Chapter 1017 The Battle of Chips·Professor Dong's Guidance [seeking subscription]
"I'm afraid it won't work, we can't wait. The etching machine will be upgraded every one and a half to two years. According to Professor Dong's experience, when will we catch up with the islanders?" So, finish listening Professor Dong's speech, Guo Liansheng said mercilessly.
Through this conversation, he looked down on Professor Dong very much, thinking that Professor Dong was just a soil bun engineer trained in the polar bear country system, and there was not much in his stomach.
But Xu Zhenming didn't think so, "Lao Dong, you are an expert in mechanical integration technology. Can you prescribe a prescription for our etching machine project?"
In Xu Zhenming's view, Professor Dong's words are truly in line with the scientific laws of the development of machinery, machine tools, and large equipment industries.It is through generations of generations imitating the Iron Eagle fighters of the Polar Bear country that the Chinese people will have the later J20 Iron Eagle fighters.There has never been a shortcut to scientific research and development. Without 1, there would be no 100.
At this time, Professor Dong put down the bone china teacup in his hand and glanced at Guo Liansheng with a slight raised eyebrow.He probably felt the scent of Guo Liansheng's contempt, and said with a slightly tilted corner of his mouth: "Comrade Xiao Xu, I don't have a prescription, but I can give you some experience."
Professor Dong told Xu Zhenming that when Chinese people imitate foreign machine tools and mechanical equipment, they tend to ignore mechanical system problems.The mechanical system problem is actually a data model of a machine tool or mechanical equipment. What materials are used to make parts or subsystems must be calculated by the mechanical system.
"The mechanical system of each equipment has an error range value. When we imitate, the material error, machining accuracy error, motion coordination error and other system errors are within the range of the data model, then we will be considered as successful."
"If it is outside the error range of the data model set by others, your malfunctioning performance will appear. Our research institute often encounters this situation when imitating the Polar Bear National Railway Eagle fighter. It is not uncommon."
"For example, a turbofan engine, even if we can make other people's shape, it can't reach their output power. Hey..."
Professor Dong sighed, and did not take Guo Liansheng's contemptuous attitude to heart.
According to his logic, the key problem of Yiming Group's 130nm etching machine is the mechanical problem, and it is also the problem of mechanical materials and machining.As long as these problems are solved, the 130nm etching machine will be successful.
"Our country has no problems in computer technology, control software technology, etc. The problem is that basic materials, basic heat treatment, machine tool theory, mechanical system theory, etc. are lacking too much. But now, universities in China seem to all Some minor subjects are keen to train computer professionals."
Professor Dong waved his hand sadly, saying that he knew everything he could say, and he had already vomited all the goods in his stomach.When he said this, he still mocked himself as a bun with limited ability.
But Xu Zhenming didn't think so.The old man also brought out a meritorious team to produce the first generation of carrier-based Iron Eagle fighters and the first generation of stealth carrier-based Iron Eagle fighters for China.
This kind of cow says he can't do it, can you believe it?
"Thank you very much for Mr. Dong's guidance. We finally found a little direction." Thinking of this, Xu Zhenming folded his hands and thanked Professor Dong.
Guo Liansheng's expression was a bit unnatural at this time, red for a while and white for a while.He seems to have realized something, and he is thinking about some technical problems.
