"The technical core of Danrui 03 machine tool is a high-hard surface cutting algorithm independently developed by our research group and with complete intellectual property rights. Because there are some technical secrets involved, I can't go into all the algorithms in detail here, but I just want to report to you the core idea of the algorithm......"

At the beginning of the appraisal meeting, Ouyang Kang stood on the lecture seat, holding a laser pointer with remote control in his hand, and talked eloquently while flipping through the presentation slides.

On the slides, there will be logical block diagrams as dense as spider webs, and then there will be large paragraphs of mathematical formulas, occasionally interspersed with a few pictures, which can be regarded as taking care of the emotions of liberal arts students like Tang Zifeng.

Kang Zhichao, Sun Min, Guan Yong, Yu Xiaohui and others are all technical experts, although they are not doing research in this direction, but they can still see some clues by looking at these block diagrams and formulas. As Ouyang Kang said, it is inconvenient for him to disclose all the technical details, what he talks about is the idea, the experts used their own brain skills, and added the content that he did not say, and found that his narration is indeed logical and self-consistent, and if he continues to do it according to this idea, he should be able to make some achievements.

"On the basis of the algorithm, we have developed a special control chip for high-hard surface cutting, which we call 'Mingxin No. 1'. ”

Ouyang Kang waved his hand, and a close-up of an integrated circuit appeared on the curtain, and the two small seal Chinese characters on the package shone brightly, which was the word "Mingxin".

"Wow!"

At the venue, the cheerleaders prepared by Ming Institute of Science and Technology applauded together, and the applause was thunderous, Song Xiujie, Kang Zhichao and others saw that An Xiangping and Yuan Liang around them were clapping, and their faces couldn't hold back, so they quickly raised their hands and clapped their hands, and sent a congratulatory smile to An Xiangping.

"Mingxin No. 1 was independently developed by us, and we asked Taiwan OEM companies to help tape out. Mingxin refers to the chip of our Mingxi Province, and the Danrui 03 machine tool that the leaders and experts are invited to identify this time is equipped with the Mingxin No. 1 chip.

"Here, I would like to tell you another tidbit. The word 'Mingxin' on our chip was written by Mr. Lao Yu, a calligraphy master of our Mingxi University of Technology. In order to write these two words for us, Mr. Lao wrote seven words in a row despite his 90 years of age, and finally selected the most proud one and let us take it and print it on the chip. ”

Ouyang Kang spoke enthusiastically, and it was inevitable that Lao Yu's old and kind smiling face would appear on the projection screen, and the word "wise" seemed to be written on every wrinkle on his face, which made people trust Mingxin No. 1 again.

Ouyang Kang's speech lasted for an hour, and then the appraisal meeting entered the next link, and the experts went to the laboratory to watch the cutting operation of the Danrui 03 machine tool.

Before coming to Mingxi, Xiao Wenjun had already done some popular science for Tang Zifeng, saying that the difficulty of processing large-size and high-hard curved surfaces actually lies in the cutting algorithm. Of course, this is also a premise, that is, the domestic current superhard tools, precision lead screws, electric spindles, grating rulers and other components have a solid reserve, as long as the algorithm problem can be solved, it is not difficult to make a machine tool.

Regarding this point, Kang Zhichao, Sun Min and others naturally understand. Ouyang Kang's introduction just now is also very in place. He did not talk about the bed design and tool selection of Danrui 03 machine tools, but focused on the algorithm of the introduction, and finally launched the control chip that integrates this algorithm, which is the so-called "Mingxin No. 1".

If the control system of the machine tool uses this kind of Mingxin No. 1, and the machine tool can indeed complete the specified high-hard surface machining operation, it means that the project has achieved the expected goal, as for the next step how to improve the reliability of the machine tool, extend the service life, reduce costs, etc., are all details. Even if Ouyang Kang's team does not have such experience, these large domestic machine tool companies are completely able to do it.

"This is the CNC circuit board we use, and the main chip is our self-developed Mingxin No. 1. ”

In the laboratory, Ouyang Kang first disassembled the shell of the machine tool and showed the CNC circuit board to the experts. This time, everyone saw the real thing of Mingxin No. 1, which was exactly the same as Ouyang Kang's previous display on the projection. Ouyang Kang also asked his graduate students to bring a box containing more than a dozen of the same chips, according to him, this is the finished product that was previously taped out from the Taidao OEM.

After looking at the chip, the next step is the cutting demonstration. Ouyang Kang didn't do it himself, but called a graduate student, asked him to jam the workpiece to be cut on the fixture, and then entered a long list of instructions on the control panel, and then the machine began to work with a clatter.

The test requirements are determined in advance and include the machining of several materials of different hardness as well as several different surfaces. Danrui 03 machine tool did not live up to expectations, and completed the cutting operations one by one according to the requirements. Kang Zhichao, Sun Min and others identified the cut finished products and confirmed that they met the design requirements. Of course, we have also found some problems with machine tools, but these problems are harmless and belong to the place that needs to be further strengthened in the future.

