"Xiaoye, this is the result of our latest research. "www.biquge.info Standing behind Ye Feng, Xu Lao is like a student, in the field of machine tools, the absolute authority here is Ye Feng, not them, Xu Lao feels that it is very good to be able to develop such a high-precision machine on Ye Feng's ideas, at least they have found a way forward, but today's difference, this is a lithography machine."

Ye Feng carefully watched the operation of the machine, it was much better than at the beginning, the flickering of the machine, Ye Feng looked at the data above, and had a rough plan in his heart, Ye Feng presided over the main design, and the rest of the part, Ye Feng was not interested, as long as he could achieve the goal in his heart. I have to say that this group of old experts still has their level, although their thinking is somewhat limited to the previous thinking, but now it is very good.

"Very good, how is the test going now?" Ye Feng nodded.

"The yield rate has reached 75 percent, and if we think about it again, we should be able to reach a higher level." The yield rate determines the cost of the product, which Xu Lao still understands, Xu Lao paused, "But in terms of accuracy, we have achieved perfect slicing on the same order of magnitude, compared with other companies' products, we do the best on the same order of magnitude." ”

Ye Feng smiled faintly, of course he knew what he had done, it was actually a difficult thing to upgrade the existing equipment, but there was no way, they had purchased a batch of lithography machines with not very high accuracy, and now they needed to replace these models with their own, Ye Feng was a little helpless, since Tobal wanted to use such a means, he could only cooperate.

"Yes, after a period of extreme testing, we can maintain long-term operation and start production." Ye Feng nodded, this was not what he wanted, just a simple response.

It was still very difficult for Xu Lao and them to complete such a thing, it took nearly a year, and when Ye Feng handed them over to design it, it only took three months, which made Xu Lao and them feel a little embarrassed.

"The design part needs to be further improved, and it must also be easy to maintain, not just to save space." Ye Feng smiled slightly.

"Okay, I'll let Xiao Gao and them think about it and make some changes." Xu Lao nodded, "Xiao Ye, I don't understand a little, the accuracy level of our machine tools exceeds that of lithography machines, why don't we use higher precision lithography machines?" "Xu Lao doesn't understand that the level of machine tools has reached the 100nm level, and their lithography machine uses 256nm technology, in Xu Lao's opinion, at least about 64nm technology, should be higher than their machine tool processing accuracy.

"Huh." Ye Feng smiled, "You'll know why later." Ye Feng's mysterious smile made Xu Lao a little puzzled, could it be that this machine still hid some secrets? Xu Lao thought about it carefully, the machine tool has not been tested to the limit until now, proving that Ye Feng must have made a concession to the future design, a person who can find another way, must have mastered the design he needs, just waiting for the material, now the limitation of the machine tool is the material, and the lithography machine is the same, maybe as long as there is a suitable material, then the progress of the machine tool can be realized.

Xu Lao looked at Ye Feng with some understanding, he was just a student in this aspect, and this person who was not as old as his grandson was the chief designer, and now they slowly understood Ye Feng's design ideas, but it was more difficult for them to master, Ye Feng understood the philosophy developed in Taoist theory, this kind of thinking is difficult to unify, but fortunately, Xu Lao They have slowly mastered the directional things.

"This is a machine I designed, especially for very large parts." Ye Feng took out the memory in his hand, Xu Lao and they were like treasures, extra-large? How big is it? At present, what they have delivered to the military is already very large, is it still bigger than that? What kind of Ye Feng is going to do.

"Okay, we'll take the time to do some research." Xu Lao was overjoyed, or in Ye Feng's research institute, he is like a magician, constantly surpriseing you, and it is a special surprise, Xu Lao and the others are still carrying the task of national design, but obviously they have not yet graduated, all they can do now is to follow Ye Feng's footsteps step by step and slowly move forward, extra-large? Elder Xu looked at some foreigners behind him, and then at Ye Feng, "Can it be made public?" ”

"No, it's only a partial understanding now, I've broken it down, and each team is only responsible for a part of the research and development, and I need to make a high-precision finished product." Ye Feng shook his head, although he was not worried about these people stealing teachers, but some secrets were leaked out, which was also very bad for himself, he was still very relieved for Xu Lao, after all, he was an old researcher, especially with patriotic enthusiasm, they understood the importance of secrecy, needless to say, they also knew how to do it. "Mr. Xu, you can see all the drawings, and I have already assigned the rest, and you are still responsible for this work, Mr. Xu." Ye Feng looked at Xu Lao's excited face, didn't he understand that this was so exciting? It's just a blueprint.

