When will I have a long tassel?

"Mr. Xia, when did you decide to jointly develop automobile-specific machine tools with Linji?"

"Mr. Xia, what prompted you to abandon foreign products and instead use domestic equipment that has no application precedent?"

“Mr.

"Mr. Xia..."

At the "Domestic Changying Brand Multi-station Automotive Special Machine Tool Signing Ceremony" jointly organized by Pujiang Automobile Group and Linhe Machine Tool Group, Pujiang General Manager Xia Chongjie sitting on the rostrum became the focus of reporters' attention, and countless long guns and short guns were They were all focused on him, and the beautiful female reporters wanted to squeeze into his arms and ask him questions.

After scolding Tang Zifeng for his shamelessness, the leadership of Puqi Group finally decided to accept the plan proposed by Linji. The two companies jointly held a signing ceremony and announced at the ceremony that Linji's multi-station machine tool was developed through long-term cooperation between the two parties. Not only does Puqi not discriminate against domestic machine tools, on the contrary, it is an active advocate and supporter of the research and development of domestic machine tools.

The public relations departments of the two companies showed their talents and invited reporters from more than a dozen national media and dozens of local media to focus on reporting on the signing ceremony. Needless to say, the reporters invited by Puzhou Automobile Group were also instructed to focus their reports on Puzhou Automobile Group Co., Ltd. Satisfaction is the goal.

Being able to accomplish things to this extent when the opportunity arises, Xia Chongjie, Mo Jingrong and others can no longer be angry with Tang Zifeng. When Tang Zifeng came to Pujiang to participate in the signing ceremony, Xia Chongjie met him in person. After the meeting, he first pretended to reprimand Tang Zifeng for not practicing martial ethics and engaging in sneak attacks. Then he turned his anger into joy and praised Tang Zifeng for being young and talented. Because, you have a flexible mind, and the waves behind are better than the waves ahead. There is no need to elaborate on these verbal words.

The signing ceremony was held very grandly. The invited guests included technical personnel and marketing personnel from major automobile companies and major machine tool companies across the country, as well as experts from several domestic and foreign universities and research institutes. After Xia Chongjie and Tang Zifeng each signed the contract text on behalf of their company, the master of ceremonies of the meeting announced the next agenda item to everyone:

The technical department of Linji Group introduced the design ideas of Changying brand multi-station automotive special machine tools to Chinese and foreign customers, peers and experts.

"Dear experts, colleagues, and customers and friends from various automobile companies, my name is Xiao Wenjun, I work at the School of Mechanical Engineering of Tsinghua University, and I am also a distinguished engineer in the technical department of Linhe Machine Tool Group Company."

Xiao Wenjun, dressed in casual clothes, walked up to the lecture table and began to talk:

"Some time ago, there was some discussion about the Changying brand multi-station automobile-specific machine tools developed by Linji Group. Some people claimed that the design ideas of Changying machine tools were plagiarized from foreign counterparts, and they also listed a number of specious so-called evidences. , causing certain damage to the reputation of Linji Group and Changying Machine Tool.

"In order to counter this absurd accusation and clear the name of Linji Group, and also to let our customers and peers better understand the characteristics of Changying Machine Tools, my colleagues and I will use this opportunity to introduce Changying brand multi-station to you in detail. The most important part of the design ideas for automobile-specific machine tools is our original experience in using systems engineering methods for the overall design of machine tools. First of all, we invited a doctoral student from the School of Mechanical Engineering at Tsinghua University who provided the core algorithm during the overall design process of Changying machine tools. Classmate Yu Xiaohui.”

Under the illumination of a flash of light, Yu Xiaohui, wearing beige overalls of Linji Group, walked onto the stage and came to Xiao Wenjun's side. She seemed to have some stage fright, her face was red, her eyes were a little jumpy, and she did not dare to look directly at the audience.

"Xiaohui, don't be nervous, just do what you told the engineers at Canglong Research Institute." Xiao Wenjun patted Yu Xiaohui on the back and encouraged her.

"Dear experts, distinguished guests, I, I, I..."

Yu Xiaohui spoke the first two sentences fairly fluently, but started to stumble at the beginning of the third sentence. She faltered a few words and didn't know how to continue. She simply stopped memorizing the lecture notes and turned to the laptop in front of her. She moved the mouse and clicked, and a slide appeared on the big screen behind her.

Yu Xiaohui looked back at the graphics and calculations on the slide, and her mind gradually calmed down. She clicked on the laser pointer, pointed at the big screen and began to explain:

"The overall design goal of machine tools is to use the most efficient and cheapest way to produce parts with specified precision requirements. For multi-station machine tools, there are hundreds of factors that affect the machining accuracy of parts, including static factors. , also includes dynamic factors. Various factors will have complex connections with each other, which determines that when we carry out the overall design of machine tools, we cannot regard these factors as isolated factors, but must use a systematic approach to conduct overall research. .

