The system removes all contact moving surfaces of the equipment in order to achieve the highest level of surface roughness. "www.biquge.info Tian Ze gave the first order.

"Drop! Receive the command and start the analysis. ”

"Drop! If you use the removal function on all contact moving surfaces of the equipment, the volume to be removed will account for 0.5% of the total volume of the equipment, and the removal conditions are met, so start executing the removal command now, and the removal progress is 1%, 2%, and 3%, ...... "This time more than a minute passed, and the PS system confirmed Tianze's order.

As the readings progressed, the rolling machine looked unchanged.

It is still the same, whether it is the cold rolling machine placed in the factory or the cold rolling machine in the hologram, there is no obvious difference with the naked eye.

In fact, the cold rolling machine is different.

The most obvious is the sound.

Yes, sound.

Before using the removal function, Tianze could clearly hear the sound of the motor running, and could clearly hear the loud roar of the machine parts rubbing against each other. It's not going to disappear completely, but it's getting weaker and weaker as the reading progresses.

When the reading was completely over, Tianze found that it was no longer so noisy.

This is one of the great benefits of the improved surface roughness of the part.

In fact, there is an invisible benefit.

That's energy saving.

The principle is simpler, if the rough accuracy of the internal contact surface of the cold rolling machine may be Ra0.2 before, then now it is Ra0.02, Ra0.002, Ra0.0002, or even smaller. When the contact surface is smooth, the friction coefficient is smaller, and the sound and energy consumption are naturally reduced.

Of course, no matter how much you reduce it, the rough accuracy will not completely become zero.

This is not because the PS system is not good, but because of the material limitations.

Upgrading the rough accuracy of the internal contact surface of the cold rolling machine, Tianze did not act immediately, but waited for the production of the next ferrule. When the ferrule was machined, Tian Ze immediately opened his mouth and ordered, "Compare the produced parts with the previously loaded part drawings." ”

"Drop! Start the comparison. ”

"Drop! After the comparison is completed, after comparing with the parts drawing, the dimensional accuracy of the workpiece IT13-IT11 and the surface accuracy Ra1.0 do not meet the requirements of the drawings at all. "In just three seconds, the PS system completed the comparison.

Damn, how can this be?

The surface accuracy Ra1.0 is well understood, and it is also under the control of Tianze. For example, if you use a glass plate and a wooden board to squeeze the dough at the same time, which one will be smoother? Needless to say, it must have been squeezed by the glass plates.

The question is why hasn't the dimensional accuracy improved?

Instead, it has decreased.

What's going on? What's going on? Tian Ze frowned, and kept asking himself in his heart. Why does the surface accuracy increase, but the dimensional accuracy decreases, and what is going on?

Size, size......

A flash of light flashed through my mind.

Damn, Tian Ze slapped his forehead.

How stupid!

The rough accuracy of the internal contact surface of the cold rolling machine has been improved, which does have many benefits, but it is not without harm! For example, there will be a lot of gaps between the contact surfaces, what will these gaps bring?

It must be a change in the production accuracy of the equipment, which is not only the dimensional accuracy, but also the change in shape accuracy, position accuracy, and interrelationship.

It may be good.

It can also be bad.

What to do? Would it be useful to fill in the gaps?

"The system repairs all the moving surfaces of the equipment so that there are no gaps between the parts of the equipment." Tian Ze gave the second order.

"Drop! Receive the command and start the analysis. ”

"Drop! If the repair function is used on all the contact moving surfaces of the equipment, the volume to be repaired will account for 1.2% of the total volume of the equipment, which meets the conditions for repairing, and now start to execute the repair command, and the repair progress is 1%, 2%, 3%, and ......" After more than a minute, the PS system confirmed Tianze's order.

As the readings progressed, the cold rolling machine looked like it was still the same.

In fact, it has changed, and the gaps that are invisible to the naked eye have disappeared one after another.

