Chapter 1109: Marching 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 get to the top of the European Space Agency with complicated interests, he must not really be a fool.

Almost as soon as Kandel finished speaking, his whole aura instantly became sharper. A pair of fox-like eyes narrowed slightly and swept over the former's body 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 respond directly to Kandel's suggestion, but instead brought up a topic that seemed related, but not particularly relevant.

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, it was founded by an Internet business owner named Jeff Bezos."

In 2003, the world had not yet completely recovered from the previous 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 unfamiliar.

"But I heard that that company is still only doing some research on suborbital spacecraft?"

Obviously, Dordan was not unaware of this.

Kandel, 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 facilitate hedging bets."

He shrugged:

"Of course, ESA, as a space agency, must have corresponding supervisory powers... But as long as the market can be opened, no matter what is done, it will be purely commercial. Since it is commercial, there are a hundred ways to do it. You can bypass supervision..."

Dordan quickly captured the opponent's key points.

It is not the private capital mentioned above.

It's business behavior.

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

He changed the way he talked in circles just now and directly hit the essence.

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 it in a painless way:

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

However, Dordan is not so easily fooled:

"Bernard..."

He showed a somewhat weird smile:

"I know that after you left ESA, apart from being a nominal consultant and an honorary professor, your main business has been an independent analyst..."

At first, Dordan invited Kandel here just to ask for advice.

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

Kandel's smile froze on his face after being directly pointed out.

But it only lasted a short time:

"All right……"

Having said this, if you insist on refusing to admit it, it will affect the friendship:

"I do have many customers who hope that NASA or ESA can start the commercialization process of the aerospace 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, Over time, the risk is very high..."

"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, a considerable 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 get a huge commission from it."

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

"really."

Kandel did not deny this:

"So, it's 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... I'm afraid it's not as easy as you think."

This response seems to be negative.

But it actually leaves enough room.

"So...it's not about getting it right in one step."

Kandel smiled and said:

"First of all, you can start with some simple projects, and by the way, you can also try 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.

It’s just that the workload is really staggering.

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 machining 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 development of machine tool hardware and industrial control programs.

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 moment, no one even noticed Chang Haonan coming in from outside.

Finally, he came over and asked:

"Is there any progress?"

The sudden sound coming from behind scared several of them.

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 reaching the end point directly is quite unexpected:

"All out?"

"That's right."

Wei Yongming directly put the report that had just been printed next to Chang Haonan into Chang Haonan's hand:

"Sample No. 14, a particle swarm algorithm that replaces the particle speed update formula with Gaussian sampling of the global best position and the best position of individual particles, and sample No. 22, which is a genetic algorithm optimized for dimensionality reduction. These two The results of the group test are obviously better than those of other groups, and are actually better than our initial estimates, but it is still unclear which one is better between them..."

The optimized particle swarm algorithm itself was something Chang Haonan was optimistic about in advance.

Of course, the result did not disappoint him.

As for the other one...

"No need to conclude."

Chang Haonan quickly looked at the final result:

"Get the production end and test it in practice!"

In fact, he doesn't necessarily have to compare himself with others——

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

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

And the reason why I proposed to do production testing is just in time...

"Has the hardware adaptation on Lao Yang's side been completed?"

Wei Yongming'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 the Italians…

All I can say is that everyone who understands understands.

"It's a coincidence that 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 processing prototype machine is improved on the basis of an MS45T three-axis CNC machining center.

Therefore, from the appearance point of view, there seems to be no difference 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.

"The test begins!"

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

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. A total of 168 intermediate state centroids are generated, of which 159 (94.64%) centroids are enveloped by the optimized fixed clamping area. After 18 rounds of iterations, the objective function Converged 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.

Next, the processing program was imported into the industrial control system.

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

After the safety officer finally confirmed that the equipment was correct, the protective cover was closed.

Then, everyone heard the sound of cutting fluid impacting the milling cutter and the milling cutter cutting the raw material.

The protective cover shell has a transparent window for the operator to see the working situation inside.

However, this kind of precision processing is actually not visible to the naked eye.

Fortunately, after the upgrade, MS45T can directly display the measured value of the cutting force.

Therefore, you only need to look at the screen to get a general understanding of the current operating status of the machine tool.

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

It’s just that because the cutting edge needs to be changed to calculate the compensation amount, the speed of the tool is significantly 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 the errors caused by repeated clamping.

Even, some areas that fail to meet the requirements will be compensated for twice...

In short, it is a worry-free experience.

Yang Weihua looked at the tool-moving 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 be enough to just enter a few parameters... or even not need personnel to be on site to operate?"

Chang Haonan gently touched his chin:

"It can't be achieved in a short time, and this is just a relatively simple process like cutting."

"However, this can indeed be regarded as the first step of intelligent production..."
