A nation's industrial development begins with junior engineers.

"Hey, Old Wang, a thief has broken in!"

"Stop shouting! It's right here! The original has already been sent elsewhere, this is a copy..." Secretary Liu put down what she was holding.

"I told you yesterday, how could you forget?"

Jiang Xia calmed down and thought back. He realized that when he was drawing yesterday, Secretary Liu had indeed said something to him, but he was so engrossed in his creative thinking that he hadn't paid any attention.

Okay, it's a small matter, let's ignore it.

With the blueprints in hand, Teacher Yuanjiu and Xiaodaimao began discussing them.

Gradually, Jiang Xia finally understood the important reason why Teacher Yuanjiu had sought him out.

"Large precision centrifuges? Aren't the current centrifuges large enough for your needs?"

"Not enough! What I need is a testing platform that can verify single-degree-of-freedom liquid-floating gyroscopes!"

"Oh, so it all boils down to a gyroscope. But, Mr. Hara, didn't you know we're playing with lasers?"

Jiang Xia raised his head, looking at him with an expression that said, "Come and praise me!"

Mr. Yuanjiu chuckled, "I know, of course I know. I also contributed a little to it. But, the precision centrifuge I'm talking about is also intended to be used to simulate the mechanical environment of spacecraft..."

"Moreover, a single laser gyroscope isn't enough to satisfy my appetite." As he spoke, Teacher Yuan Jiu moved closer to Jiang Xia and lowered his voice.

"Some things require the use of a liquid-floating pendulum accelerometer in conjunction..."

Well, dude, even with so much inertial guidance technology, it can probably only float in the sky and spin around, while simultaneously playing that "Dongfanghong" thing.

Are you starting this early?

Just as Xiao Dai Mao was letting his thoughts wander, Teacher Yuan Jiu wrote down some data and continued:

"Look, this is the level of precision I need. Can you achieve that here?"

"Hehe, don't you even look where I am? If I can't make this, you can forget about making it in the whole of China!" Little Doe continued, head held high. Teacher Yuanjiu remained silent, only smiling.

"Huh? What! To achieve this level of precision?" Looking at the blueprints drawn by Teacher Yuan Jiu, Jiang Xia's ahoge finally slumped down.

Take a look at the sketch provided by the original artist. At first glance, it looks like a "stepped grating". But upon closer inspection, it is actually a semicircle, but this semicircle is not regular, with a 0.1 mm indentation in the middle.

In addition to this, it is also required that its surface have 300 uniform grooves per millimeter.

Little Dai Mao was in tears. "Boss, it would be better if you made it flat. At worst, you can just make a table-shaped engraving machine and put more effort into the lead screw, worm gear, and guide rail."

You've created a complicated, polyhedral thing; who are you trying to impress?

This means that not only vibration needs to be considered, but the temperature also needs to be properly controlled!

This would require bringing over a modern five-axis machining center to achieve. The precision requirements are comparable to those of a grating engraving machine.

Ok?

A grating patterner? Fiber optic transmission? A laser?

By the way, gratings can be used to modulate and split laser beams, and for things like optical path shaping, which seems quite useful.

Pooh!

I've gone off on a tangent; let's get back on track. Instead of focusing on those high-end machines, we should put more effort into five-axis machining.

Without computer assistance, a five-axis machining center would be prone to tool collisions in no time! The multi-axis linkage capability of a five-axis machining center is something that cannot be handled by humans. However, the integrated circuit is still being fine-tuned by Dr. Lan Ying, so we can't count on it for the time being.

If we were to directly intervene with the current "Big Yellow" (referring to a specific AI system), well, with that amount of data across five axes, it would be strange if "Big Yellow" didn't overwhelm it.

Current three-axis machining centers can only machine the sides or end faces of semi-cylinders. If multiple clamping operations are performed or special fixtures are used…

No, no, this won't work. While it's possible to machine it this way, the material deformation caused by temperature when cutting the cylinder will be difficult to manage. Let alone increasing the fluid delivery, for such high-precision components, deformation occurs the instant the tool contacts the material.

Well, there's no other way. After thinking it over, only a five-axis machine tool capable of processing complex curved surfaces can handle this task.

"I'm sorry, Mr. Yuanjiu. I made a boast; I can't fulfill your request for the time being..."

Little Ao Mao looked dejected and quite unwilling. The senior colleague had asked you to solve a problem, and you couldn't even make a single part for them...

Well, I originally thought that making a three-axis machining center would be enough, but who would have thought that a master's casual drawing could stump me...

Little Dai Mao was overwhelmed with an indescribable sense of frustration.

Well, it's not really the little ahoge's fault.

Why did so many amazing and talented people emerge back then, and so many groundbreaking ideas failed to be developed and popularized for various reasons?

However, it's not too late now. At least the spirit of our scientific researchers has been passed on, which has led to the emergence of various inspiring things.

We've digressed; let's get back to the topic.

Just as Jiang Xia was feeling frustrated, Teacher Yuan Jiu kept staring at the several robotic arms that Jiang Xia had drawn.

"Is this three linear axes and one rotational axis?"

"Yes, the rotary axis rotates around the X-axis (A-axis) or Y-axis (B-axis), which can achieve indexing or continuous rotary machining of the workpiece. But this four-axis thing is only suitable for machining circumferentially distributed holes and grooves..."

"The parts you need require two rotating shafts..."

How did you achieve automatic control?

"Programmed Numerical Control, of course!"

Teacher Yuanjiu glanced at Shousong sitting next to him and nodded slightly in acknowledgment.

Then he grabbed Jiang Xia's hand and said with a grin, "Eight years! Can you make this part in eight years?"

"Ahem~~" Jiang Xia coughed twice: "Eight years? Didn't you want it now?"

"Hey, I'm not stupid. Do you think it's possible to ask for it now?"

Jiang Xia slammed his head on the table: "You should have said so earlier! My brain is about to dry up!"

"Hehehe, isn't it because you were in a hurry? I didn't give you a timeframe, did I!"

Jiang Xia picked up his water glass and paused for a moment: "Eight years? No problem! Once I've finished developing the five-axis machine, the first part I'll make is the one you need!"

"Okay! It's a deal!"

"but……"

?

"Mr. Yuanjiu, did you used to work at Ford Motor Company?"

"Hahaha! Yes, that's right. I spent two years at Ford's scientific lab, conducting research on automotive automation control. What's up?"

"Hehehe! What a coincidence, I also have a question to ask you!"

As he spoke, Jiang Xia excitedly stood up and took out a row of blueprints from the wooden cabinet by the wall.

"I want to mold this big thing, but I need manpower. Could you do me this favor first?"

"Hahaha, well, so you were waiting for me here! Let's see what you've come up with!"

Unfolding the blueprints, Mr. Yuanjiu was somewhat stunned.

"Wow, so awesome!"

"This is?"

"Optimus Prime!"

"Great name! With this size, it really deserves the name if it's used to transport logs!"

Mr. Yuanjiu continued looking at the next drawing. "Hmm, why isn't the mechanical structure I imagined there? Instead, there's a bunch of furniture-like things. Eh? Is this the interior of the car? A sofa? This... is this a bed?"

"Wow! A two-meter-long bed! With a spring mattress! Luxurious, isn't it!"

"You inhuman brat! You're building yourself a palace!"
