Department of Precision Mechanical Engineering, Laboratory Building.

This is a small three-story building with a green brick structure. It looks full of vicissitudes in the shade of green trees. Unlike other buildings with steps in front, the front of the door here is a slope. If all the doors of the building are opened, an old Jiefang can drive in backwards.

Qin Shaoyou parked the red rooster outside the small building, raised his head, and looked at the small building. When he saw a transformer directly supplying power to the small building, he clicked his tongue even more.

Although it was the weekend, occasional rumbles could still be heard in the small building, and it was unknown what kind of experiment it was.

"Student, is Professor Wang in there?" Seeing a student come out, Xia Miaomiao immediately went up to inquire.

"Turn left, the first laboratory."

"Thank you." Xia Miaomiao said to Qin Shaoyou who was looking around behind him, "Brother Shaoyou, we are lucky, Professor Wang is inside."

The first laboratory is very large, almost half of the floor area. When you walk to the door, you can see all kinds of precision processing equipment inside. At this time, in the innermost part, there are a group of students and a The old professor with hair is circling around a machine.

The appearance of this machine is a large rectangular parallelepiped cabinet. On the front of the cabinet, there is an openable plexiglass cover.

Several students were staring at the glass cover intently.The rumbling sound came from inside.

On the table next to the machine, there were several computers. At this time, lines of characters were beating on the screen of the computers.

When Qin Shaoyou saw this scene, he knew it was inconvenient to disturb him, so he could only watch from the sidelines. Fortunately, within a minute of standing there, the roar of the machine stopped.

The plexiglass cover was opened, and a student carefully took out the workpiece inside, placed it gently on the table, and then picked up a vernier caliper.

"No, the error is 0.2 mm larger than the previous error!"

"The last time the error was too small by 0.1 mm, this time it was too large. Could it be that our NC program has been adjusted too much?"

"Try to modify the program again, I don't believe it can't meet the requirements."

These are all senior students, and they all look very smart and capable. Some of them have red eyes, and it seems that they have stayed up all night fighting here.

"It's not a problem with the program. The rigidity of the linked double pendulum milling head of this five-axis linked CNC equipment is not enough." At this moment, a voice came from behind them.

Hearing this voice, everyone looked over, and saw a young man wearing overalls from an automobile factory in S city, with a slung canvas pocket. Where did this person come from?I haven't seen it.

However, they almost all know Xia Miaomiao next to this young man. In the University of Science and Technology, there are not many girls, and even fewer beautiful girls. , and even the name of the whole school's belle was on Xia Miaomiao's head.

"Young man, do you know this is a five-axis linkage CNC equipment?" Wang Xiaobo, with gray hair, asked Qin Shaoyou.

"Well, I recognized it at a glance. If I'm not wrong, it should be a set of five-axis linkage machining center imported from West Germany five years ago. It is mainly used to manufacture various impeller parts. As for its matching The CNC system should be Blue Sky One, right?"

"How do you know?" Suddenly a student shouted.

how do i knowBecause I am a time traveler!Qin Shaoyou touched his nose, smiled without saying a word.

Five-axis linkage CNC equipment is used to process parts with complex curved surfaces. Only the most industrially developed countries can climb this mechanically processed Mount Everest, not even the Soviet Union. Therefore, the Soviet Union imported a five-axis linkage CNC milling machine a few years ago. The propellers used to make submarines have greatly reduced their silent performance, making Soviet submarines a black hole in the ocean.

After the country's door was opened, the country once spent huge sums of money and imported seven or eight sets from abroad, all of which were treated as treasures by the country.Last year, the West imposed sanctions on the country, and this product could not be imported.

Over the past ten years, more than 100 CNC machine tools have been introduced in China. After digestion and absorption, thousands of CNC machine tools have been developed. The annual output of domestic CNC machine tools has reached several thousand units. However, this advanced five-axis CNC machine tools are still a blank, cannot be imported, and can only be developed independently.

Universities must play a prominent role in the field of scientific research, and their Department of Precision Mechanical Engineering is doing their part. Therefore, they once worked with the First Machine Tool Factory to survey and copy this imported five-axis linkage CNC machine tool, and then cooperate with The Lantian No. [-] numerical control system that is being developed in China hopes to mature it.

Qin Shaoyou remembers clearly that when he was in college, his instructor told them about domestic efforts on five-axis linkage CNC machine tools. Many early prototypes failed for various reasons.As for the one at the University of Science and Technology in S City, the reason is even more embarrassing. It takes a lot of detours to figure it out on your own!

Now these senior students regard this prototype as their graduation thesis project, and spend all day in the laboratory with Wang Xiaobo, forgetting to eat and sleep, but unfortunately, accompanying them, they have always failed.

At the beginning, it was impossible to process parts with corresponding shapes. Now the shapes of the parts are roughly the same, and the accuracy is still far behind.

They don't know how many times they have modified the program. Now, this uninvited guest who suddenly appeared, actually said that it is not a program problem, but their milling head is not rigid enough?

"Young man, are you from the automobile factory? What's the matter with you here? Or are you here to give us advice?" Wang Xiaobo continued to ask.

"Well, Professor Wang, I'm taking the liberty to come here. I hope you won't take offense. I'm Qin Shaoyou, the person in charge of the new engine project of the Automobile Factory in S City. Come here..."

Before Qin Shaoyou finished speaking, a panting voice came from behind: "Uncle Wang, don't listen to this man's nonsense, how old is he, how could he be the person in charge of the project? Is he a liar?"

"Student Xia, you have to keep your eyes open, don't be fooled by him!"

Xia Miaomiao frowned.

What is Chu Ziqiang doing here?Moreover, from the tone of the other party, he seemed to be very familiar with Professor Wang, and he actually called Uncle Wang directly?

"Senior Chu, these words are not just talking casually. How do you know Brother Shaoyou is a liar?" Although at this time Xia Miaomiao was also uncertain about Qin Shaoyou's lack of rigidity, but now, she had to We must stand firmly in front of Qin Shaoyou.
