Genius is just the threshold for me!

"Saturation production, then selecting qualified parts?"

Jiao You was initially pleased to hear that the difference wasn't that significant.

But upon hearing Lin Dong's solution, he was immediately stunned: "This is the WS-15 turbofan engine, not a machine tool or other mechanical product. Won't the cost be too high?"

"Building one engine like this would require scrapping parts from dozens or even hundreds of engines. The cost is terrifying." Xu Ziming frowned slightly.

They were all aware of this method of mass production and then selecting qualified parts from it.

Many machine tool precision upgrades are achieved using this method: mass-producing the same type of parts, then selecting the batch with the highest precision and assembling them into a machine tool with the highest precision.

After all, there are errors in processing, and these errors can be positive or negative. It's impossible for all parts to become worse; some parts will always become better.

By selecting all the better parts and assembling them into the corresponding products, the original precision limits can be broken.

This is the "selective assembly" common in the industrial field.

Many late-developing industrialized countries, facing various constraints in high-end machine tools, adopt this simplest yet most effective tactic to break through the precision bottleneck.

However, this tactic has a drawback: it requires the production of a large number of parts and products in order to select the best ones.

The parts of the WS-15 engine are not ordinary parts or products.

Other parts and products, even those with slightly lower precision, can be assembled into substandard products for sale.

This is similar to chip manufacturing; i3, i5, and i7 all use the same production diagram and process.

The i7 is a premium product with all cores intact, while the i5 is a mid-range product with one core that failed during production. So, by disabling that core, it can be turned into an i5 and still be used and sold.

As for the i3, it's a substandard product with more obsolete cores, but it can still be sold even with the downgrade disabled.

However, if the precision of the WS-15 engine is poor, the parts will be scrapped directly, and it is impossible to downgrade and assemble it.

Considering the exorbitant cost of the WS-15 itself, the total cost becomes astronomical...

"Uncle Xu, Uncle Jiao, the cost is high, but we can't just look at the production cost."

Lin Dong said earnestly, "You should view this as an industrial trial, an industrial assessment, and an industrial exam."

"Industrial trials?"

Xu Ziming and Jiao You's expressions shifted, and their eyes lit up.

Xu Ziming was particularly delighted, saying, "Could we use this WS-15 turbofan engine as a starting point to establish new industrial standards and explore a path for industrial upgrading?"

"Yes, it's not about blindly producing to capacity, but about selecting better parts."

Lin Dong said earnestly, "Instead, during the mass production process, the upstream and downstream sectors work together to establish a high-end digital twin intelligent manufacturing system. Once it matures, it can be promoted to the national industrial system..."

talking.

Lin Dong briefly explained the underlying ideas and concepts to Xu Ziming and Jiao You.

For China's industries and sectors to upgrade to high-end levels, in addition to technological innovation and R&D, the establishment and promotion of independent brands, the transformation of the industry from a processing plant to a service provider is also necessary.

In terms of specific production changes, there is only one thing: upgrading from traditional manual manufacturing to digital manufacturing, or intelligent manufacturing.

The original production model that relied on manual labor and experience has been transformed into a digital production model that relies on standardization and intelligence.

For example, in the past, processing and production required manual measurement using calipers or lasers, and then relying on experience to determine how to produce, adjust, and assemble.

If the industry is upgraded, a digital ID card can be produced by 3D scanning before each blank is processed. Then, a perfect production process can be tailored for different blanks through system algorithms, and the most suitable set of parts can be selected from hundreds or thousands of parts for assembly.

Further upgrades could combine "selection," "adjustment," and processing.

Through a high-precision online monitoring system, tool compensation is adjusted in real time to ensure that each part can closely approximate the design dimensions.

A more advanced approach involves integrating with smart cities, smart industries, and smart manufacturing, establishing dynamic adjustments and monitoring across the entire production and logistics chain. No matter where a problem occurs, the intelligent system can generate a backup plan immediately.

For example, if the situation in country A changes, it may affect the supply of raw materials. The system will detect the situation immediately, adjust the proportion of raw material procurement, and avoid unexpected events that could lead to raw material shortages and huge losses.

For example, if there is a problem with the equipment data on a certain production line and a failure is expected, the system can detect it in advance, issue a warning, allocate spare parts and arrange maintenance personnel in advance, and avoid large losses due to sudden downtime.

But regardless of which one, all of this is inseparable from a large amount of processing data, a large amount of production data, and even more so from a set of digital twin intelligent manufacturing models.

As for why Lin Dong knew these things...

Yes, the learning materials provided by the leadership already contain the analysis and planning of this industrial upgrading route.

Seeing this, he realized that digital twins combined with intelligent manufacturing is the right path for China's industrial upgrading.

As for why he was so certain that this was the correct upgrade path for China, well, let's just say... Big A loves me!

"Xiao Dong, your plan..."

Jiao You and Xu Ziming listened to Lin Dong's story and thought about it carefully for a while. After confirming that there were no logical problems, they looked at each other and were both unsure how to respond.

Good guy.

They also envisioned using this to establish a new industrial standard and explore a path for industrial upgrading.

I originally thought this idea was amazing enough.

But Lin Dong's plan was even more frightening than expected. He wanted to establish an intelligent manufacturing system with the upstream and downstream industries, and then promote it nationwide after it was successfully implemented.

"You write a detailed plan for the coking plant and ask him to mobilize the downstream factories to carry out the transformation."

Otherwise, the cost of one WS-15 engine is over 100 million yuan. Blindly using saturated production and then optimizing assembly would result in terrifyingly high costs.

"As long as there is enough profit and a specific transformation plan is provided, downstream factories will eagerly complete the transformation and upgrade on their own..."

