Engineer Cheolwoo Lee (4)
“Yes? You know this just by looking at it? Captain Kim, is that possible?”
“… that would be impossible?”
“Crazy, what the hell are you doing?”
They said with puzzled expressions.
“I’m Lee Cheol-woo.”
“No… I didn’t ask for your name.”
“Really, it’s just a name.”
“Thank you Mr. Lee Cheol-woo. Thanks to you, I was able to fix it properly.”
“no.”
And the boss who was watching it came to me and talked to me.
“Oh, did Cheol-woo find the cause?”
“Yes. I happened to see it.”
“I’m sure you have the ability. You’re amazing.”
“no.”
“Thanks to you, it’s been less likely to break down. If you need help in the future, feel free to let me know.”
“Oh, come to think of it, there are some parts I need. Can I use them after this milling machine is fixed?”
Come to think of it, if I didn’t have it, I could just make it.
The factory here was lined with machines capable of processing metal.
“… Uh, that’s a little difficult.”
No, just tell me everything you need.
“…”
“Because it’s out of order, I have to deal with the backlog now. I’ll take care of that and then take action so that you can use it.”
“yes.”
I can’t help it.
After a while, the people at SSCNC fixed and test-tested all the milling machines.
“Oh, that works. I think that’s probably what caused it to break over and over again.”
“Yes, thank you. Lee Chul-woo. Here is my business card. If you need any help next time, please feel free to contact me.”
“Ha ha, yes I understand.”
“Boss, let’s go.”
“Yes. I had a hard time.”
As they go, the worker gets up and begins to exercise restraint.
I didn’t have the materials I needed right now, so I watched the workers work.
The one processed with the milling machine is similar to a triangle, but with some protrusions. I worked on it by changing the settings more than three times.
‘hmm… … . Why do you do that?’
Having to change the settings 3 times was time-consuming and inefficient.
I’m sure you can cut it down with just two settings.
“Hey, can I work for a while?”
“Yes? Cheol-woo?”
“Yes. I have nothing to do right now.”
“…… Um, can you do it? Well, I’m remodeling that milling machine, so it should be this easy. But um…”
The worker spoke in a worried tone. It would have been difficult to entrust it to someone I didn’t know.
“You just saw it. It’s as if I fixed this. Can you give me a minute? I’ll make it a lot faster.”
“Yes? Make it faster to build? How is that possible?”
“I think we need to modify the PLC program a little bit.”
The setting of the milling machine was to set the rules on how to cut, and it was similar to the program, but a little different.
To be more precise, a PLC. It is a programmable logic control device.
“Uh… Really? I don’t know, so won’t the boss scold me?”
“Don’t worry. I’ll tell you well.”
“Um, I don’t know.”
After he said that, he moved out of his seat.
“It will take a while. Please wait a moment.”
After saying that, I immediately went to modify the setting PLC program of the milling machine.
“It’s done. Two rounds will be enough now.”
The milling machine was operated with the immediately changed setting.
Then, as I expected, the machining was completed in just two passes without the need to change the setting three times.
“…?”
“Isn’t it much easier this way? Faster?”
“No…… You said it was possible to process it like this? What on earth did you change?”
“I just told you. I changed the PLC program.”
“Ah, that’s right. Then the people who made the program before are idiots? Why did you let this method work and make it that way?”
“ha ha ha…….”
oh well, maybe i didn’t do it right

“Boss! Boss!”
The worker found the boss again.
“What is it again this time? Why do you keep calling me?”
“Listen. Mr. Cheol-woo reduced this work from 3 times to 2 times.”
“Eh? What do you mean? Work is reduced.”
“Look.”
The worker ran the milling machine exactly as I had set the program. The result was produced in just two strokes.
“Huh? This happens twice?”
“Yes. Mr. Cheol-woo did it.”
“No, the boss said this setting is the most optimized?”
“Who is the boss?”
“Yes. Someone who specializes in making PLC programs.”
“I don’t think so.”
“I don’t think so. Did Mr. Cheol-woo change this PLC program?”
“Yes. I was watching from the side, but I couldn’t understand. Why is it doing that? So I changed it a bit.”
“and…….”
The boss opened his mouth wide in admiration.
“Really, I thought Changsu was quick to understand, but… I really didn’t know it would be this great. I understand now that the milling machine is remodeled.”
“hahahaha, no. I’m trying.”
“Let’s see if we do this… It will save a lot of time. Mr. Cheol-woo, you said there was something to be processed, right? You can use it as much as you like.”
Oh, by helping you get help.
“hahahaha, can I?”
“Of course. Thanks to Mr. Cheol-woo, I was able to save a lot of time. In addition, I was able to easily meet the backlog. Thank you.”
“No. I’m more grateful. Then, sorry, can I write a little faster first?”
“Yes. Of course.”
I immediately started to carve out the metal parts I had in mind.

‘No, really, what the hell is that friend?’
Changsoo’s father thought.
When I heard that his son, Chang-soo, had a friend who was a genius, I couldn’t help but think, ‘Well, he’s still a student’.
Then, not too long ago, I went on a field trip to the factory. I thought he was a bit smarter because he was quick to understand.
