When will I have a long tassel?

"The technical core of the Danrui 03 machine tool is a high-hard surface cutting algorithm independently developed by our research team and with complete intellectual property rights. Because it involves some technical secrets, I am not in a position to introduce all the algorithms in detail here. I am just reporting to everyone. Let’s talk about the core idea of ​​the algorithm..."

At the beginning of the appraisal meeting, Ouyang Kang stood at the lecture table, holding a laser pointer with a remote control in his hand, flipping through the presentation slides, and talking.

On the slides, one is a logical block diagram as dense as a spider web, and the other is a large section of mathematical formulas, with a few pictures occasionally interspersed to take 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, some clues can still be seen from these block diagrams and formulas. As Ouyang Kang said, it was inconvenient for him to disclose all the technical details, and all he talked about were ideas. The experts used their brain supplement skills to add in what he did not say, and found that his narrative was indeed logical. It's consistent. If we continue to follow this idea, we should be able to make some achievements.

"Based on the algorithm, we developed a special control chip for high-hard surface cutting, which we call 'Bingxin No. 1'."

Ouyang Kang waved his hand, and a close-up of an integrated circuit appeared on the screen. Two small Chinese characters in small seals on the package shone brightly, and it was the word "Mingxin".

"Wow!"

At the venue, the cheerleading team prepared by Ming Polytechnic University applauded with thunderous applause. Song Xiujie, Kang Zhichao and others saw that An Xiangping and Yuan Liang were clapping around them. Send a congratulatory smile.

"Mingxin No. 1 was independently developed by us, and we asked Taiwanese OEMs to help with the tape-out. Mingxin refers to the chip from our Mingxi Province. This time, the Danrui 03 machine tool that leaders and experts have been invited to identify is the correct one. It is equipped with Mingxin No. 1 chip.

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

Ouyang Kang spoke with enthusiasm, and it was inevitable that Lao Yu's old and kind smiling face would appear on the projection screen. Every wrinkle on his face seemed to have the word "wisdom" written on it, which made people have another impression of Mingxin No. 1. Added a bit more trust.

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

Before coming to Mingxi, Xiao Wenjun had already done some popular science for Tang Zifeng, saying that the difficulty of machining large-sized and high-hard curved surfaces actually lies in the cutting algorithm. Of course, this also has a premise, that is, China currently has solid reserves in super-hard cutting tools, precision screws, electric spindles, grating rulers and other components. As long as the algorithm problem can be solved, a machine tool can be made and Not difficult.

Kang Zhichao, Sun Min and others naturally understand this. Ouyang Kang's introduction just now was also very accurate. He did not talk about the bed design, tool selection and other issues of the Danrui 03 machine tool, but focused his introduction on the algorithm. Finally, he grandly launched a control chip integrating this algorithm, which is the so-called "Mingxin No. 1" ".

If the control system of the machine tool uses exactly this kind of Mingxin No. 1, and the machine tool can indeed complete the specified high-hard surface processing 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 , extending service life, reducing costs, etc. are all details. Even if Ouyang Kang's team does not have such experience, these large domestic machine tool companies can definitely do it.

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

In the laboratory, Ouyang Kang first disassembled the casing of the machine tool and showed the CNC circuit board to the experts. This time everyone finally saw the real thing of Mingxin No. 1, which was exactly the same as what Ouyang Kang had shown on the projection before. Ouyang Kang also asked his graduate student to bring a box containing more than a dozen identical chips. According to him, this was the finished product that had been taped out from Taiwan's OEM.

After seeing the chip, the next step is the cutting demonstration. Ouyang Kang did not do it himself, but called a graduate student and asked him to clamp the workpiece to be cut on the fixture, and then input a long series of instructions on the control panel, and then the machine tool began to work.

The requirements for the test were determined in advance and included several materials with different hardnesses and the processing of several different curved surfaces. The Danrui 03 machine tool lived up to expectations and completed the cutting operations one by one as required. Kang Zhichao, Sun Min and others appraised the finished products and confirmed that they met the design requirements. Of course, everyone has also discovered some problems with machine tools, but these problems are innocuous and are areas that need to be further strengthened in the future.

