Chapter 846

After listening to edoo's words, a few minutes ago in front of his own people, all kinds of voluble credo wriggled his lower lips, as if to say something, but after wriggling for a long time, he didn't wriggle a word. On the contrary, an old face dissatisfied with freckles became more and more unbelievable.

In fact, it's not just eduo and credo. Director Zhao, Fang Yong, Badia, and park Zhemin are among them. When they see the scene in front of them, they all open their mouths in surprise, and then they all ask in their heart, is it the aircraft design department of Tengfei group in front of them?

This is also Too It's science fiction!

Yes, the place that Zhuang Jianye took them to visit gave people just two words, science fiction.

Although the design departments of industrial enterprises usually have the blessing of industrial design software, they can not be completely separated from the paper. After all, the computer can only solve some specific parts, and many details need to be drawn by hand.

For example, for the multi angle parameters of complex surface, the commonly used 2D design software can't cover all the information, even the more advanced 3D software can't cover all the parts.

In this case, hand drawing becomes an important part of detail design.

Of course, even if there is no manual drawing on the details, it is impossible to completely rely on computer-aided design without paper, because the process department docking with the design department, the first-line workshop also needs paper drawings to determine the process and manufacturing process. After all, at present, not all manufacturing processes can realize the numerical control of machine tools, even if the numerical control is realized, the machine tools can be designed The things designed by computer software do not match with the control software of CNC machine tools, and they can not be used.

Because of this, not to mention the domestic, even if we look at the whole world, we have not completely separated from the design department of drawings.

As a result, such a common sense basis as truth in industrial design has been completely subverted in the whole connected super large space of the new factory area of Tengfei group.

No drawings, no To be more precise, there isn't even a piece of paper.

So what do the designers do here?

Pen, but not ordinary drawing pen, but a kind of electronic pen that can be touched on the 40 inch screen and form a design idea.

Fang Yong was staring at his nearest circular screen wall like workbench.

There are more than a dozen designers in T-shirts and T-shirts sitting in front of them. They are holding electronic pens in their hands and frequently clicking on the screen in front of them. With their touch, the components on the screen are sometimes concave, sometimes convex, sometimes curved and sometimes combined.

However, this did not surprise Fang Yong. After all, they also have similar design software. As early as the mid-1980s, for the development of FB-1 fighter bomber, Northwest Airlines introduced catia-v2 version of special aircraft design software from Dassault company of France.

At that time, it became an electronic computer aided design unit no less than that of Tengfei group, which was one of the important reasons why Northwest Airlines was able to surpass other domestic enterprises in efficiency in the improvement of FB-1 fighter bombers, H6 and Y8.

Therefore, Fang Yong was not surprised to see the designers of Tengfei group doing 3D image design with electronic pen around the annular screen wall. Northwest Airlines factory can do the same thing. After all, their CATIA software has been upgraded to V3 version, which is more powerful. If not, it is impossible for them to order the project of aerial refueling aircraft in the air force. Soon, they took it out The complete design of Hongyou 6 relies on the powerful modeling, analysis and data processing capabilities of the new software.

The only difference is that the designers of Tengfei group use the electronic touch pen, while the designers of Northwest Airlines use the mouse, but there is not much difference in essence.

What shocked Fang Yong was that he turned his back to his two designers. Instead of using an electronic stylus, they were wearing something similar to a glove. On their heads, they were wearing something similar to the helmet of an airplane pilot. They were pointing and communicating quickly with their gloved hands on the screen.

Then an incredible scene appeared. The parts depicted by other designers on the workstation were combined one by one with the touch of their fingers on their screen. The two people were just like in a real production workshop. They tried a variety of processes and manufacturing methods in the process of combination, and then found the most suitable scheme, and put forward suggestions for each part according to the scheme After typing back to the designer in charge of the part design, you can revise the modification scheme.

Fang Yong didn't feel anything at first, but he was just a little curious, but his face changed when he looked at them, because he found that the two people with strange helmets and gloves could not only integrate in the macro, but also view the details in multiple dimensions.

Fang Yong watched carefully and saw such a scene. After a saddle shaped part with complex curved surface was placed on the whole, there was a connecting rod at an extremely difficult angle.

However, the designer seems to have neglected to deal with the details of the connecting rod. As a result, the efficiency of the whole large part did not meet the requirements. Two people with strange helmets and gloves found that they not only beat it back and did it again, but also provided very specific process solutions, such as No. 66 and No. 42 clamps, titanium alloy materials, chemical milling, CNC machining, EDM and so on Engineering, electrochemical boring, vacuum electron beam welding, embedded No. 6 cable and No. 8 control lineThis scene made Fang Yong dumbfounded.

In a sense, he is an expert in computer-aided design in China. If not, he would not have been able to import CATIA software from France.

However, the CATIA software of Northwest Airlines only improves the efficiency in design. It can be directly converted into direct production on some CNC machine tools made in France. The rest of the tooling, process, mold and other pre production processes are indispensable. It is still the same as the industrial production mode for decades, and it can be explored little by little according to the drawings, contents and data of the design department What tooling should be used, what process should be applied, and what kind of mould and fixture should be used.

This process is sometimes more complex than design and production, which requires repeated exploration, frequent tests and careful deliberation by technicians to come up with the optimal scheme that meets the design standards and does not exceed the manufacturing capacity.

because of this, the process is rather boring and long, sometimes even because the bottleneck on the link is a few years. Other, regardless of the Northwest FB FB fighter bomber, because of the advanced design and the lag of manufacturing, they have been separated from the manufacturing process, which has been stuck in the middle link for many years. Finally, the final plan for mass production of FB-1 fighter bombers is put forward.

This is also an important reason for the long cycle of high-end industrial products such as airplanes and rockets.

Now, however, the system of Tengfei group seems to have opened up the middle link between design and manufacturing. There is no need to go to the front-line factory to do experiments, do parameters, and sit in front of the screen to point out. A series of manufacturing information will turn into the optimal solution and present the required processes one by one.

Seeing this scene, Fang Yong was shocked, and only one sentence brushed the screen in his mind: where did you buy this thing?