Here, there is another trick that is not humane to outsiders, that is, when the results are appraised, the research team may wish to leave some small flaws for the appraisal experts to grasp. Because if no fault is found in an appraisal meeting, outsiders will inevitably suspect that the research group intends to release water, and the experts of the research group will also feel that their value is not reflected.

The most perfect achievement appraisal meeting is that the requirements of the project have been met, but it also shows some "room for improvement", so that both parties have face and can continue to cooperate next time.

Some young scholars, who pride themselves on a very high level, make bold statements during the appraisal of their achievements, saying that no one can find their own flaws, which is a very offensive thing. After being beaten violently by experts a few times, you will not be guilty of this childish disease.

The identification of Ouyang Kang's project is very in line with the "normal" identification routine. I don't know if he was born to understand these ways, or if An Xiangping and others taught him secretly, in short, the techniques he showed were very well measured, which not only met the requirements of the subject, but also was not absolutely perfect, leaving every expert with the opportunity to show his style.

When the experts said it was cool, the mood was also happy, and the results had been defined inside and outside the words, that is, it was very successful and reached the leading domestic and international advanced level. Tang Zifeng followed everyone, he couldn't understand the technology, he could only watch the excitement. Hearing everyone praise Danrui 03 machine tool and Mingxin No. 1 industrial control chip in unison, he began to doubt his previous judgment.

Could it be that this surnamed Ou really has a few brushes, and his skills are excellent, and he is so good at being a man, and he is good at dancing with long sleeves. In contrast, although he Tang Zifeng has a set of business operations, he is completely scum in terms of technology, and compared with Ouyang Kang, he is inferior.

There is such a talent in the machine tool industry, as a member of the machine tool industry, should be happy, why there are always some problems in the heart? Is it really a narrow-minded person, seeing that others have the ability, they have envy, jealousy and hatred, and they have to find other people's stubble.

When Tang Zifeng was thinking about it, everyone had already walked out in a daze, preparing to go back to the lecture hall for a symbolic closed-door discussion and issue appraisal results for the topic. Tang Zifeng turned his head to look and found that Yu Xiaohui was lagging behind, chatting hotly with a girl of her age.

"Xiaohui, what, do you know each other?"

Tang Zifeng stood still, waiting for Yu Xiaohui and the girl to follow, and then asked casually. He recognized this girl as one of the students who had just helped in the laboratory, and according to Ouyang Kang's introduction, she should be a graduate student under the name of him or other teachers in the research group.

"Uncle Tang, let me introduce you, her name is Li Tiantian, she is my high school classmate, and now she is studying in graduate school with Professor Ouyang. Tian Tian, this is Mr. Tang, the general manager of our Linhe Machine Tool Group. ”

Yu Xiaohui introduced Tang Zifeng and the girl to each other.

"Mr. Tang, hello, I have heard of your name. Li Tiantian greeted Tang Zifeng in a sweet voice.

"yes, I didn't know I was so famous. Tang Zifeng said, but he didn't think so. Linji Group is the largest enterprise in Linhe City, and since Li Tiantian is Yu Xiaohui's high school classmate, he is naturally also a native of Linhe, so it is not surprising that he has heard of his name.

"Actually, I heard from Su Hua. Li Tiantian gave Tang Zifeng an unexpected answer, when she mentioned Su Hua's name, she seemed to glance at Yu Xiaohui inadvertently, Tang Zifeng clearly saw Yu Xiaohui's nose wrinkled again through the corner of his eye, which was the habitual action of the little girl when she expressed her unhappiness.

Everyone wanted to go back to the lecture hall, and Li Tiantian and other students had to go back to the laboratory to clean up, so the two sides said goodbye to each other without chatting a few words. When Li Tiantian left, he and Yu Xiaohui held hands and said some affectionate words to each other, but Tang Zifeng felt that there was a smell of plastic in the air.

"Why, why aren't you so happy when you meet someone else?"

After saying goodbye to Li Tiantian, Tang Zifeng said to Yu Xiaohui knowingly.

"No, why am I not happy?" Yu Xiaohui pretended to be innocent, but when she saw Tang Zifeng's ridiculous eyes, her pretty face turned red.

"Xiaohui, do you see any problems in the cutting demonstration just now?"

Tang Zifeng hurriedly diverted the topic and asked Xiaohui. After all, he is an elder, and ridiculing the emotional problems of the younger generation seems to be disrespectful to the old, so it is better to talk about technology.

Yu Xiaohui was embarrassed for a moment, then glanced at Tang Zifeng dissatisfiedly, and then replied: "I don't see any problems, Chief Engineer Kang, as well as Teacher Sun and Guan Gong, don't they all think Danrui 03 is very good, Uncle Tang, do you think there is anything wrong?"

"Nothing. Tang Zifeng said, after that, he raised his head, looked at the back of Ouyang Kang, who was walking seven or eight steps in front of him, and was communicating with Kang Zhichao in a whisper, and said in a low voice: "I just don't like this person a little, and intuitively feel that there is something wrong with this person!"
