Courtyard House: My Wife is Xu Huizhen

However, since the person had already left, He Yuzhu didn't think too much about it. Right now, it was more important to confirm the performance of the lathe.

Then they started making parts for testing, and as the testing progressed, He Yuzhu frowned.

The situation was somewhat different from what I had imagined. The lathe was successfully developed, but only half of it was successful.

The newly manufactured lathe can produce parts, but the precision does not meet He Yuzhu's requirements, making it feel like a semi-finished product.

He Yuzhu made three parts in a row, and the results were all the same, which shows that it was not an occasional phenomenon, but a problem with the machine itself.

After washing the dishes, Xu Xiaomei came to the door of the small warehouse, coughed, and then, without going in, asked:

"What's wrong? Didn't you just say it was done?"

He Yuzhu sighed and said, "The lathe can be used, but it's a bit different from what I need."

The kiss just now was just an accident, and Xu Xiaomei chose to forget it. Of course, He Yuzhu wouldn't bring it up again, as if nothing had happened.

"Let's go back. It's getting late. We can think about things tomorrow. Maybe we'll find the answers tomorrow if we can't figure them out now."

"Alright, I'll pack up and then we'll go back."

He Yuzhu didn't dwell on it. He tidied up his things, soaped his hands, and came out to see that it was raining. He asked, "When did it start raining?"

"You left work not long after you got off work. You were probably too focused to notice."

After speaking, Xu Xiaomei opened the yellow bamboo umbrella in her hand and said, "I searched everywhere and only found this one umbrella."

He Yuzhu was surprised and said, "No umbrellas?"

"No, I've seen your office too."

He Yuzhu felt a little sad. If there was only one umbrella, the two of them would have to share it to go home.

Normally it wouldn't matter, but the two of them had a small accident just now, so sharing an umbrella together is a bit awkward.

He wanted to go into the office and take another umbrella from his storage space, but Xu Xiaomei had already looked for one, so that method was no longer an option.

Xu Xiaomei stamped her foot and said angrily, "If I'm not afraid of my brother-in-law, what are you afraid of?"

He Yuzhu was actually just worried about Xu Xiaomei, so since he said that, he stopped worrying about it.

They picked up the yellow bamboo umbrella, opened it, and Xu Xiaomei crouched under it. The two locked the gate and then hurried back, stumbling along the muddy path.

At first, the two kept some distance from each other, but the dirt road was too difficult to walk on, and they soon stumbled and bumped into each other from time to time.

In addition, the rain was falling at an angle, and in order to avoid the rain, they couldn't care less. Sometimes, in order to prevent Xu Xiaomei from falling, He Yuzhu had to support her.

By the time Xu Xiaomei and the others realized they were being held in He Yuzhu's arms, a considerable amount of time had already passed.

She was too embarrassed to struggle any further, and just told herself that this was her brother-in-law, and that he was only trying to avoid the rain.

The most difficult part of the road was outside the city. It turned into a muddy mess after it rained. Fortunately, we soon entered the city. The main streets were paved with asphalt, and even the alleyways were paved with thin flagstones.

At this point, Xu Xiaomei took the opportunity to break free from He Yuzhu's embrace, her face flushed red, like a ripe green apple.

He Yuzhu also became more sober. Xu Xiaomei was still young, just turned 18, so it was best not to provoke her anymore.

And so the two of them carried the yellow bamboo umbrella back to their doorstep.

Xu Xiaomei finally breathed a sigh of relief. On the way, she was worried that He Yuzhu might do something to her. Without saying goodbye, she rushed into the yard.

The next day at work, the two resumed their polite and ordinary colleague relationship, except that Xu Xiaomei would sometimes space out and think about some embarrassing things.

He Yuzhu didn't have that much free time. The most important thing right now was to solve the precision problem of the parts. After studying it for a long time, he still couldn't find a solution, so he went to the heavy machinery factory and found Tong Zhi.

But he didn't believe it at all, and asked in surprise, "You said you used those machines to rebuild a lathe?"

"Yes!"

"It's a liar!"

Why would I lie to you? Why don't you go and see for yourself?

"Okay, wait for me after get off work."

Tong Zhi thought to himself, who cares if it is or not, anyway, he can get a free meal cooked by He Yuzhu when he goes there at noon.

After get off work, Tong Zhi called Da Zhuang, and the two of them eagerly followed He Yuzhu to the machinery factory.

