Now, it was nightfall, and the foreign guests had eaten dinner and had gone back to the guest house prepared for them, but the foreign guest named Mia had come again.

She was wearing a grass-green dress, the skirt was very short, almost barely covering it, a belt in the middle was restrained, it looked very beautiful, her hair was not bound, it was draped over her back like that, she looked a little casual, and there was an indescribable demeanor.

Especially her feet, the most special, if you match the clothes, you should wear a long boots, the most matched, showing a tall figure, exuding a unique noble and elegant charm.

But she was wearing a pair of roller skates, yes, she almost slipped in that, and if you were not seen from a distance, it would be like that ghostly panning.

She slid gently into the place.

Because he came in from behind, he didn't alarm anyone, and Qin Zhenhua only felt a little surprised, and then went with the other party.

You can't delay time for a foreign guest, besides, you explain in Chinese, and the other party can't understand it, so you don't have to find mistakes.

With a smile on her face, Mia nodded to Qin Zhenhua, then found a place and sat down quietly, like that, it seemed that she was also going to come to the class.

When Qin Zhenhua lectures, there are often people from outside who come to listen to the lectures, and Qin Zhenhua does not object, everyone pursues knowledge, which should be encouraged, but a lot of things happened during the day today, so this night's lecture is only for the students of the real training class, and there are many empty places.

Just after Qin Zhenhua continued to explain for five minutes, several panting personnel from the factory's security department chased in, and when they walked in the door, they were a little at a loss, Qin Zhenhua waved his hand to them, and these people left with relief.

The woman suddenly broke in wearing roller skates, no one was guarded, and she could see that it was a foreign guest, and she didn't dare to disturb the other party, so she could only chase after her on a bicycle.

It's only here that we catch up.

Qin Zhenhua continued to explain on the podium, and Mia below was there to listen seriously, and even Qin Zhenhua was a little surprised, can this foreign woman understand?

However, although I can't understand these words, but the program written on the blackboard is a program, and these people must understand it, and then think about it, it should be no problem.

Qin Zhenhua guessed so.

Finally, the boring class was over, Qin Zhenhua put down the chalk and said to everyone: "Today's class is over, now, if you have any questions, you can ask them." ”

At the end of each day's lectures, Qin Zhenhua will set aside time for everyone to ask questions, after all, these courses are very jerky, and it is normal to have something that you don't understand.

And just after Qin Zhenhua finished asking this sentence, Mia in the back raised her hand, and Qin Zhenhua, who was stunned for a moment, you can be an auditor, at this time, why are you asking?

"Qin, I have a question, today you talked about the macro knowledge of half a class, I want to ask what is the practical effect of these." Mia in the back spoke, speaking in a somewhat strange tone, but in Chinese, yes, it was the kind of Chinese with a big tongue!

This Mia can actually speak Chinese? When I saw her last time in Germany, I obviously didn't know it, I knew that she could understand, would I still be so calm? Qin Zhenhua frowned.

At this time, the entire classroom was silent, and everyone didn't know when a foreigner came behind them.

This is the cow man, during the day, he refuses to let foreigners see his secrets, and when he teaches at night, this foreigner comes over again!

Many people have this thought in their hearts, and if it weren't for the discipline of the classroom, they would have muttered quietly.

At this time, everyone's eyes were full of admiration, and when they returned to their factories, they wanted to spread this story, an absolute good story.

Zeng Niu has already given a thumbs up below, look, this is called a capable person, people's technology, even foreigners admire, come to listen to the class in person, and there are questions to ask if you don't understand!

"This is a kind of programming skills of CNC machine tools, the so-called macro, in fact, is through a fixed format, the Z-axis as an independent variable, the X-axis as a dependent variable, establish a two-variable geometric relationship, and then apply, flexible application of macro, can greatly simplify the programming of CNC machine tools, such as the example just mentioned, we want to turn out an elliptical outline, but the system does not provide elliptic interpolation instructions, so can not be called directly, this time the macro can easily achieve the corresponding function."

Teacher, preaching and solving doubts, since others have questions, then answer them yourself, but the other party is also a programming master, why ask such low-level questions?

But in an instant, Qin Zhenhua had already thought of something, and continued: "Of course, CAD/CAM these special engineering software have become popular now, as long as the graphics are entered, they can be automatically programmed, but if we want to make our technology exquisite, we must understand the specific programming essentials, to understand the underlying code, which is something that a qualified CNC machine tool operator must master." ”

Mia nodded again and again, yes, you have to understand everything, no wonder the last time I was in Germany, people were able to directly control the underlying code, just because of their in-depth research!

Looking at Mia's suddenly realized expression, Qin Zhenhua wanted to cry helplessly in his heart, this is a swollen face and a fat man, only CNC machine tools are imported in China, and there is no supporting engineering design computer, if there is an Apple computer, if there is a suitable CAD program, who has nothing to do to study these codes?

It's inefficient, it's brain-burning, and it's completely worth the loss.

It's like a foolish emperor who heard that people were starving to death outside, and asked why he didn't eat minced meat? I want to eat, I have to have it, but without these, I can only operate it little by little on the simple buttons on the CNC machine.

Uncle Zhao must be pushed to the position of factory director, so that he can buy a personal computer and make it more convenient for him to conduct research.

Qin Zhenhua's thoughts had already flown far away.

"Since you don't have a problem today, let's stop here." Qin Zhenhua looked at the watch hanging on the wall, it was already ten o'clock in the evening, there were foreigners here today, and it was estimated that they were not so active.

announced the end of class, and then Qin Zhenhua walked to Mia's position: "Ms. Mia, you should go back, right?" Shall I send you? ”
