After listening to Edo'o's words, Crildo, who was talking endlessly in front of his own people just a few minutes ago, moved his lips twice, as if he wanted to say something, but after squirming for a long time, he couldn't move a word. When he came out, his old face, dissatisfied with freckles, became even more unbelievable.
In fact, not only Edo'o and Crildo, but Director Zhao, Fang Yong, Badia, Park Zhemin and others all opened their mouths in surprise when they saw the scene in front of them, and then invariably felt deep in their hearts. A question arises. Is the aircraft design department of Ascendas Group in front of me?
This is too science fiction!
Yes, the place Zhuang Jianye took them to visit gave people just one word: science fiction.
Although the design departments of ordinary industrial enterprises are already supported by industrial design software, it is impossible to completely break away from paper. After all, computers can only solve part of certain specific components, and many details still need to be drawn by hand.
For example, for the multi-angle parameters of complex surfaces, the commonly used two-dimensional design software cannot cover all the information, and even the more advanced three-dimensional software cannot cover everything in the combined parts.
In this case, hand-painting becomes an important part of the detailed design.
Of course, even if there is no manual drawing of details, it is impossible to completely rely on computer-aided design to completely break away from paper, because the process department and front-line workshops that interface with the design department still need paper drawings to determine the process and production and manufacturing processes. After all, in today's world But not all manufacturing processes are CNC machine tools. Even if CNC is realized, things designed by computer software will not be usable if they do not match the control software of CNC machine tools.
Because of this, there is no design department that is completely separated from the drawings, not to mention domestically, even in the whole world.
As a result, this common sense foundation that exists like truth in industrial design has been completely overturned in this large space that is connected throughout the new factory area of ??Ascendas Group.
There are no drawings, no to be more precise, there is not even a piece of paper.
So what do the designers here use for their designs?
Use a pen, but not an ordinary drawing pen, but an electronic pen that can be touched at will on the 40-inch screen and form design ideas one by one.
Fang Yong just stared at the workbench closest to him that looked like a circular screen wall.
There were more than a dozen designers wearing t-shirts and T-shirts sitting there, holding electronic pens in their hands and tapping frequently on the screen in front of them. As they touched, the parts on the screen sometimes dented. , sometimes convex, sometimes surface transformation, sometimes transformation combination.
But this did not surprise Fang Yong. After all, the Northwest Aviation Factory also had similar design software. As early as the mid-1980s, for the development of the fb-1 fighter bomber, the Northwest Aviation Factory introduced catia from the French Dassault Company. v2 version of dedicated aircraft design software.
It became a computer-aided design unit no less than Ascendas Group at that time. This was also one of the important reasons why Northwest Aviation Factory was able to outperform other domestic enterprises in terms of efficiency in the improvement of fb-1 fighter bomber and H-6 and Y-8. .
Therefore, Fang Yong was not surprised when he saw the designers of Ascendas Group using electronic pens to design three-dimensional images around the circular screen wall. Northwest Aviation Factory can also do the same. After all, their factory's catia software has been upgraded to version v3. , the function is more powerful, otherwise it would not be possible. Not long after the Air Force issued the aerial tanker project, they came up with a complete design plan for the H-6, relying on the powerful modeling, analysis and data processing capabilities of the new software. .
The only difference is that the designers of Ascendas Group use electronic stylus pens, while the designers of Northwest Airlines use mice, but there is not much difference in essence.
What shocked Fang Yong was that the two designers with their backs to him were not using electronic stylus pens. Instead, each of them wore something like a glove and something like an airplane pilot's helmet on his head. Gloved hands pointed at the screen while communicating quickly.
Then an incredible scene appeared. The components drawn by other designers at the workstation were combined one by one on their screens with the touch of their fingers. The two people were in the process of combining just like they were in a real production workshop. We try a variety of processes and manufacturing methods, and then find the most suitable solution, and propose modifications to each component based on the solution. We then call back to the designer responsible for the component design and revise it again.
Fang Yong didn¡¯t feel anything at first, he was just a little curious, but his expression changed as he looked at it, because he discovered that the two people wearing weird helmets and gloves could not only integrate on a macro scale, but also?Ability to view details in multiple dimensions.
Fang Yong watched carefully and saw this scene. After a saddle-shaped component with a complex curved surface was placed into the whole, there was a connecting rod at an angle that was extremely difficult to detect.
However, the designer seemed to have been negligent and did not pay attention to the details of the connecting rod. As a result, the function of the entire large component did not meet the requirements. Two people wearing strange helmets and gloves discovered that they not only sent it back to have it redone, but also gave it to them. Produced very specific process solutions, No. 66 and No. 42 fixtures, material titanium alloy, chemical milling, CNC machining, EDM, electrochemical boring, vacuum electron beam welding, embedded No. 6 cables and 8 No. control line
Fang Yong was stunned by this scene.
????????????????????????????????????? With a background in aircraft design, he is considered an expert in domestic computer-aided design. If not, he would not have introduced catia software from France against everyone else's opinion.
However, the catia software of Northwest Aviation Factory only improves efficiency in design. It can be directly converted into direct production on some French-made CNC machine tools. Most of the remaining pre-production processes such as tooling, technology, molds, etc. are indispensable. , it is still the same as the industrial production method for decades. According to the drawings, contents and data of the design department, we gradually explore what tooling should be used, what process should be used, and what kind of molds and fixtures should be used.
This process is sometimes more complicated than design and production. It requires technical personnel to repeatedly explore, frequent experiments, and careful deliberation to come up with the optimal solution that meets the design standards without exceeding the manufacturing capacity.
Because of this, this process is quite boring and long, and sometimes it even lasts for several years because of bottlenecks in the process. Regardless of other factors, the FB-1 fighter bomber of the Northwest Factory is due to its advanced design and manufacturing. The lags and mutual disconnection caused the intermediate links of tooling and process to be stuck for several years. The only option was to constantly compromise on design and manufacturing, and finally came up with the final plan for the mass production of the FB-1 fighter-bomber.
This is also an important reason why high-end industrial products such as aircraft and rockets have long life cycles.
But now, the system of Ascendas Group seems to have opened up the middle link between design and manufacturing. There is no need to go to the front-line factories to do experiments and parameters, sit in front of the screen and point, and a series of manufacturing information will be transformed into the final product. Youjie presents the required processes one by one.
Seeing this scene, Fang Yong was shocked, and only one sentence flashed across his mind: Where did you buy this thing?
