Chapter 1109 March towards intelligent production!

"Release private capital?"

Although Dordan has been acting like an ordinary bad old man who is obsessed with stalking, since he can work in the European aerospace industry with complicated interests, If you get to the top of the bureau, you won't really be a fool.

Almost as soon as Kandel finished speaking, his whole aura suddenly became sharper. A pair of fox-like eyes narrowed slightly and swept over the former several times.

However, just a few seconds later, Dordan once again restored his amiable image.

It was as if the changes at that moment had never existed.

"When you said that, I remembered... It seems that in 2000, a company of similar nature was established in the United States. It should be called Blue Origin?"

He did not He did not directly respond to Kandel's suggestion, but instead talked about a topic that seemed related, but not particularly close.

The latter was stunned when he heard this. It seemed that he did not expect that the other party would suddenly mention things in the United States, but he quickly nodded:

"Yes, a man named Jeff Bay. Founded by the Internet business owner of Soth ”

In 2003, the world had not yet completely recovered from the last round of the Internet bubble, and Bezos was not yet the world-famous richest man in the world.

For outsiders, it is normal for them to have never heard of it or find it strange.

“But I heard that that company is still doing some research on suborbital spacecraft?”

Obviously, Dordan is not unaware of this.

Kander, who realized that he had entered the opponent's rhythm, also reacted quickly:

"It's not important... Anyway, you don't expect this company to really research anything. It just needs a clean and safe medium to make it easy to place bets on both sides."

He shrugged:

“Of course, ESA, as the aerospace authority, must have corresponding supervisory powers... But as long as this market can be opened, no matter what is done, it will be purely commercial. Since it is commercial, then there is There are a hundred ways to circumvent supervision..."

Dordan quickly captured the other party's key points.

It is not the private capital mentioned earlier.

But business behavior.

“Do you want the aerospace industry to be commercialized?”

He changed his way of speaking in circles and hit the point directly.

Such a rapid change caught Kandel off guard.

"It's not that I hope...it's that you need it."

He still hopes to deal with the past in a painless way:

“As long as it is a project that ESA is deeply involved in, NASA will definitely get the news faster than you, the director... Instead of doing this, it is better to let ESA just Being a party A can at least make NASA and you confused."

However, Dordan is not so easy to fool:

"Bernard..."

He showed a weird smile:

"I know that after you left ESA, except for nominal consultants and honorary professors, your main business has been as an independent analyst..."

At first, Dordan invited Kandel over, and it was really just with a Ask for ideas.

But from the moment the latter talked about commercial aerospace, he had realized that the other party actually wanted the same thing from him.

Kander’s smile froze on his face after being directly pointed out.

But it only lasted a short time:

"Okay..."

Having said this, if you insist on not admitting it, it will affect the friendship:

"I do have many customers, I hope NASA Or ESA can start the commercialization process of the space industry, such as launching a commercial orbital transportation service... You know, after the Internet bubble, a lot of hot money has no good place to go. If it keeps idling, the risk will be very high for a long time..."

“But there will be no loss for you and the entire ESA. The ELDO faction can get rid of NASA’s control to a certain extent and obtain the multi-party cooperation they want. After commercialization, it will be quite Part of the orders will definitely be handed over to American companies, and the ESRO faction will not have any objections. They are all satisfied, and you, the director, will naturally be able to sit more securely..."

"And you, the middleman, can also start from There was a huge commission inside.”

Dordan spoke directly, interrupting the other party's painting.

“Indeed.”

Kander did not deny this:

“So, this is not a bad thing for all of us.”

In fact, the so-called commercial aerospace is very simple to put it bluntly.

That's outsourcing.

At first glance, it doesn’t sound like a good word.

However, for organizations like NASA or ESA that have become bloated and inefficient due to various reasons, outsourcing can reduce a lot of troubles.

Therefore, Dordan did not refuse immediately, but just thought about it alone for a while:

"Commercialization... may not be as easy as you think."

This response seems to be negative.

But in fact, it leaves enough room.

“So...it’s not about getting it right in one step.”

Kander smiled:

“First of all, you can start with some simple projects, and try it out by the way. The depth of Chinese people..."

Dordan still didn't nod.

But there was already some looseness in his eyes...

...

Commercial aerospace is naturally not something that a few people can promote with a few words.

Chang Haonan naturally had no way of knowing that several of his seemingly unrelated actions would even affect the pattern of the aerospace industry.

In the next nearly month, he spent almost all of his time at Torch Group, testing several typical multi-objective optimization algorithms.

With Chang Haonan's current theoretical foundation and a little help from the system, there is no difficulty in this task.

The workload is really amazing.

The multi-objective evolutionary algorithms proposed by academic circles in the past thirty years, even if only those with application value are considered, are no less than two hands.

Combined with the three improvement ideas proposed by Chang Haonan...

Even if some of them can be directly eliminated through theory, the remaining ones are by no means a small number.

Fortunately, for the entire adaptive processing technology, this set of algorithms is a relatively isolated part. It is only used to determine the clamping methods of different types of workpieces and will not affect the machine tool hardware and industrial control. Program development.

Until one night in early December.

Chang Haonan ended his short break and walked into the computer room as usual.

But this time, what appeared in front of him was not the busy scene of a group of researchers.

Instead, more than a dozen people, including Wei Yongming, sat around a computer and whispered.

