398 Come on, show!

Let's just talk about it!

We are just a gas turbine for civilian power generation, why do we have such a high temperature?

"I mean, that turbojet engine works the same way as our gas turbine."

"It's just that what they need is to launch the wake jet out and power the plane."

"What we need is the hot air from the gas turbine to push the main shaft of the gas turbine, and the blades rotate to cut the magnetic field lines to generate electricity."

"In principle, it's the same, but the operating temperature of our gas turbines doesn't need to be that high."

"The general operating temperature is between 185-937 degrees, so the materials needed for our gas turbines do not need to be as expensive as turbojet engines."

"As for the blades of the turbojet engine, a single crystal material is needed, because the strength of the material without grain boundaries will be higher."

"Because their blades have to work at temperatures of more than 1,700 degrees, and they have to withstand a speed of 15,000 revolutions per minute."

"This is equivalent to the centrifugal force of 10,000 times its own weight for each blade, so the material requirements are particularly high."

"Most of the blade materials used in those engines are various composite materials. And ours doesn't need that high strength, so let's just use titanium alloy. ”

Stephen gave his uncle and nephew a popular science, and the uncle and nephew understood a little bit at this time.

Then Stephen was seen taking out some metal blades from a box that were already half-finished.

After that, he took out a piece and put it on one of the machine's manipulators.

The robotic hand, like a human hand, had five fingers.

The difference is that this thing has two thumb-like fingers, which is important.

Because the human thumb is the most important functional finger on the hand.

However, there are two of them, which shows the original idea of the designer.

This manipulator firmly holds this blade.

Then the other hand, not in a hurry to come over to process.

Instead, Stephen came to the machine and pressed the LCD screen......

A touch panel poked out of the machine, and he began to crackle on it.

Apparently a series of machining instructions are being entered......

Soon Stephen had the processing instructions in place.

Then he left the robot's work area, and as soon as he walked away, the robot's two robotic hands immediately kicked into action.

At first, the manipulator holding the ferroalloy piece carried the workpiece to the front of the other hand.

And the hand did not rush to work, but looked up and down the workpiece.

It was only at this time that Yang Yinuan and the second uncle saw clearly that there were several camera-like things next to the arm of this manipulator.

"That's the laser rangefinder, and they're taking data measurements of the workpiece and then selecting the best tool feed route......"

Stephen watched the octopus' manipulation while explaining to his uncle and nephew.

At this time, Yang Yinuan and the second uncle were completely dumbfounded.

"This control system is an artificial intelligence system, right?"

The second uncle suddenly asked, and Stephen next to him was stunned at first, obviously not expecting the second uncle to recognize this.

Then he smiled and nodded: "That's right, he is an artificial intelligence processing system with self-learning function!" ”

The second uncle sighed: "This is really amazing!" ”

Yang Yinuan had never been in a factory, but before graduating from a third-rate university, he had found them an 'internship' job.

It's not so much an internship, it's actually just a matter of getting them to work in a factory, and he's seen some machine tools.

However, the second uncle is far from seeing those high-level, so he doesn't seem to understand machine tools and control systems.

The second uncle looked at his questioning expression and explained to him.

"Now those machine tools outside, when processing some parts, the processed workpiece, before the bench."

"They all need to be cut or polished into a uniform preform shape."

"Then the master of the operation will come out first for manual processing, and a series of data will be recorded during processing."

"Then, according to this set of data, CNC programming is carried out, and the programmed program is input into the system, so that other machine tools can complete the rest of the automatic processing."

"So now the requirements for CNC engineers are very high, and you have to be familiar with all kinds of machine control software."

"It is also necessary to program the machining process according to the workpiece of different shapes and specifications."

"And you also have to design the prefab according to the needs of the workpiece, and what shape the prefab will be machined into."

"In order to save materials, save processes, and facilitate machine tool processing, you have to take these into account."

"In the past, these tasks were done by engineers operating machine tools, but now it seems that there is no need to ......."

The second uncle sighed after speaking, and at this time, the machine tool in front of him had already begun to move.

The scanning and mapping elements on the machine have already measured the rough blank.

The machine then uses the shape of the blank and the shape and specifications of the last workpiece that Stephen has just entered into the computer.

The self-programming of the machining process has been completed......

The manipulator that clamped the rough blank of the titanium alloy sheet rotated the titanium alloy sheet to a very strange angle.

Then one of the fingers of the tool hand above becomes a high-speed rotating cutter head and starts to approach the workpiece.

Moments later, sparks flew and a shrill sound of metal cutting rang out in the factory.

The hard titanium alloy flakes were cut off like a knife cutting tofu.

Although Yang Yinuan didn't know the working principle of this machine tool, he knew that this titanium alloy was a very difficult metal to machine.

Although this titanium alloy has the advantages of light weight, corrosion resistance, high hardness and so on.

But the disadvantage of this thing is also very obvious, because once formed, it is very hard, and it is very difficult to process.

Whether you are die casting or cutting with a machine tool, it is very difficult.

Especially with machine tool processing, the requirements for the cutter head and the speed of the tool are very high.

It takes tens of thousands of rotations to cut this hard alloy.

However, once the drill head drilling rate is too fast, it will cause a series of problems in machining.

For example, if the motor continuously outputs high power and allows the cutter head to ensure high speed, then the problem of overheating of the motor will be triggered.

As soon as the motor overheats, program protection is triggered, and the action may be deformed.

This will lead to machining failures and scrapped workpieces.

In addition, in the process of machining, because the speed of the cutter head is too fast, and the high-frequency friction of the workpiece...
