Chapter 27 (1/2)

On Monday, September 5, 1977, baozixuan will welcome his first class after settling down at MIT. It takes two years to complete three and a half years of courses. Most of the college students who communicate in other colleges and universities are not under great academic pressure.

There are only 22 students in their class, including 14 from other famous universities in the world. Some study civil engineering, some study computer and some study bioengineering. After all, when they just entered the university two years ago, they chose double degrees and should be responsible for their choice. As a result, the teacher will talk about a book in the second class, and then practice and examination.

Their first lesson is relatively simple, including the development process and future direction of machinery. This is not only a very simple course, but also a process of human production and use of machines. This class is taught by a 50 year old professor to these children. Kevin Bowman, a professor of German descent. He was born in a mechanical family. His grandfather was the chief engineer of Rhine metal in Germany. His family moved to the United States because of the war.

Kevin Bowman: ”in this class, let's talk about your views on the future development of machinery, including how we can help enterprises build factories and what kind of factories to build. As for the machines invented by human beings in ancient times, take it as a foundation. Textbooks like MIT are the lessons taught to you by history teachers. Who would like to share with you the relationship between machinery and factories in the future and the role of MIT in it? ”

At this time, one of the only two girls in the class stood up and said, ”Professor Bowman, Hello, my name is Jane Jones. I think the production efficiency of machines will be higher in the future; Higher requirements for production accuracy; Some labor will be gradually replaced by machines. ” In the 21st century, anyone who reads a little can express their views, but not many people can have such views in this era.

Another girl then stood up and said, ”I have to add that the proportion of CNC machine tools will be higher and higher. We will have fewer and fewer manual operations, and the factory will produce after the customer places an order. ”

Everyone is constantly expressing their views, and at this time, a person's speech makes baozixuan feel bright. I think we should integrate many current machines so that people in need can buy all the needed machines with less money, and the parts should be universal on a large scale to find a standard interface, So that the products produced by different factories can be exchanged and used with each other. To achieve the rapid replacement of parts, and the standard revolutions of the motor should be integrated according to the different needs of each industry to achieve the required standard revolutions, multi pole division.

At this time, Professor Bowman nodded thoughtfully and asked, ”what's your name?”

”My name is Louis Wallace,” said the boy who had just returned to the question.

Bowman: ”OK, Louis, what you said is very reasonable. I hope you will work hard in this regard.”

After everyone kept expressing their views, it was finally baozixuan's turn.

Bao Zixuan: ”Hello everyone, my name is Bao Zixuan. What I just heard from your classmates is very reasonable, but I think the improvement of machinery manufacturing is a systematic project. It needs the overall quality of our staff, precision processing ability and people's requirements for product use to balance and decide. I think we should expand machinery manufacturing into the industrial system. ”

”I'm thinking about a problem this holiday, that is, how do we divide the big industry? I preliminarily divide the industry into four times. I.e. industry 1.0, industry 2.0, industry 3.0 and industry 4.0. ”

”The so-called industry 1.0 is the steam age; Industry 2.0 is the era of electrification; Industry 3.0 is the information age; It is also the era we are experiencing, and industry 4.0 uses information technology to promote industrial change. I define it as the intelligent era. ”

”What we are experiencing now is the industry 3.0 stage, the electronic information age, that is, GF applies electronic and information technology to further greatly improve the degree of automatic control of manufacturing process. Turn the information we receive into products produced by the factory. ”

”Industry 4.0 should be the integration of the physical world and the virtual world calculated by the computer, the whole product life cycle, the digitization of the whole manufacturing process and the module integration based on communication technology, so as to form a new production mode of highly flexible, personalized and digital products and services.”

”In industry 4.0. We should pay attention to the construction of intelligent factories, the degree of artificial intelligence of intelligent production and the overall supporting facilities of intelligent logistics. At present, I am still trying to build an intelligent factory. In my computer, I can realize the factory construction of 16 uncomplicated parts, as well as all data connection and integrated production. If there are more, my computer computing ability will not meet the requirements. ”
