Siheyuan: Starting from a fitter

Chapter 355 Completion of 9-axis 5-linkage CNC machine tool
After the directions of the two types of engines were determined, Li Guocheng gave modification opinions, the first assistant revised the drawings, and the second assistant carried out verification simulations.

In order to speed up the calculation, when Xiao [-] starts the simulation, Xiao [-] will share most of its own computing power with Xiao [-].

This kind of work lasted for half a month, and Li Guocheng had to put down his current work because it was time to precision machine the large 9-axis 5-linkage CNC machine tool platform.

When leaving, Li Guocheng ordered Xiaoyi and Xiaoer to complete the simulation and material selection of the two engines.

The dedicated workshop of the 7** factory.

Li Guocheng, who was hoisted, devoted himself wholeheartedly to the work of precision machining of large platforms. Such work was boring and boring.

This time there were basically no onlookers, and the only sound left in the workshop was the rustling of scraping.

A whole month passed, and the processing of the large platform was finally completed.

The convoy delivered other parcels, and Master Yi was also following.

With Master Yi's help, assembly became fast.

Several operators in white coats watched, sometimes helping to pass tools and workpieces.

Half a month later, when the last piece of skin was assembled in place, the installation of the 9-axis 5-linkage CNC machine tool was completed.

When I powered on the car, I found some coordination problems.Adjust the control parameters and the problem will be solved soon.

After receiving the news, the factory leader and his technicians arrived at the workshop and took out a crankshaft formula with a complex curve. Li Guocheng completed the program based on experience.

After pressing the start button, the machine tool runs smoothly.

The cutter head is automatically switched, and the cutter head continuously cuts the steel surface according to the curve requirements.

"It's so smooth!"

"The curved surface is so beautiful. There is no need to test it. You can tell it meets the requirements by looking at it with the naked eye."

"For such a large workpiece, the clamp can actually lift it with ease."

. . . . . .

The crankshaft processing was completed in less than an hour, and people around looked at the surveyor excitedly.

When the technician completed the measurement and gave a positive answer, cheers and applause erupted in the workshop.

The next day, the workshop was already filled with factory leaders, military personnel, and ministry leaders.

When a fan blade blank with a diameter of 5 meters is placed into the fixture on the platform, the running part is automatically positioned, and then processing starts according to the program requirements.

Half a day later, a fan blade with a mirror effect appeared in front of everyone, and many engineers shed tears with excitement.

"In the past, it took us at least several months, or even a year, to process such parts. Moreover, it required repeated measurements and repeated processing, and the final processing accuracy was far from meeting the requirements."

"Yes, look at the mirror effect and the beautiful curves. We can finally process high-precision complex curved surfaces."

An engineer actually climbed onto the fan blades and wanted to kiss them.

People around them watched them silently, most of them had tears in their eyes, and no one laughed at these rude engineers.

A grand internal celebration meeting quietly started and ended quietly without disturbing the outside world.

After the meeting, Longhua Technology received the entire balance payment.At the same time, we received two more orders, one in downtown Rongcheng and one in the mountainous area of ​​Mianyang.

Since the radar has reached the final sprint stage, these two projects need to be postponed for half a year.

They also happened to use this time to build special machine tools and produce qualified large platform blanks.

Back in the laboratory, Li Guocheng rewarded everyone who participated in the project, including the structure group and software group.

This reward alone will cost 50W.

For the next week, Li Guocheng stayed in Building 3 opposite, where Kyoto Institute of Technology's radar team had been fully transferred.

Because Building 3 has a larger venue, more comprehensive equipment, and a more private environment.

For many parameters, Li Guocheng had to run back to his personal comprehensive laboratory and ask the waiter to help analyze and simulate.

After more than a month of parameter correction, the Z-1's airborne radar was successfully developed, and a comprehensive jamming experiment was carried out in the EMC laboratory. The multi-band pulse radar has a very strong anti-jamming capability.

In fact, what is even more outstanding is the onboard computer, which has 4 i1 CPU-specific motherboards that implement fast adaptive demodulation, fast Fourier transform, and power density spectrum analysis.

It can capture targets in a very short time, track 10 targets at the same time, and carry out precise strikes on targets.

For this algorithm, Li Guocheng conducted the architecture design, Kyoto Institute of Technology conducted the module design, and the code was completely implemented by Xiaosan.

The reason why he directly used Xiaosan was mainly because Li Guocheng now had a sense of urgency and had to increase the speed of design.

When designing software, Li Guocheng introduced the concept of software reliability design.

Make software operation more reliable, communication more stable, and tracking targets more accurate.

In the past, the communication channels they designed were often disconnected. In addition to strengthening the EMC anti-interference design on the hardware, Li Guocheng also enhanced the reliability design of the software interface. After the trial, the stability of the communication channel was ensured.

This made these academic schools a treasure, and these students later spread these design concepts to various units.

Li Guocheng did not participate in the field test because time was running out for car design and he could not break his promise to Song An.

The engine and gearbox have been designed. In order to obtain the optimal control curve, save fuel and quickly increase speed, Li Guocheng introduced an engine control microcomputer.

With an economical car body appearance, Li Guocheng combined the later BMW 5 Series and VOLVO S90 to design a new model that surpasses the current mainstream in the world.

The sports body appearance is based on the Wrangler Jeep, and the cool appearance makes him extremely satisfied.

Considering the other party's lack of production capacity and the lack of industrial workers, Li Guocheng compiled complete documentation on the raw materials, production, inspection, and installation of each component in detail.

In order to be more intuitive, a three-dimensional assembly diagram of the main modules is drawn.

And more than 1200 process files have been designed. As long as you are a junior high school student, you can produce the modules you need just by looking at the files.

For the core components, Li Guocheng called Song An and asked him to send people to the laboratory, where Master Yi would personally teach them production and assembly.

In order to help Song An create a perfect product that transcends the times, Li Guocheng spared no effort.

Song An was overjoyed when he received a call from Li Guocheng.After returning, he had been worried that Li Guocheng would let him go. After receiving the call, he finally let go of his worries.

He has been under a lot of pressure recently. The factory has been put into construction, basically using all the family's money, and most of the money was bank loans.

There has been no news for several months, and unfavorable news has been spread in the family. If the old man had not supported him, he would have called Li Guocheng to ask questions.

He insisted not to call because he wanted to leave an image of trust for Li Guocheng, and he didn't want to be underestimated by Li Guocheng.

As for the always cautious old man, why he supports this project so much has to do with his strong relationship network.

Song An put down the phone and asked Uncle Shen to help arrange technicians. He couldn't wait to rush to Kyoto.
