Chapter 440, trial production of machine tools

"Master Niu, this Xuantong blue and white porcelain is a good thing." After they went out, Jiang Yan played with a blue and white porcelain tea bowl in his hand and asked Niu Ye.

"Okay, I'll tell you the origin of this Xuantong blue and white porcelain." Niu Ye drank a glass of wine and opened the conversation, and Jiang Yan knew the origin of this Xuantong blue and white porcelain.

It turned out that in the second year of Xuantong, the Qing government ordered the Jingdezhen Imperial Kiln Factory to burn a batch of porcelain for the imperial palace, mainly white glazed porcelain, among which there were also a few blue and white porcelain. Xuantong blue and white is basically an extension of Guangxu blue and white, although the workmanship has been strengthened, but there has been no fundamental breakthrough in technology.

"Then according to what you say, this Xuantong blue and white porcelain is still a good thing." Jiang Yan asked.

"Good things, the longer they are stored, the more valuable they are." Niu Ye nodded.

What Jiang Yan didn't know was that Emperor Xuantong reigned for only three years, which lasted a very short time. Blue and white porcelain is mostly antique, and the level is also very high, and it can be traced back to Kangxi blue and white. Due to the progress of the times, porcelain production has been large-scale mechanized production at this time, so Xuantong porcelain has the characteristics of modern porcelain, so it is also a rare good thing in later generations.

The meal was drunk until the moonlit treetops, and a few people came out of the tavern and rode back to their homes.

The porcelain she bought originally wanted to take away, but Xu Huizhen saw that these people had drunk this virtue, so she didn't let them take it, and asked Cai Quanwu to follow Jiang Yan behind.

After relaxing for a while, he went home and took a hot bath in the space, Jiang Yan just lay on the bed and slept with someone, this night was sleepless, it was so refreshing.

Early the next morning, Jiang Yan still got up early to punch and sat there for breakfast after washing. After breakfast, Jiang Yan went directly to the research institute.

Jiang Yan's research institute began to get busy, and there were important things to do today.

In the experimental workshop, Jiang Yan looked at the group of expert students around him and said: "Comrades, next we have to make a CNC system, this CNC system is the core component of this machine tool, without which the CNC machine tool can not be completed," Jiang Yan's voice was so loud that it was almost roared, no way, the workshop is large, there are many people, and there is no megaphone, so it can only be like this.

"Mr. Jiang, how to make the CNC system?" One of the students raised his hand to ask.

"I've got an old teletypewriter that we can dismantle and transform into a CNC program actuator." Jiang Yan answered the question raised by the student just now.

Originally, the core of this CNC machine tool was a computer numerical control device. It cooperates with the system hardware through the system control software, reasonably organizes and manages the input, data processing, interpolation and output information of the CNC system, controls the execution components, and makes the CNC machine tool automatically processed according to the requirements of the operator.

However, now that this microcomputer has not yet been born, the computer is still huge, so it is not practical, but Jiang Yan naturally has his own way.

The first CNC machine in history was a new idea that Parsons had in the process of using IBM accounting computers. He asked an employee named Frank Sturland to use a computer to calculate 200 points along the edge of the profile, and then had the mechanic drill holes at each of the 200 sets of coordinate points, and as the holes were close enough to overlap, the profile of the pattern was roughly set and no additional machining was necessary. All the work that the machinist needs to do is to move the machining platform to the required coordinate point, drill a hole, then move to the next coordinate point, drill another hole, and then repeat the above actions until all the coordinate holes are drilled.

While the technology still relies on humans to operate the machines, Parsons envisions the next step in the automation process – a digitally commanded, motor-driven machine via a punch card.

Before how to control the control of this CNC machine tool Jiang Yan was also heartbroken, in one time Jiang Yan saw that the technicians in the research institute were helping people repair the typewriter and found that the electropathy program in the teletypewriter seemed to be able to be transformed into a command mechanism for CNC programs.

The mechanical typewriter works by manipulating the keys to convert the character selection, the movement of the typing arm and the typing hammer into the printing of the characters. Each time the key is pressed, the corresponding character is selected and printed on the paper. Mechanical typewriters are designed to be simple and reliable, but they are relatively slow to operate and require a certain amount of strength and skill.

It is mainly composed of keyboards, word rods, word wheels, printing plates, ink cartridges, springs, transmission mechanisms, etc.

There is no way, now there are no computers but this old way.

This old-fashioned mechanical typewriter is still something that Jiang Yan asked Wang Honghai to find.

However, it is not difficult for Jiang Yan to make such a typewriter, and now the situation is urgent, and he can only transform one, and he will definitely make it himself in the later stage, otherwise, after mass production, how many typewriters can be dismantled by himself!

"Go get that typewriter." Jiang Yan instructed the technician beside him

When several technicians heard this, they immediately went over to open the box, and inside was an old teletypewriter, the silver body covered in dust and wear.

"This typewriter is relatively old, but after all, it is professionally made, and it is suitable for us to transform and use."

So everyone couldn't wait to gather around and began to disassemble the typewriter.

Soon, the delicate character wheel and keystroke mechanism were revealed.

"Mr. Jiang, how do you want to transform these parts?" A student raised his hand to ask.

"We want to change the character wheel into a CNC program wheel that can be switched, each piece is engraved with program instructions, and then drive the wheel to rotate through the motor, read and execute the instructions according to the program order, and the CNC operation can be completed." Jiang Yan patiently explained.

"That's how it works!" Everyone suddenly realized.

"However, this one runner can only make one program, and if you want to replace it, you have to change the runner." Jiang Yan opened his mouth and said again.

In Jiang Yan's plan, this runner is a memory, which is specially used to store the data of CNC machine tools and control CNC machine tools.

"Okay, don't worry, you guys come closer and see me do it." Jiang Yan said with a smile, "First remove the character wheel." “

Two technicians carefully removed the character wheel from the mechanism.

Jiang Yan took the character wheel, took out a magnifying glass and a knife, and carefully revised it.

He carefully erased the original character marks one by one with the blade of his knife, and re-engraved the symbols representing various numerical control instructions.

After more than an hour of meticulous transformation, a brand new CNC program wheel was born.

"Okay, now that the program wheel is complete, we can now install it on the machine for testing." Jiang Yan raised the wheels high with both hands, and his face was filled with the joy of success.

Next, everyone focused on the typewriter, carefully installing and debugging.

"Attention, everyone, I'm going to do my first CNC program test." Jiang Yan plugged in the power supply, and then made a simple CNC command hole on a piece of paper.

He inserted the paper into the machine, and everyone waited with bated breath. Jiang Yan took a deep breath and slowly pressed the start button.

Just listen to the "click", the CNC program wheel begins to rotate slowly, and the character wheel triggers the corresponding keystroke lever accurately in order, making a regular "click" sound.

"It worked!" Jiang Yan shouted excitedly.

"Great!"

"Hooray!"

Everyone cheered too.

"With this CNC execution system, our CNC machine tools are not far from success!"

Jiang Yan nodded, with a relieved smile on his face.

The success of the first test of the CNC system gave everyone great encouragement.