"Okay, leave it to me, you can rest assured, I can definitely do it." Xu Lao seems to be rejuvenated, I don't know why, he feels that he is full of energy now, Ye Feng is like a thick textbook, constantly letting you find new things, so that you have no other ideas except looking up, and you can't keep up with the speed of his thinking development at all, they are busy every day in the research institute, but he feels that it is much more meaningful than what he did before, he can see the hope of national rejuvenation, and he even feels that it will not be long before Huaxia will truly stand in the forest of the world.

Ye Feng smiled and handed the memory in his hand to Xu Lao's hand, Xu Lao was like a treasure, and carefully placed it in the chest and collar pocket of his jacket, afraid of losing it. "Xiaoye, we have also designed a machine tool, which is designed on your concept, and the processing accuracy is not high, but I still have to ask you for guidance, and we will also steal a good teacher!"

Ye Feng smiled slightly, "Old Xu is polite. Ye Feng followed behind Xu Lao, he knew that Xu Lao was doing experiments, but he didn't expect that they had already designed a machine tool in such a short time, it seemed that he had underestimated the wisdom of these people. In front of him was a huge machine, Ye Feng looked at the whole machine carefully, Xu Lao took the design drawings of his assistant and handed them to Ye Feng, Ye Feng looked at the drawings and carefully compared the machine.

"There is no way, we can only zoom in on the machine first, make every detail clear, and carefully study every aspect." Xu Lao said embarrassedly, compared to Ye Feng's design, they were too far behind. Ye Feng looked at the drawings carefully, many of the designs on it were copied from his design, the size was only enlarged in proportion, in terms of design, the only shining point was the optimization of some modules, but Ye Feng also saw that the biggest problem was that Xu Lao and they did not have good control software technology, and the control software was the core of their own design, Xu Lao They had mastered some of their own design concepts, but these were not enough.

"The main problem is in these two places!" Ye Feng was silent for a long time before pointing out two places in the design, one is the control part of the vector, and the other is the conversion part.

"Yes." Xu Lao was surprised by Ye Feng's talent, and found the key problem in such a short period of time, "We have done many experiments, and we have also adopted the fuzzy algorithm you said, but there is still no way to achieve our ideal value, the vector always has problems when fine-tuning, and the conversion mechanism does not correctly choose the trace data we need, and the two parts seem to be completely unable to connect." ”

Xu Lao really wanted to get Ye Feng's answer, but Ye Feng was also groaning, and after a long time, Ye Feng spoke, "There is nothing wrong with the idea, there are some problems in the vector selection, I think it is in three aspects, one is the Y-axis surface, the other is the T-axis surface, I think it will be better to use the principle of one-two-three-five-seven, and it is better to do one-to-one correspondence in the controller program, don't choose such a big size, we will make the size bigger, not to require the accuracy to reach a certain accuracy at once, The initial design accuracy should be 300nm. ”

Xu Lao looked at Ye Feng, is he really a young man in his twenties? All at once I found their problem, maybe there was a problem with their thinking, "Yes, we plan to control the accuracy at about 256nm." ”

"I'm in a hurry." Ye Feng shook his head, "The idea is one aspect, I think it's better to change these places first, and then do some experiments!" ”

Xu Lao understood what Ye Feng meant, the long-term life of state-owned enterprises made them a little anxious for quick success and quick profit, without considering the actual situation, they are now studying, and there is a problem in itself if they go to such a high goal all of a sudden, from simple to complex is the right way, without understanding the foundation, they immediately looked up to the highest level is to help the seedlings, and Ye Feng also saw the problem.

"The idea of controller programming is correct, as long as you adjust it slowly, you can still achieve the predetermined goal." Ye Feng looked at Xu Lao, the youngest of these people was also forty years old, Ye Feng also felt embarrassed to criticize them, no matter who they were, they had self-esteem.

"I understand, we are a little too anxious, let's spend some more time doing basic research, in fact, we have good things now, now we have time to study and study, I believe that soon we will be able to solve all the mysteries in our hearts." Xu Lao smiled, he has been doing machinery for decades, he still has this bit of courage, Ye Feng, this young man is too genius, how can these people see him as a child, he is the king of this field, everyone must surrender.