The two men were stunned as they looked at the brand-new machine tool in front of them. Da Zhuang asked:

"I said, which factory produced this? Why isn't there a nameplate?"

"I said I made it. Look, there are a few spare parts here."

As He Yuzhu spoke, he pointed to the shelf. The two looked up and saw that there were indeed several commonly used parts on lathes, which they hadn't noticed when they came in.

"Did you really make this?" Tong Zhi asked.

Why don't you believe me?

"No, you've only been learning machine tools for a few months? You're telling me you can build a machine tool by yourself?"

"I've been studying for a long time. Besides, I'm a genius. I can grasp things very quickly, so of course I learn things fast."

Tong Zhi pursed his lips, unable to refute He Yuzhu's words.

When I taught him to read blueprints and design manufacturing processes, he did learn very quickly, which made me quite envious.

I never imagined that I could grow to this level in just a few months and be able to manually build a machine tool.

"Fine, even if you did it, then you've come here today just to blatantly show off?"

"Didn't I say that although the lathe I made is usable, the error is a bit large?"

"Let me see."

After Tong Zhi finished speaking, he clamped a workpiece onto the lathe and started it up. After it was finished, he measured it again, and sure enough, it was different from the new lathe. It felt like he was using an old lathe.

"Oh, that's strange. Logically, this shouldn't happen."

"Yes, that's why I asked you to come and help me figure out what the problem is."

Although He Yuzhu acquired the relevant knowledge, it was like someone learning from a book; he didn't have much relevant experience.

He only knew how to follow the steps, but when problems arose and there were no answers in the book, he was completely lost.

"This is the first time I've encountered this problem either. The finished product should look brand new, but yours looks old instead!"

Da Zhuang asked, "By the way, where are your blueprints? Is there something wrong with them?"

The three of them arrived at the office. He Yuzhu tossed the blueprints he had made to the two of them and then turned and went to the kitchen.

There was no way to ask them both to come and help, since we had to provide meals, so I had to cook for myself.

After the four dishes and one soup were prepared, the three of them ate and chatted. Da Zhuang and Tong Zhi were also worried because the blueprints seemed to be fine.

Tong Zhi asked, "Which organization can I get these drawings from?"

There's no concept of intellectual property rights now, especially since the whole country is working together as a unified whole, all for the sake of national development.

Therefore, a lot of knowledge is publicly available. For example, He Yuzhu could easily get the blueprints for diesel engines from the heavy machinery factory.

He Yuzhu said, "I drew this myself. I disassembled a lathe, measured all the parts one by one, and then remade it according to the dimensions."

Upon hearing this, Tong Zhi couldn't help but laugh. He had a mouthful of wine in his mouth and quickly turned his head.

"Pfft!" It all sprayed onto Da Zhuang's face.

Da Zhuang reached out and touched it, shouting in authentic Sichuan dialect:

"I'm telling you, if you don't want to drink, then don't drink. We can't waste it!"

Then he got up and went outside to wash his face again.

Tong Zhi asked with a smile, "You used this old lathe for reverse engineering?"

Reverse engineering, also known as reverse engineering, involves re-measuring and mapping all components using physical objects without design drawings.

Producing according to the blueprints is called reverse engineering.

Since the founding of the People's Republic of China, the West has imposed an embargo, and many products were manufactured by obtaining blueprints through reverse engineering.

He Yuzhu nodded: "Yes, is there a problem?"

Tong Zhi laughed and said, "You got the first step wrong. Others use new machines to do reverse engineering, understand?"

He Yuzhu slapped his forehead, suddenly realizing that he had indeed made a mistake.

Others who do reverse engineering take a new machine, measure each part, and then produce it. If the parts are manufactured to quality and assembled together, it becomes a brand new machine.

But my first step was to reverse engineer using an old, secondhand lathe.

When reverse engineering, I forgot to consider wear and tear, and just mechanically produced according to the dimensions after wear. As a result, the lathe I made will have errors.

As the saying goes, "a lamp cannot be lit without a lamp," and once this thin layer of paper was pierced, He Yuzhu understood.

If it weren't for Tong Zhi's explanation, I would have gone astray by always suspecting the problem was somewhere else.

Perhaps after some time I will understand this principle, but that will cause delays, and I may never find the reason.

"You're more experienced."

"Don't say that. Experience can be accumulated, but you have talent."

When Da Zhuang returned and learned the reason, he was amazed, wondering why he hadn't thought of it.

After dinner, the three of them gathered around the blueprints again, looking for errors and making corrections.