When the new ferrule was machined, Tian Ze immediately opened his mouth and ordered, "Compare the produced parts with the previously loaded part drawings." ”

"Drop! Start the comparison. ”

"Drop! After the comparison is completed, after comparing with the parts drawing, the workpiece dimensional accuracy IT13-IT12 and the surface accuracy Ra1.0 do not meet the requirements of the drawings at all, do you want to turn on the removal function of the system? "After three seconds, the PS system completes the comparison.

IT13-IT12？

Compared to IT13-IT11 just now, it is a little better.

But compared with before the transformation, it is still lower!

Tian Ze shook his head, naturally not satisfied with this result, and devoted himself to a new transformation.

……

IT10-IT9！

……

IT12-IT11！

……

IT8-IT7！

In a flash, it was night, but Tianze's transformation did not make much progress. What Tianze thought before was too simple, this is not a transformation of one part at all, but the transformation of dozens or hundreds of parts, and these parts are very related to each other, which can be said to affect the whole body.

Changing the size of a part will inevitably cause a change in the accuracy of the entire equipment.

To make matters worse, it's a combination change.

For example, if the size of Part A is modified alone, the accuracy of the entire equipment may be reduced, but the accuracy of the entire equipment will be improved by transforming Part A and Part B at the same time.

If the C part is remodeled, the accuracy of the whole equipment will be reduced.

It's that complicated.

In the end, Tianze came to a conclusion that it is not impossible to improve the accuracy of the equipment, but it is a bit taken for granted if you want to meet Tianze's expectations, and it is not much higher than winning the lottery.

Unless Tianze is given a supercomputer.

Relying on the computing power of supercomputers, we can eliminate and select the best combination from countless combinations. But this is a bit unrealistic, not that you can't afford a supercomputer, but it's too exaggerated.

Did you just give up?

Tianze is unwilling!

The accuracy of the equipment is improved a little, at most it is to reach the domestic advanced level, and there is still a big gap with the top international bearing enterprises, how can this result be satisfied with Tianze?

"What should I do?"

Tianze was worried.

While Tianze was pondering a solution, the phone in his trouser pocket rang. When he took it out and saw that it was actually Zhou Yu calling, Tian Ze's brows immediately furrowed. Just as he was about to answer the phone to bury Zhou Yu, Tianze's whole person was suddenly stunned, and then his face turned into ecstasy.

There you have it, there is a way.

"Tuhao, what are you looking for my brother?" In a good mood, Tian Ze answered the phone and said.

"Soil your sister!" Zhou Yu's roar was immediately transmitted.

"If there's a fart, let it go." Tian Ze laughed.

"Your sister, come out for a drink and celebrate!" Zhou Yu still said the purpose.

"No, I have something to do at night." Tian Ze refused without even thinking about it.

Smack, don't give Zhou Yu time to react.

Tianze hung up the phone.

Tian Ze is not fooling Zhou Yu, Tian Ze is really having something to do tonight, if it wasn't for Zhou Yu's phone call to wake him up, it is really possible that he has mistaken the right thing.

……

Buying a set of Barbie dolls, Tianze came to the apartment he had rented before.

"Brother, where's Lele's birthday gift?" Tianze just knocked on the door twice, and the door was opened, and he saw Lele shouting with joy on his face.

That's right, today is Lele's sixth birthday.

"Ahh Brother forgot. ”

Tian Ze said with a look of annoyance.

"It's okay, Lele is very happy that my brother can come." Hearing Tianze say that he didn't bring a gift, Lele's little face couldn't help but flash a trace of disappointment, but he was still sensible.

"Silly girl, even if my brother forgets everything, he won't forget Lele's things!" Tian Ze squatted on the ground, pulled Lele's little nose, took out his left hand hidden behind him, and said distressedly, "Look, what is this?" ”

"Barbie!"

Lele exclaimed.

"Do you like it?"

Tian Ze asked.

"I like it, Lele likes it so much." Let's go! Lele hugged the Barbie doll, and the disappointment immediately turned into surprise, and Tianze sneaked up on his face.

"Xiaotian, are you here?"

At this time, Qiu Xuejiao's inquiry came from the kitchen.

"Sister Qiu, it's me."

Tian Ze picked up Lele, closed the door casually, and replied.
