Chapter 109 Give up?

"The system removes all contact movement surfaces of the equipment in order to achieve the highest surface roughness." Tianze issued the first order.

"Drip! Received the order and started the analysis."

"Drip! If you use the removal function on all contact movement surfaces of the device, the volume to be removed will account for 0.5% of the total volume of the device, which meets the removal conditions. Now start to execute the removal command, and the removal progress is 1%, 2%, and 3%. ..." It took more than a minute this time before the ps system confirmed Tianze's order.

As the readings progressed, the cold rolling machine appeared to be unchanged.

It is still the same, whether it is the cold rolling machine placed in the factory building or the cold rolling machine in the holographic image, no obvious difference can be seen with the naked eye.

In fact, otherwise, the cold rolling machine is different.

The most obvious is the sound.

Yes, voice.

Before using the removal function, Tianze could clearly hear the sound of the motor running, and could clearly hear the huge roar of the machine parts rubbing against each other.Although it will not completely disappear now, it is weakening a little bit as the reading progresses.

When the reading was completely over, Tianze found that it was not so noisy anymore.

This is a great benefit of improving the surface roughness of parts.

In fact, there is an invisible benefit.

That is energy saving.

The principle is even simpler. If the rough precision of the internal contact surface of the cold rolling machine may be Ra0.2 before, it is now Ra0.02, Ra0.002, Ra0.0002, or even smaller.The contact surface is smooth, the friction coefficient is also small, and the sound and energy consumption are naturally weakened.

Of course, no matter how much it is reduced, the rough precision will not completely become zero.
This is not because the ps system is not good, but because of material limitations.

After upgrading the rough precision of the contact surface inside the cold rolling machine, Tianze did not act immediately, but waited for the production of the next ferrule.When the ferrule was processed, Tianze immediately ordered, "Compare the produced parts with the previously loaded part drawings."

"Drip! Start comparing."

"Drip! The comparison is complete. After comparing with the part drawing, the dimensional accuracy of the workpiece is IT13-IT11, and the surface accuracy is Ra1.0, which does not meet the requirements of the drawing at all. Do you want to activate the system's removal function?" It takes only three seconds, ps The system completes the comparison.

Damn, how could this happen?
The surface accuracy Ra1.0 is well understood and is under the control of Tianze.As a small analogy, use a glass plate and a wooden board to squeeze the dough at the same time, which one will make the dough smoother?Needless to say, it must have been squeezed by the glass plate.

The question is why the dimensional accuracy is not improved?
Instead it decreased.

what happened?what happened?Tian Ze frowned, and kept asking himself in his heart.Why is the surface accuracy improved, but the dimensional accuracy is reduced? What is going on?
size, size...

A flash of light suddenly flashed through his mind.

Damn, Tian Ze slapped his forehead fiercely.

How stupid!

The rough precision of the contact surface inside the cold rolling machine has been improved, which indeed has many advantages, but it is not without disadvantages!For example, there will be many gaps between the contact surfaces. What will these gaps bring?
It must be a change in the production accuracy of the equipment. This is not only the dimensional accuracy, but also the shape accuracy, position accuracy, and changes in the relationship.

It is possible to be good.

It could also be bad.

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

"System, repair all contact movement surfaces of the equipment so that there are no gaps between equipment parts." Tianze issued the second order.

"Drip! Received the order and started the analysis."

"Drip! If you use the repair function on all contact 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 repair. Now start to execute the repair command, and the repair progress is 1%, 2%, and 3%. ..." More than a minute later, the ps system confirmed Tianze's order.

As the readings progressed, the cold rolling machine seemed to remain unchanged.

In fact, it still changed, and the gaps that were invisible to the naked eye disappeared one after another.

When the new ferrule was processed, Tianze immediately ordered, "Compare the produced parts with the previously loaded part drawings."

"Drip! Start comparing."

"Drip! The comparison is complete. After comparing with the part drawing, the dimensional accuracy of the workpiece is IT13-IT12, and the surface accuracy is Ra1.0, which does not meet the requirements of the drawing at all. Do you want to enable the system's removal function?" Three seconds later, the ps system will The comparison is done.

IT13-IT12?

Compared with the IT13-IT11 just now, it has improved a little.

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

Tianze shook his head, naturally he was not satisfied with the result, and devoted himself to the new transformation.

……

IT10-IT9!

……

IT12-IT11!

……

IT8-IT7!

In a flash, it was night, but Tianze's great cause of transformation did not make much progress.Tianze's previous thinking was too simple. This is not the transformation of one part at all, but the transformation of dozens or hundreds of parts. These parts are closely related to each other. It can be said that a single move can affect the whole body .

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

To make matters worse, this is still a combination change.

For example, if the size of part A is modified alone, the accuracy of the entire equipment may decrease, but if part A and part B are modified at the same time, the accuracy of the entire equipment will be improved instead.

If the C part is modified again, the accuracy of the whole device will be reduced again.

It's that complicated.

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

Unless you give Tianze a supercomputer.

Rely on the powerful computing power of the supercomputer to exclude and select the best combination from countless combinations.But this is a bit unrealistic. It's not that I can't afford a supercomputer, but it's too exaggerated.

Did you just give up like this?

Tianze is not reconciled!

If the accuracy of the equipment is improved a bit, at most it will reach the domestic advanced level, and there is still a big gap with the top international bearing companies. How can this result satisfy Tianze?

"How to do?"

Tian Ze was worried.

When Tianze was thinking hard about a solution, the phone in his trouser pocket rang.He took it out and saw that it was Zhou Yu who called, Tianze frowned immediately.Just as he was about to answer the phone and bury Zhou Yu for a while, Tianze froze suddenly, and then his face turned into ecstasy.

Yes, there is a way.

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

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

"If you fart, let it go." Tian Ze laughed loudly.

"Your sister, come out and have a drink to celebrate!" Zhou Yu still stated his purpose.

"No, I have business tonight." Tian Ze refused without thinking.

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

Tian Ze hung up the phone.

Tianze wasn't fooling Zhou Yu, Tianze really had something to do tonight, if Zhou Yu's phone call didn't wake him up, he might have missed the job.

……

After buying a set of Barbie dolls, Tian Ze came to the apartment he rented out before.

"Brother, where's Lele's birthday gift?" Tianze just knocked on the door twice, when the door was opened, and Lele shouted happily.

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

"Ah! Brother forgot."

Tian Ze said annoyedly.

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

"Silly girl, even if my brother forgets everything, he won't forget about Lele!" Tian Ze squatted on the ground, grabbed Lele's little nose, and took out his left hand hidden behind his back, feeling distressed "Look, what is this?"

"Barbie doll!"

Lele exclaimed.

"Like it?"

Tian Ze asked.

"I like it, Lele likes it so much." Haha!Lele hugged the Barbie doll, her disappointment turned into surprise, and she slapped Tianze fiercely on the face.

"Xiao Tian, ​​are you here?"

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

"Sister Qiu, it's me."

Tianze picked up Lele, closed the door behind him, and replied.

Ps: Thanks to Baobaobi☆ for the reward, the poor monk robbed a color F of 100 starting coins.

Ask for recommendations and rewards.