Here, there is another little trick that is not common to outsiders, that is, when appraising the results, the research team might as well leave some small flaws for the appraisal experts to catch. Because if no faults are found during an appraisal meeting, outsiders will inevitably suspect that the research team is deliberately letting things slip, and the experts in the research team will also feel that their own value has not been reflected.

The most perfect results appraisal meeting is when all the project requirements have been met, but some "room for improvement" has also been shown, so that both parties can have face and continue to cooperate next time.

Some young scholars believe that they are very high-level and make bold statements during the evaluation of results, saying that no one can find any flaws in them. This is very offensive. After a few beatings from experts, you won't suffer from this childish disease.

The appraisal of Ouyang Kang's project is very consistent with the "normal" appraisal routine. I don’t know whether he knew these skills naturally, or whether An Xiangping and others secretly taught him the techniques. In short, the techniques he displayed were very well-measured. They met the requirements of the subject, but were not absolutely perfect. Each expert has an opportunity to shine.

The experts feel happy when they say it. They have already defined the results in words, that is, they are very successful and have reached the domestic leading and internationally advanced level. Tang Zifeng followed everyone. He couldn't understand the technology and could only watch the excitement. Hearing everyone praising the Danrui 03 machine tool and the Mingxin No. 1 industrial control chip in unison, he began to doubt his previous judgment.

Could it be that this guy surnamed Ou really has a lot of skills, he just has excellent skills, but he is also a good person and good at dancing. In comparison, although Tang Zifeng was good at business, he was completely inferior in terms of technology. Compared with Ouyang Kang, he fell behind.

As a member of the machine tool industry, I should be happy that such a talent has appeared in the machine tool industry. Why do I still feel some disapproval in my heart? Could it be that I am really a narrow-minded person? When I see other people's abilities, I feel envious, jealous and hateful, and I have to find fault with them.

While Tang Zifeng was thinking about it, everyone was already walking out in a hurry, preparing to go back to the lecture hall to have a symbolic closed-door discussion and issue appraisal results for the subject. Tang Zifeng turned around and saw that Yu Xiaohui was lagging behind and was having a lively chat with a girl of similar age to her.

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

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

"Uncle Tang, let me introduce to you. Her name is Li Tiantian. She is my high school classmate. She is currently studying for graduate school with Professor Ouyang. Tiantian, this is Mr. Tang, the general manager of our Linhe Machine Tool Group."

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

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

"Really? 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. Since Li Tiantian is Yu Xiaohui's high school classmate, she is naturally from Linhe, so it is not surprising that she has heard of his name.

"Actually, I heard what Su Hua said." Li Tiantian gave Tang Zifeng an unexpected answer. When she mentioned Su Hua's name, she glanced at Yu Xiaohui inadvertently. From the corner of his eye, he could clearly see Yu Xiaohui's nose wrinkled again, which was the little girl's habitual action when she expressed her unhappiness.

Everyone had 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 parties said goodbye to each other without a few words. When Li Tiantian left, she held hands with Yu Xiaohui and said some affectionate words to each other, but Tang Zifeng felt a plastic smell filled the air.

"Why, why are you not happy when you meet an old friend in a foreign country?"

After bidding farewell to Li Tiantian, Tang Zifeng said to Yu Xiaohui knowingly.

"No, why am I unhappy?" Yu Xiaohui pretended to be innocent, but when she saw Tang Zifeng's teasing eyes, her face suddenly turned red.

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

Tang Zifeng quickly changed the subject and asked Xiaohui. After all, he is an elder. He seems old and disrespectful by teasing the younger generation about their emotional problems. It would be better to talk about technology.

Yu Xiaohui was embarrassed for a moment, then rolled her eyes at Tang Zifeng with dissatisfaction, and then replied: "I don't see any problem, don't Chief Engineer Kang, Teacher Sun and Guan Gong all think Danrui 03 is good?" Well, Uncle Tang, do you think there’s anything wrong?”

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