up, coughed with a headache, and said roundly.

"Friendly discussion, friendly discussion...... We are mainly solving problems today, you are all masters of the industry, there is no need for this. ”

In fact, Mr. Huang is also very embarrassed.

He also came from a technical background, and he could barely understand what they were saying.

Liu Feng meant that he identified the problem of the machine tool head, which he did not agree;

After all, if it's really a problem with the knife head, it's too obvious,

With the abilities of these national treasure-level masters, it is easy to discover,

It doesn't make sense that it will only appear when you, Professor Liu, are there?

This is not that he doubts Liu Feng's academic level, but he really has a specialization in the art industry.

This time, Liu Feng's bull is really a bit big!

Seeing the expression on Huang Qihui's face, Liu Feng could roughly guess that most of this person didn't believe in himself very much, but it was difficult to say it because of his face.

In fact, it's not just Huang Qihui, even if it's Academician Chen Xuedong, who is his own person, why is he optimistic about him?

however

The truth is destined to be in the hands of the few,

Sometimes it's Copernicus, sometimes it's Galileo,

And at this time......

"It seems that everyone doesn't trust me!

"If I lose, I'll do whatever you tell me to do, but if you lose...... Master Cao, Master Qian, and all the senior engineers present, you will give me free service for three years, how about it?"
