Such speed is beyond Gu Zhengxin's imagination.

The phone quickly opened, and Yang Fan's voice came from inside, "I am Yang Fan, who do you mean?"

Gu Zhengxin hurriedly said: "Hello, Chief Secretary Yang, I am Gu Zhengxin from Hongqi Diesel Engine Heavy Industry Group. Do you have time now? Let me talk to you about some things."

On the phone, Yang Fan was very enthusiastic, "Mr. Gu, don't be so polite. Just tell me if you have anything."

Just now, Yang Fan was reviewing some design drawings.

With the full development of the 054 ship design work, it gradually entered the stage of meticulous design. Almost every day, a lot of design drawings are drawn, and some important and critical design drawings are often sent to Yang Fan's desk and reviewed by Yang Fan himself.

In the past, design drawings were basically sent every few days, but now, drawings were sent almost every day, from one to two copies, from three to five copies.

Even though he was reviewing the design drawings, he unexpectedly received a call from Gu Zhengxin from Hongqi Factory. Yang Fan knew that there was probably something more important, so he simply suspended the review of the design drawings and asked what was going on.

Gu Zhengxin briefly explained the situation on their side. If more than a dozen translation teams are translating French technical materials, some of the materials have been translated.

The preparation of process regulations is in progress, part of the material preparation process regulations have been completed, and the process regulations for blank processing are being carried out.

After introducing these situations, Gu Zhengxin smiled bitterly and said, "Chief Yang, the speed was quite satisfactory at the beginning. At present, our speed has slowed down significantly. I roughly estimated that it will take for a whole year to complete the preparation of all process regulations, at least for more than half a year."

This is unacceptable!

The total trial production time is only two years, and it takes so much time to prepare the process regulations alone, so it is still a bit of yarn. The trial production work cannot be completed within the specified time.

Suddenly, Yang Fan also began to ponder.

This is a big problem!

It takes so much time to prepare the process regulations. Once the trial production of the 054 ship's diesel engine cannot be completed on schedule, the risk is too great.

It may affect the entire 054 project!

The comprehensive design of the 054 ship can be completed in more than two years, and then the construction of the first ship will be carried out. At that time, at least four diesel engines will be required. If the Hongqi Factory cannot deliver it on schedule...

Yang Fan himself dared not think about it at all.

After pondering for a moment, Yang Fan reminded with concern: "Mr. Gu, your trial production time is only two years long. If this continues, it won't work!"

Gu Zhengxin smiled bitterly.

Very helpless!

Of course, he also knew that this would not work. He had to find a way to complete the preparation of these process regulations as soon as possible and conduct the trial production of the first diesel engine as soon as possible.

"Chief Yang, we know this, so we are all in a big way now, and the pressure on us is very huge. Our engineering and technical personnel are also aware of this. They work overtime every day, and even at 10 o'clock in the evening, our factory is brightly lit."

"But the workload is too great. Even if we seize all the time and complete the preparation of all process regulations, the ideal situation will take at least more than half a year, and maybe it will take nearly a year..."

I complained about the situation on their side, and then said in great admiration: "Chief Teacher Yang, the design task of the 054 ship is so huge, at least tens of thousands of design drawings are required. How did you do it? It can actually complete the comprehensive design in two or three years."

Yang Fan smiled proudly.

It also roughly helped Hongqi Factory think of a solution to the problem.

If you guess correctly, the preparation of the process regulations of Hongqi Factory must be purely manual, which of course will take a lot of time, especially the process drawing of each process.

In the preparation of process regulations, the process diagrams of the upper and lower processes are very similar, and generally do not change much. If there is a cad drawing, the speed will increase by several times.

The craftsmanship graphics are similar, and can be copied in Cad drawing, which is very convenient. But it is different if you are purely hand-drawn. You can only draw stroke by stroke, which will take a lot of time.

As he guessed this, Yang Fan asked: "Mr. Gu, which aspect of the preparation of your process regulations takes the most time?"

Gu Zhengxin sighed and said, "Of course, it is the drawing of the craftsmanship diagram of each process, and secondly, there is a large amount of text in each process. This requires neat imitation of Song characters, which is also very time-consuming."

It's true.

Yang Fan knew that his guess was correct.

As long as the drawing of craft graphics and the writing of imitation Song characters is solved, it will solve the big problem, and Cad can solve this problem.

So, Yang Fan reminded: "You have considered using computer-aided drawings. If you use cad to prepare process regulations, I think the efficiency can be improved several times. The work that originally took nearly a year to complete may be completed in three, four months, or even two or three months."

What!

Computer-aided drawing!

Use cad to prepare process regulations!

It can be completed in two or three months!

