Chapter 540
"Mr. Scott, this way please."

In a research institute referred to by a numerical code, Song Dingxiang accompanied the American Carter delegation led by Vice President Scott, and was visiting the laboratories one by one.In Scott's view, the Chinese seem to attach great importance to their visit this time, not only opening the doors of all laboratories for them to visit casually, but in each laboratory, there are engineers in white coats waiting, ready to visit at any time. Be ready to answer their inquiries.

For the host's hospitality, Scott maintained enough politeness, just smiled everywhere he went, and occasionally asked one or two innocuous questions.But his entourage is different. They are very interested in the achievements of the Chinese, because this will determine how Carter will cooperate with China in the future.As the group walked, they observed everything with eagle-like eyes, and at the same time lowered their voices and whispered:

"Kevin, have you noticed that the Chinese seem to be researching the moldless casting process. We only started the research on this process the year before last. How could the Chinese follow up so quickly?"

"That's not what surprised me the most, Roy. Guess what I saw in the laboratory just now. They were doing electron beam processing. Although the engineer didn't want to disclose it secretly, I think they were doing There has certainly been some progress in this area.”

"This should be the laboratory that embodies the highest level of technology in China. It's hard for me to imagine that they can master higher technology than this."

"No, you don't understand the Chinese too well. They will never show you the most advanced things. They always reveal the previous generation of technology after they have better technology."

"..."

Song Dingxiang turned a deaf ear to the mutterings of the Americans around him. The things shown to the Americans were temporarily transferred from various scientific research institutions and enterprises, which is equivalent to a demonstration of the most cutting-edge machining technology in China. Its purpose is to pave the way for the final drama.Now, they have come to the door of a large laboratory, Song Dingxiang calmed down slightly, pushed open the door, and said to Scott and others in a calm tone:

"Everyone, please allow me to introduce. This is our multi-axis high-speed machining center laboratory. We know that Carter's technology in this area is the world's leading. We very much hope that we can get guidance from Carter's peers. Our two sides can carry out some in-depth cooperation in this field.”

"Multi-axis high-speed machining?" All the Americans were slightly taken aback, and the expressions on their faces became a little stiff.They know that the Chinese have been trying to obtain this technology, but the more this is the case, the more the United States will naturally strengthen the embargo against China.This kind of processing equipment can be used for the processing of key components in some cutting-edge defense products, and it can be said that it can directly form combat effectiveness.Scott and others have always believed that the Chinese are just starting out in this field at best, but from Song Dingxiang's tone, it seems that they have made some obvious progress in this area, and they are actually able to talk about inviting Carter to guide them.

Everyone walked into the laboratory suspiciously. Hu Jin, the chief engineer, greeted him and began to replace Song Dingxiang, introducing to everyone: "Please look, this is our linear motor test bench. The feed speed we are currently testing is It is 50 meters per minute, and the future goal is 70 meters per minute. Here is a high-speed tool system test. We refer to the HSK system, KM system and NC5 system, and propose our own tool system. The combined structure of the tapered disc spring can compensate the radial clearance through axial displacement..."

Perhaps because of the visit, only the engineer who introduced the situation was left in the laboratory, and the others avoided, so the visitors of Carter Company could not see the details of the experiment.However, they can see from the various devices placed on the table that the Chinese are indeed doing these things.

After asking for permission, the American named Kevin removed a milling cutter from the tool system.He looked carefully at the handle of the knife, and found that the wear on the handle was very obvious, obviously the result of countless experiments.

"Mr. Scott, I heard that you are an expert in tool-moving strategies. We are currently doing research on tool-moving strategies under high-speed cutting conditions. Are you interested in seeing the phased results of our research?" Hu Jin asked Scott asked.

Scott smirked and said, "Of course I'm interested. I think what my Chinese counterparts have made must be very interesting."

Hu Jin took out an experiment document from the bookshelf, handed it to Scott, and said, "Look, this is the result of our simulations in the past few months. I think it must be very naive compared with Carter's technology. Bar?"

