Rebirth 79, starting from making my ex-wife regret

"I'm at home, but... our Lao Liang is a person who can't sit still. Even though he has retired due to illness, he still wants to make a difference."

As she spoke, Mrs. Liang looked towards the second floor.

At this moment, Liang Fendou was teaching a group of children upstairs.

Fang Lin interrupted and said, "Auntie, after Engineer Liang retired, did he become an after-school tutor?"

Mrs. Liang didn't know whether to laugh or cry. "According to him, his old arms and legs can't do anything else, but he can teach the children in the interest group."

"Director Wu, young comrade, please come in first. I'll go upstairs and call Lao Liang."

After a while, a group of children came out of Liang Fendou's study.

Liang Fendou said goodbye to his lover very politely.

"Old Wu, you are a rare visitor. You haven't been to my house since I retired."

After a while, Liang Fendou, who was over 50 years old, walked down the stairs to the living room on the first floor.

Wu Shengli said, "I can tell you're criticizing me for not caring about retired comrades, Engineer Liang. I've always wanted to come and see you, but I'm too busy with work."

"You also know that our country's economic restructuring has reached the critical stage, and the radio factory is the leading enterprise in the industry, so..."

"Okay, okay, I'm not blaming you. I was just asking casually. You don't have to explain so much to me. Who is this young comrade?"

Liang Fendou sat on the sofa and took the teacup handed to him by his lover.

Fang Lin stood up and said politely: "Hello, Engineer Liang, my name is Fang Lin, and I am..."

"You are Fang Lin!"

Liang Fendou was about to drink tea when he suddenly heard Fang Li's name and immediately looked at him strangely.

A person's name, the shadow of a tree.

Fang Lin has been involved in a lot of things during this period, some of which are related to the radio factory.

Liang Fendou had heard something about it.

It brought a large order to the radio factory and transformed itself from a semiconductor company into a home appliance manufacturer.

to this end.

Many people accused Fang Lin and Wu Shengli of fooling around behind their backs.

Fang Lin's attitude remained polite.

Compared with Liang Fendou, my ability is nothing.

Liang Fendou was the developer of the first CNC machine tool in Xiaguo.

Fang Lin admires Liang Fendou very much, and with the help of Wu Shengli, he came to visit the old expert today.

After some pleasantries, Wu Shengli hinted at the purpose of his visit.

Fang Lin plans to unite a large number of retired technical experts and senior technicians, make use of existing conditions, and try to research domestic four-axis CNC machine tools.

At the same time, Wu Shengli said that Fang Lin had started researching the principles of domestically produced four-axis CNC machine tools a year ago.

"You don't have to make it sound so profound. Four-axis CNC machine tools and five-axis CNC machine tools are not as mysterious as you think. The difficulty is not in the structural principles of the machine tools."

Unlike the shock expressed by several factory directors and secretaries, Liang Fendou showed no emotion when he heard that Fang Lin planned to independently develop domestic CNC machine tools.

As if he didn't care at all.

Wu Shengli wondered, "Engineer Liang, if the difficulty of researching high-end CNC machine tools is not the structural principle, then what is it?"

“Software program.”

Liang Fendou blew away the tea leaves on the gray teacup and said slowly: "Perhaps in your opinion, the greatest difficulty in researching four-axis machine tools and five-axis machines lies in understanding their technical core and internal structure. In simple terms, it is to figure out how these things are made."

"Little do people know that the core of CNC machine tools lies in the word CNC."

"Putting numerical control in front, these two words should give the answer."

Liang Fendou took a few sips of tea, put down the cup and said, "The CNC in CNC machine tools refers to the digital control system."

“The difficulty of machine tool manufacturing does not lie in understanding the principles, but in whether we can research and develop digital control programs that meet standards.”

"The software program of the machine tool directly affects several core components of the CNC machine tool, including the processing program, CNC device, servo drive device, main structure of the machine tool, and various auxiliary devices."

"At the same time, CNC machine tool research involves a lot of computer theory and semiconductor technology. Old Wu, you may not understand other things I'm talking about, but you should be able to understand processors."

CNC machine tools use a large number of microprocessors. The higher the level, the higher the requirements for the microprocessor.

The automation process is programmed software controlled by a microprocessor.

The reason why Xiaguo's second-generation CNC machine tool research fell into a trough was not only because Su Xiong withdrew the experts.

The country is facing economic difficulties, especially due to the lack of talent and technical reserves in these fields.

The fields and talents involved in CNC machine tools are extremely large.

Machinery, automation computers, and semiconductors will be further divided into dozens of categories and hundreds of supporting enterprises.

Although the second-generation domestic group project was cancelled, Liang Fendou never gave up the research on new domestic CNC machine tools in the more than 20 years since he left the project.

Unfortunately, human power is limited.

All aspects of high-end CNC machine tool design cannot be solved by him alone or by one department.

Photoelectric decoding program, temperature sensor, voltage sensor.

Just the sensor category involves more than a dozen types of sensors.

Wu Shengli was completely confused. He only knew that currently researching four-axis CNC machine tools is extremely difficult.

"Comrade, your idea is good, but any idea must respect reality."

Liang Fendou let out a long sigh.

Until now, the research progress of domestic CNC machine tools can only be described as minimal.

“Perhaps in a dozen years, we can manufacture domestically produced four-axis machine tools, or even five-axis machine tools, but definitely not now.”

Liang Fendou had no expression on his face.

There was a sense of helplessness, sadness and despair in his voice.

For many years, Liang Fendou has been working in the radio factory, but his heart is in the field of CNC machine tools.

The difficulties of high-end CNC machine tools can be divided into two categories.

Programming and program operation.

The tool selection and operation data settings during the machining process all need to be accurately calculated.

There is no perfect technical procedure.

All is in vain. ?

Fang Lin said calmly, "Engineer Liang, do you have time tomorrow? If so, can I move my computer from home to your place? The computer stores my design drawings."

"After reading the design drawings, let's discuss whether the domestically produced four-axis CNC machine tools are currently feasible for research."

“Do you have a computer at home?”

Liang Fendou's calm face finally showed an unusual reaction.

What a joke.

How could a person have a computer at home?

Even in the families of high-ranking officials, you won't see foreign gadgets like computers.

"I'll be waiting for you at home tomorrow. Bring the computer here. I want to see how much you, a young man, can understand about CNC machine tool technology."

Without waiting for Fang Lin to explain where the computer came from, Liang Fendou picked up the teacup again, as if to see him off.

How computers came about has nothing to do with Liang Fendou.

Liang Fendou just wanted to know.

What kind of machine tool design can this young man who knows how to use computer graphics produce?