"Based on the processing requirements of multi-station machine tools, we constructed such a factor matrix, which includes machine tool frames, cutting tools, fixtures, part assembly accuracy, thermal deformation of machine tool components...

"Look, this is the model of the milling operation module in the machine tool. SC is the coordinate system matrix of the milling cutter head, SM is the auxiliary coordinate system, and SB is the coordinate system formed by the installation inclination of the cutter head..."

Mathematical models flashed one after another on the big screen. The reporters in the audience had already looked dull after hearing this, but the eyes of experts from machine tool companies and domestic and foreign research institutions flickered, obviously from Yu Xiaohui's narration. Got a lot of inspiration.

"Great, Miss Yu. The idea you proposed to combine thermal compensation, wear compensation and assembly accuracy compensation has solved the problem that has troubled me for a long time. I believe that using the model you proposed, we can combine the machine tool's The accuracy is more than doubled, and the structure of the machine tool can be greatly simplified, thus reducing the overall cost of the machine tool!"

After Yu Xiaohui finished speaking, an expert with a tall nose stood up excitedly and shouted loudly to Yu Xiaohui on the stage.

"We have used the system engineering method before, but Miss Yu has provided us with a brand new perspective. I'm so surprised. Only now do I know that systems engineering can be used in this way!" Another foreign expert also jumped up and praised. road.

"That's great. Who said that the design ideas of Linji machine tools were plagiarized?"

"It's obvious that the machine tools are designed independently by them and have very unique design ideas."

"According to this idea, we can indeed achieve high quality and low price. It seems that we should pay attention to the machine tools that are on the way."

"..."

Everyone in the venue started talking, and the reporters came to life again. They began to interview the technical staff on site with microphones, asking them to interpret the situation introduced by Yu Xiaohui. There is no way, everyone still needs to write a manuscript when they go back. Without a more popular interpretation, the manuscript cannot be written.

"Is this thing Xiaohui created so amazing? These two foreigners just now are not the shills arranged by you, are they?"

Bao Nana, who was sitting in the back row of the venue, couldn't help but ask Tang Zifeng next to her. She felt that with Tang Zifeng's integrity, it was very possible to hire a few foreign "shills" to build momentum.

Tang Zifeng shook his head and said: "No, we did not arrange childcare. Xiaohui's method was learned from the aerospace department. As you know, the level of system engineering of the Chinese aerospace department is even higher than that of the United States and the United States. Russia is convinced.

"When Xiaohui first taught the engineers at Canglong Research Institute about systems engineering methods, he shocked everyone at once. Originally, our multi-station machine tool design was nearing completion, but Chief Engineer Qin insisted on using Xiaohui The model was made and the entire design was fully optimized.

"We were able to impress Puqi this time because our machine tools are indeed unique. In terms of overall design, even Someno is not as good as us. The price of our products is only half that of Someno, and the processing accuracy and efficiency are no less than those of Someno." For Ranye, in addition to low labor costs, another big factor is that our overall design ideas are more advanced than Someye."

"So, Qimudeng is kicking the iron when he questions you from the perspective of design thinking?" Bao Nana asked with a smile.

Tang Zifeng also smiled and said: "I guess he didn't expect it. He couldn't understand the specific technical issues. There is much more room for development in terms of design thinking, so he started from here."

"If he had listened to what Xiaohui said, he probably wouldn't have felt that there was room for design thinking. I couldn't understand a word of what Xiaohui said. There were also those formulas and so on. Matrix, senior brother, do you understand it?" Bao Nana asked.

"How do I understand?" Tang Zifeng replied angrily, "I did learn the matrix, but I didn't understand it back then, and I don't remember it now."

Bao Nana remembered something and asked: "By the way, senior brother, in order to counter Qi Muden's article, you asked Xiaohui to introduce these design ideas. Will you reveal the technical know-how? What if these know-hows are learned by others? , isn’t it a pity for you?”

Tang Zifeng said: "I asked Wenjun about this matter. She said that what Xiaohui told everyone was just some introductory knowledge, and she would not explain the most valuable core technologies. Systems engineering methods are also It’s not a secret method, it’s used by every company. What’s really great about Xiaohui is that she learned it from an old engineer from the aerospace industry, and that’s a secret that’s not passed down.”

"Hehe, Xiaohui also learned the secret of not telling it?" Bao Nana smiled, and then said: "Since there is no problem of leaking secrets, then your Tang Zifeng's Sima Zhao's heart has been discovered by me. ”

"What did you find?"

"You have invited so many people to listen to Xiaohui's technical report. Are you planning to sell multi-station machine tools to them? I saw the engineers from the car companies over there, their eyes straightened. I guess I’ll have to ask you for a quote.”

"Nonsense, why should I hold such a big press conference if not to promote products? The next ten years will be the fastest growing decade for China's automobile industry. The automotive machine tool market is simply a big gold mine. I have to hurry up and get it right. Guard the road to the gold mine, lest the foreigners and little devils take advantage."