"Where is there, I have always admired the wisdom of the Chinese people." Scott said politely while taking the materials.He opened the file, glanced at it roughly, and couldn't help but feel secretly startled: Isn't this the circumcision strategy of Carter Company as a secret?How come the Chinese have also mastered it?
"How about it, Mr. Scott, do you think there is any deviation in our research thinking on the knife-moving strategy?" Hu Jin asked with an attitude of humbly asking for advice.

The tool-moving strategy is a key technology in high-speed machining. How to simplify the tool's walking path, reduce turning points, and keep the path as smooth as possible is an important factor in determining cutting efficiency.There are some rules in the tool-moving strategy. For example, for high-speed cutting of large complex surfaces, if the curvature of the surface changes greatly, the tool-moving direction should be the direction of the maximum curvature radius.Conversely, if the curvature of the surface changes little, you should choose the cutting direction with the longest average length of a single tool path.

These principles are simple to say, but to be implemented in practice involves a lot of calculations and experiments. On the basis of calculations and experiments, some specific models can be extracted, which belongs to the knowledge formed by enterprises.From the information that Hu Jin gave to Scott, it can be clearly seen that the Chinese have already mastered a considerable part of the cutting strategy, especially the strategy of circumcision, which is somewhat similar to a certain core technology of the Carter Company. place.

Scott knows that to realize this circumcision strategy, it must involve the cooperation of multiple axes. The Chinese can simulate the circumcision method, which shows that they have a relatively deep grasp of the multi-axis linkage technology.This discovery shocked Scott.

"Mr. Hu, did you all develop these strategies yourself?" Scott asked very impolitely. Of course, he could have said it more tactfully, but he couldn't care less when he was in a hurry.

A bit of embarrassment clearly appeared on Hu Jin's face. He faltered and said, "Of course, I was created by us. I don't know if it's right. We still want to hear your opinions."

Hu Jin's pretentiousness was naturally designed by Lin Zhenhua, the behind-the-scenes director. Such an expression can make Americans confused. They don't know whether the Chinese have mastered these technologies themselves, or indirectly through some channels. obtained these technologies.

Yang Wenjun and Chen Ying originally obtained this set of cutting strategies from Miryang Company. The boss of Miryang Company also worked in Carter Company in the past, so they are somewhat related in technology, so Scott looks familiar , is also normal.If he asks a few more questions, he should be able to find that the Chinese only have a half-knowledge of this technology and lack sufficient experimental data to support it.Hu Jin put on this expression just to deal with Scott's questioning. I'm already embarrassed. If you keep asking, can I refuse to answer?
"It's really not easy for you to achieve this step without any external help." Scott calmed down and began to conclude, "However, your current research has relatively large directionality problems. , if you go in this direction, you may not get the results you hope for.”

"This..." Song Dingxiang seemed a little anxious, "Mr. Scott, are you sure there is a problem with our direction? If there is a problem, we must make adjustments. By the way, can you do more in China?" Stay a few days and give us some guidance?"

Hu Jin showed some doubts, and said: "Mr. Scott, the technologies in the world are not exactly the same. Maybe our thinking is different from Carter's. You can't say that we are doing something wrong, right?" ?”

This is the difference between officials and engineers. Officials are concerned about the achievement of goals, while engineers are more concerned about whether their work can be recognized.Scott felt that he had figured out the Chinese people's thinking. He smiled reservedly and said, "Maybe there is some truth to what Mr. Hu said. I think Mr. Song can continue to trust Mr. Hu. Maybe he chooses now." This direction can indeed produce some interesting things.”

"This is not a question of who to trust." Song Dingxiang pulled Scott aside and said to him in a low voice, "Mr. Scott, you know, we are not a purely scientific research institution, and we are not interested in academic issues. For us, the key is to get the equipment we need on time and according to the quality. Mr. Scott, do you really think there is a problem with the direction Hugong and the others are doing?"

"Mr. Song, this is just my family's opinion." Scott said.

"We believe in Carter very much." Song Dingxiang said, "If Mr. Scott can produce real evidence, we can ask our engineers to change the current direction. However, this may require Mr. Scott to give us some Guidance will do."

Scott waved his hand and said, "Mr. Song, if you just need some machining centers, our Carter Company can provide them to you from the perspective of cooperation. However, we cannot provide technical guidance. After all, each Every company has its own technical secrets."