Suddenly, Gu Zhengxin became a little excited and asked loudly: "Is cad really effective like this? It's incredible."

As the chief engineer of Hongqi Factory and is specifically responsible for the technical work of the entire factory, he certainly has heard of computer-aided drawing.

It seems that I have been using that thing abroad for a long time. I have seen some introductions from some foreign language materials and learned a little bit, but I don’t seem to see any unit using computer-aided drawings in China.

Faced with Gu Zhengxin's questions, Yang Fan laughed and said proudly: "Mr. Gu, you probably don't know yet. Our Donghai Institute has fully used Cad drawings, which is why we are fully confident that we will complete the comprehensive design within two or three years."

What!

You have used cad drawing in full!

Gu Zhengxin was shocked again, as if he had heard a huge news. As far as he knew, it seemed that there was no unit in China who had fully used the Cad. Even if there was one, it was just a try and sporadic use.

"No way!"

Gu Zhengxin couldn't help but exclaim on the phone, and then said, "Chief Yang, you really use Cad drawings in full."

In fact, he also knew that Yang Fan should not have lie to him.

However, this incident was so shocking that he couldn't accept it for a while. After several seconds, he said in admiration: "You are so amazing that you have used Cad drawings in full."

Yang Fan suggested: "Mr. Gu, if you have time, you can come to us to take a look and examine the usage of the cad, which may be helpful to you."

Come on, be sure to come!

I definitely have to take a look!

Without hesitation, Gu Zhengxin said: "Then we will come here immediately and we will go to the East China Sea Institute tomorrow. However, this may disturb your normal work."

"Where, where." Yang Fan said: "I will send someone to the airport to pick you up. Welcome to the East China Sea Institute for a visit and inspection."

"Haha, the inspection is not considered a matter of consideration." Gu Zhengxin felt much better and seemed to see hope all of a sudden. "We came here to visit and learn humbly."

On the phone, the two chatted for a while.

The next chat will be much easier.

Gu Zhengxin's heart seemed to have flown to Donghai City long ago. He had heard of computer-aided drawing. After listening to Yang Fan's description, he wanted to see what it was like, especially how efficient the drawing was.

The next day.

In the morning, a domestic flight from the northwest region landed at Donghai International Airport, with hundreds of passengers falling from the plane, including Gu Zhengxin and several others.

Gu Zhengxin walked in the front, followed by Yuan Hui, director of the Hongqi Factory Technical Center, then the technical deputy directors of the rough workshop, assembly workshop, several major manufacturing workshops, and two young technicians who understand computer operations.

A group of eleven people is considered a huge lineup.

This also shows Gu Zhengxin's emphasis on this matter.

Gu Zhengxin waved his hand and said, "Everyone should hurry up and try to arrive at the Donghai Institute earlier and see what the other person's Cad drawing looks like."

Everyone's part has accelerated.

One of the technical deputy directors asked: "Mr. Gu, is Cad drawing really efficient? I just heard of such things abroad."

Gu Zhengxin said confidently: "You think, how much is the design task of the 054 ship? As far as I know, the designers of the Donghai Institute only have two or three hundred. They can complete the comprehensive design within two or three years, which shows how efficient the Cad drawing is."

After saying this, the others became eager again.

The group quickly walked out of the airport and immediately saw the person coming to greet him. He held a sign with the words "Welcome xxxx and other lines" on it.

Gu Zhengxin walked over first and shook hands enthusiastically with Li Jun, deputy director of the 054 Model Office who came to greet him, "Comrade, I am Gu Zhengxin, thank you for your hard work."

Li Jun said enthusiastically: "Mr. Gu, you all get in the car. Chief Yang is already waiting for you to come in the institute."

Everyone got on the bus one after another. It was a 70% or 80% new minibus. There was no problem with riding a dozen people. Soon after, the car started and headed to the East China Sea Institute.

While riding in the car, the others looked outside through the window and felt the big city of Donghai City. Gu Zhengxin was not thinking about it here. He wanted to arrive at Donghai Institute earlier and see how the designers of Donghai Institute used cad to draw design drawings.

About four or fifty minutes later, the car arrived at the Donghai Station.

Getting off the bus in front of the office building, Li Jun led everyone and his group into a reception room on the third floor, where fruits, hot tea, snacks and other things were prepared.

Not long after Gu Zhengxin and the others sat down, there was a sound of footsteps outside the door. Yang Fan walked in with a smile on his face. As soon as he entered the door, he stretched out his hand and said loudly: "Mr. Gu, welcome your arrival!"

Gu Zhengxin quickly stood up, took a few steps forward, shook hands with Yang Fan tightly.

Chapter completed!