By the way, the image of Cheol-woo that he showed today was not inferior to being called a real genius.
‘No, how did you know the cause of the milling machine’s failure?’
The milling machine, which broke down once every two months at the latest and once a month at the earliest, was a nuisance. There’s no refund for that either.
However, Cheol-woo recognized the cause of the breakdown at once.
With that alone, I felt that I was not a normal student, but the behavior after that was even more spectacle.
‘No, changing the setting from 3 times to just 2 times?’
That must have been crazy.
Previously, he had made four setting changes. Then, due to the lack of supplies, we entrusted the program to a company known for being good at PLC programming.
As a result, it was reduced to three times.
however… … . What is that, a friend named Cheol-woo changed the setting from 3 times to just 2 times as soon as he saw it with his eyes.
‘really… … . You’re a genius.’
As Changsoo said, he was truly a genius.
‘It’s not like this, I’ll have to go find the boss.’
Chang-soo’s father wanted to know a little more detail, so he went to the president who optimized the PLC program.
“Hello, Mr. Kwon.”
“It’s been a while? Mr. Yoon? You said you’ve been having a hard time lately? The deal with Toyo’s car was cut off.”
“Ah, there was a little bit of something like that.”
“Well, now that it’s delivered to Hyeonseong, should I say it’s better? Hmm… Well, anyway, why did you come here?”
“Have you recently entrusted a PLC program?”
“Yes. I definitely cut it from 4 times to 3 times.”
“Yes. I want to show you that program once.”
“Yes? What do you mean?”
“Take a look.”
President Yoon handed over the memory containing the program to President Kwon.
“Is it a PLC program?”
“Yes. That’s right. Take a look. The one the boss made and the current program.”
“Well, what’s different? Let’s take a look.”
President Kwon began to watch the program carefully.
“uh?”
“Isn’t that strange?”
“No, it’s not strange… you programmed it like this? Huh?”
“why?”
“This, doesn’t it work like this? I think it’s going to get stuck on the X-axis. Maybe it’s not.”
President Kwon said with a strange expression.
“How is it?”
“I do not know.”
“yes?”
President Yoon was taken aback, perhaps not knowing that President Kwon would say that he was not sure.
“What do you mean by that? You don’t know, aren’t you an expert who is rumored to be the best here in Busan, but you don’t know. What is that…”
“No, if it’s programmed this way, obviously. Uh… no. I don’t know either.”
“president?”
“Even if I’m popular in Busan, what I don’t know is what I don’t know. Isn’t it made by masters from Seoul or around the world?”
He could only assume that the program was created by a person of a much higher level than himself.
In reality, Cheolwoo could be at a higher level.
“hmm…….”
“I think you’ll know it when you actually operate it. It looks like there will be errors along the way… but why are you showing this to me?”
“Actually, I came here because I wanted to ask what happened.”
“What is that? Didn’t you leave it to another expert?”
“No, it’s a program modified by my son’s friend… It was processed in just two attempts.”
“Yes? It was possible to process it in just two rounds?”
“Yes. So… I know that friend’s PLC program is not good at handling it, but I was curious and came to find out what happened, but even President Kwon didn’t know.”
“…… No, what is it? A friend of the boss’s son?”
“yes.”
“That friend… why the hell can you make a program like this?”
“My son says he’s a genius.”
“Genius… I guess that’s right.”
* * *
After being able to use the resources of Changsoo’s father’s company to some extent, they were able to manufacture many parts in-house, and as a result, the work went smoothly.
“Huh, it’s hard.”
I tightened the last screw and spat out my words to myself.
It was not simply a matter of changing to a free vector gear. The firmware that runs the internal PLC program had to be modified, and even the board related to it had to be modified.
In fact, it was like making a new one.
“Did you make it?”
After hearing the news that it would be completed today, Changsoo came to visit us.
“Oh, I think it’s all made up.”
“How is it? Do you think it will work?”
“Maybe? Wouldn’t it work? There was no particular problem. Let’s do it right away.”
First, switch on the machine.
Gying- Gying-
The motor sounded and the milling machine began centering the lathe.
“I think the initialization is complete. Next, we need to put in the PLC program.”
“okay?”
“Yes. I’ll try right away.”
I connected the laptop and the milling machine, and entered the program I had made before.
Some English came out on the green window of the machine, and the phrase ‘complete’ was printed at the end.
“The program is OK.”
“What should I do next?”
“Let’s see next time…… I need to put in the processing ingredients.”
I also prepared this in advance.
A small cylinder of material made of steel was placed on the lathe of the milling machine.
“I’m ready with this. Now I just need to actually activate it.”
“for a moment.”
“why?”
“It’s just that we can’t see this kind of spectacle. I’ll get my dad.”
“……. okay.”
After a while, Chang-soo called his father, and Chang-soo’s father looked at the milling machine I had remodeled with curious eyes.
“Really, is it complete? Can you make a free vector gear at once with this milling machine?”
“If it works well.”
“Wow, you really make this. Really, it couldn’t have been easy.”
“Ha ha… no.”
It seemed ready now.
“Then let’s make it work.”