For a while, no one even noticed Chang Haonan coming in from outside.

Finally, he came over and asked:

"Is there any progress?"

The sudden voice from behind scared several of them. A quickie. Wei Yongming also quickly stood up:

"Mr. Chang, the comparison results are out."

Although when he saw this posture, Chang Haonan guessed that there must be a breakthrough.

But the sudden rush to the finish line was quite unexpected:

“All came out?”

"That's right."

Wei Yongming directly stuffed a report that had just been printed next to him into Chang Haonan's hand:

"Sample No. 14, a method that uses the global best position and Gaussian sampling at the best position of individual particles replaces the particle swarm algorithm with the particle speed update formula, and sample No. 22 is a genetic algorithm optimized for dimensionality reduction. The test results of these two groups are significantly better than those of the other groups. In fact, It is also better than our initial estimate, but there is no conclusion yet on which one is better between the two..."

The optimized particle swarm algorithm itself was the object that Chang Haonan was optimistic about in advance.

Of course the result did not disappoint him.

As for the other one...

“There is no need to conclude.”

Chang Haonan quickly looked at the final result:

“Get the production end and actually test it. ! ”

Actually, he doesn’t have to compete——

With only two options left, and the performance is still comparable, the final result is definitely "I want them all."

Just let the customer decide which algorithm to use based on the actual situation.

The reason why we proposed to do production testing is just in time...

"The hardware adaptation on Lao Yang's side has also been completed?"

Wei Yong Ming's movement of sorting out the information in his hands stalled.

Although he and Chang Haonan are responsible for the industrial control system and the clamping and positioning algorithm, at the software level, as long as the theoretical foundation is solid and the ideas are streamlined, the results can be produced relatively stably.

On the contrary, it is the hardware aspect.

The machine tool is not a home computer and is far less compatible than the latter.

After the industrial control system is updated, it often takes a lot of effort to adapt.

In particular, most of the entire action system comes from Italy, so we have to connect with them in the middle.

And the efficiency of Italians...

It can only be said that they understand everything.

"It's a coincidence, the acceptance test just passed yesterday..."

Chang Haonan showed a satisfied smile.

……

Based on the principle of software adapting to hardware, production testing naturally had to be arranged in the workshop of Torch-C.B. Ferrari.

As Yang Weihua said before, the adaptive machining prototype machine is improved on the basis of an MS45T three-axis CNC machining center.

So from the appearance point of view, it seems to be no different from the same product next to it.

But after the machine tool is started, the production data that needs to be imported is much more complicated than that of the old model.

Three-axis machining centers cannot produce overly complex curved surfaces.

For example, when milling the flow channel of an impeller, the milling cutter needs to extend into the flow channel. If there is no swing head on the spindle or a turntable on the workbench, the processing cannot be completed.

Therefore, Chang Haonan just provided a typical aluminum alloy aircraft structural part as a test object.

The clamping and positioning algorithm itself is very complex and it is impossible to complete the calculation through the machine tool itself.

But MS45T allows external devices, which makes up for this shortcoming to a large extent.

"Testing begins!"

Following Chang Haonan's order, a group of technicians began preparations.

Soon, the algorithm control parameters and workpiece processing plan were input into the computer.

“The axial depth of cut is set to 6mm, and a non-uniform machining sequence is used to generate a total of 168 intermediate state centroids, of which 159 (94.64%) centroids are enveloped by the optimized fixed clamping area. After 18 After rounds of iterations, the objective function converges to 0.7789..."

"The coordinates of the three anchor points are A (394.73, -219.87), B (367.00, 0), C (292.07, -218.40)... ”

“……”

Wei Yongming had just reported the calculation results, and Yang Weihua had already completed the three-point fixation of the thin plate blank to be processed.

The next step is to import the processing program into the industrial control system.

Since the code has been written in advance, the whole process lasted less than 10 minutes.

After the safety officer finally confirmed that the equipment was in good condition, the protective cover was closed.

Immediately afterwards, everyone heard the sound of cutting fluid impacting the milling cutter, and the sound of the milling cutter cutting raw materials.

The protective cover shell has a transparent window that allows the operator to see clearly the working conditions inside.

But with this kind of precision processing, you can’t actually see it with the naked eye.

Fortunately, after being upgraded, MS45T can directly display the measurement value of cutting force.

Therefore, just by looking at the screen, you can get a general idea of ​​the current operating status of the machine tool.

In fact, the general processing process is not much different from the traditional method.

Just because the cutting edge needs to be changed to calculate the compensation amount, the speed of the tool feed is obviously slower, and the interval between each two rounds of action is also extended a lot.

But it saves the process of manual stress release.

It also reduces errors caused by repeated clamping.

Even, there will be secondary compensation for some areas that fail to meet the requirements...

In short, it is to highlight a worry-free thing.

Yang Weihua looked at the knife steps that kept popping up on the screen in front of him, and suddenly felt a little dazed:

"Mr. Chang, if all products can be processed in this way in the future, wouldn't it only require inputting a few parameters... ...It doesn’t even require personnel to be on site to operate it?”

Chang Haonan gently touched his chin:

“It can’t be done to this extent in a short time, and this is just cutting such a It’s just a relatively simple process.”

“However, this can indeed be regarded as the first step in intelligent production...”