Xu Ziming thought for a moment, then looked at Lin Dong seriously and said, "In addition, you should also write a report on this idea and plan for your godfather, and have him report it to the higher-ups. If this matter can really be accomplished, it cannot be separated from the promotion of the top level."

If your concept and plan succeed in the WS-15 engine project, then there will be no obstacles for the entire national industrial system, which will reduce the exploration and trial costs by more than 60%...

"Okay, I'll put together a list tonight," Lin Dong replied calmly, understanding what Xu Ziming meant.

If aero engines are the crown jewel of modern industry, then the WS-15 turbofan engine is the most dazzling jewel among aero engines.

The industrial mass production of the WS-15 engine represents the world's most advanced, cutting-edge, and sophisticated industrial field.

If the industrial mass production of the WS-15 engine can be achieved through intelligent manufacturing, it naturally means that the upgrading of the national industrial system can follow this same path. This will undoubtedly reduce the initial financial costs of exploration and experimentation, while accelerating the progress of the entire industrial upgrading.

"The matter is resolved. If there's nothing else, go back now."

This isn't a personal lab. Although the door is locked from the inside and not many people come here usually, it's still better to be cautious...

Xu Ziming said a few words, checked the time, and shut down the WS-15 engine test. He then gestured to Lin Dong, "A batch of materials needs to be delivered today. The entire logistics department will have to work overtime to avoid the satellites in the sky. Come over for dinner later."

"Okay, Uncle Xu, Uncle Jiao, goodbye."

Lin Dong nodded, said goodbye to the two, and turned to go through the side door to Xu Ziming's assembly workshop.

"Teacher Xiao Dong is truly a prodigy!"

Watching Lin Dong's departing figure, Jiao You couldn't help but sigh, "What a pity, I only had a boy..."

"Jiao Gong..."

Hearing this exclamation, Xu Ziming's expression twitched and he couldn't help but say, "Your husband is already a PhD, so even if you have a daughter, it won't work."

"No, that's not it. Although he's a PhD, he skipped a grade and is only twenty-three this year. He's a few months younger than Wang Rui, and less than a decade older than Professor Xiao Dong..."

"..."

Xu Ziming opened his mouth as if to say something, but after widening his eyes, he ultimately remained silent.

Sigrún has taught at the Iceland University of the Arts as a part-time lecturer since and was Dean of the Department of Fine Art from -. In – she held a research position at Reykjavík Art Museum focusing on the role of women in Icelandic art. She studied fine art at the Icelandic College of Arts and Crafts and at Pratt Institute, New York, and holds BA and MA degrees in art history and philosophy from the University of Iceland. Sigrún lives and works in Iceland.

Before the Da Hong project officially started, Lin Dong returned to the laboratory from Xu Ziming's assembly workshop without stopping, having already finalized the handling of the Emei project.

They called Wangcai over remotely, and together with the mechanical dog, they leisurely drove back to their residential compound as the sun set.

Since the Security Department began equipping itself with combat robotic dogs for patrol and defense, multiple charging points have been built at the outer base.

Wangcai doesn't need Xu Qingling to take it home to charge after upgrading its program; it can find a place to charge itself for free.

"Lin Dong!"

I had just reached the entrance of the residential area and hadn't even gone inside when suddenly, a girl's shout rang out from the side.

Ok?

Lin Dong turned his head and saw Xia Tianqiang and his daughter Xia Ran walking towards them. He immediately called out, "Uncle Xia, Xia Ran, where are you going?"

"My mom is working overtime today, so we're going to eat at the cafeteria."

Xia Tianqiang nodded in response, and Xia Ran explained, then looked at Wangcai next to Lin Dong and asked, "Aunt Xia works in the logistics department, so she must also be working overtime, right?"

"Uh-huh."

Lin Dong nodded and said without hiding anything, "I'm planning to go to Qingling's place for a free meal."

"Then I won't bother you any longer, goodbye." Xia Ran waved with a light laugh upon hearing this.

"goodbye."

Lin Dong nodded and beckoned Wangcai into the residential area.

"Let's go."

As Xia Tianqiang listened to the mechanical dog's motor disappear behind him, he looked at his daughter, whose smile had faded and whose expression had become calm, and reached out to pat Xia Ran's head with a smile.

"Today is Friday. The cafeteria has braised pig's trotters from Sichuan, but it's limited. If you go too late, they'll be gone."

"The pig's trotters are too fatty, I don't like them."

Xia Ran shook her head, then suddenly remembered something and asked, "Dad, do you use two different types of paper for printing and drafting when you're working?"

"Hmm, confidential paper and regular paper."

Xia Tianqiang replied, "Confidential paper is produced using a mixture of various wood pulps and a special process formula to eliminate chemical fingerprints and make its origin untraceable."

In addition, the paper surface has a special coating and nano-diffraction grating pattern, which can hinder the copying and scanning of the copier.

Only professionally decrypted copiers can be used to copy and scan paper.

More advanced special security paper, similar to a privacy screen on a mobile phone, can prevent cameras from taking pictures or viewing the information from a distance. However, this is less commonly used and is only employed for printing and storing top-secret documents.

"Is this confidential paper used frequently?" Xia Ran asked curiously.

Not very often.

Xia Tianqiang smiled and said, "The special confidential paper we use costs several yuan per sheet, which is nearly a hundred times the price of ordinary paper. It is generally used only when printing important documents or performing important calculations."

Using it for routine documents and calculations is wasteful, and using it in large quantities will only cause trouble for the auditors.

talking.

Xia Tian turned her head and asked curiously, "Ranran, why are you asking this?"

"It's nothing, I was just asking."

Xia Ran smiled again and took Xia Tianqiang's arm: "Let's walk faster, or Daddy won't have any pig's trotters left."
