The two walked to Gu Fei's dormitory 326.

Now that school is approaching, Gu Fei's five roommates have all rushed back from home. At this time, they were playing games in a group, and when they saw Gu Fei coming in, they just said hello casually, and then turned their heads and fell silent in the game screen.

Gu Fei shook his head, not intending to disturb them. He picked up his second-hand notebook and went to the dormitory of 325 Pang Ansheng next door.

His notebook was bought from the previous seniors who had graduated, and it was very cheap but well configured, at least it was easy to run large CAD or CAM software.

The only drawback is that the heat generated by the machine is a little large. It's okay in winter, you can use it as a hand warmer, but it's the end of summer, and the weather is already hot, and it doesn't take long for this book to be opened, and the whole computer will be as hot as a stove, which is daunting.

In these years, as long as you don't chase new electronic products, computers are cheaper than mobile phones.

However, Gu Fei was poor and couldn't afford to get a new computer, so he had to do it himself. He took the time to design and make a water-cooled base in the wind and fire company, which was used to dissipate heat from the book. Been trying it for several days and it works really well. Pang Ansheng, who was looking at the side, sighed.

Both of them had computers in their hands, but when they decided to start designing, Gu Fei took out a blank piece of paper and a pencil from Pang Ansheng's bookcase, and drew a sketch of the mechanism's operation.

This kind of mechanism kinetic work diagram is very different from CAD. It can be drawn at hand, and there are no half parts on the whole drawing, usually just a few lines, sliding plates, and fixed points. It can be said that it is the first step in designing a machine, and the insider knows which direction to calculate at a glance, but the layman probably thinks it is a seesaw or stickman at a glance.

Gu Fei summoned Pang Ansheng, he pointed to the simple diagram he had drawn in a few minutes, and said, "Ansheng, you can take a look." This is a schematic diagram of the X-axis operation of the machining center. The motor drives the lead screw, and the lead screw carries the workbench. The two ends of the screw rod are limited, and the screw rod should be able to reverse after the workbench touches the limit switch. ”

Pang Ansheng was stunned.

GU FEI THOUGHT FOR A WHILE, HE PICKED UP THE PEN AND WROTE TWO 1000 WORDS UNDER THE DRAWING, AND SAID: "I WILL GIVE YOU TWO WORKBENCH PARAMETERS NOW, ONE IS THE MOVING PARAMETER 1000MM/M, AND THE OTHER IS THE STROKE OF THE WORKBENCH 1000MM." You go down and look for the database yourself, decide the output power of the fischer motor, the gear ratio of each drive group......"

Pang Ansheng nodded, but his face was a little bitter.

As a mechanical student, he is no stranger to any of this.

Gu Fei drew simply, and said it even more simply.

However, all kinds of parameters in it can only be determined after motion analysis, dynamic static analysis, and coordination analysis and calculation of various motions. After the analysis of these parameters is completed, various transmission gears or conveyor chains can be designed, and the corresponding mechanical parts can be drawn after a large and small calculation......

It's fair to say that the whole process is very complicated.

"Then what are you doing?" Pang Ansheng was a little impetuous, and couldn't help twisting his ass and asking.

Gu Fei smiled: "I have a lot of business. The whole machining center has at least three axes, and if you only design one, I have to design two more on top of you. ”

Pang Ansheng was speechless, he rolled his eyes, picked up his mobile phone and called out.

After half a ring, the door to 325's dormitory was slammed open. A tall, mighty, handsome Northeast buddy burst in panting.

"You called him just now?" Gu Fei turned his head and asked Pang Ansheng, who was smiling at Mimi.

Pang Ansheng didn't answer, just stood up and clapped his hands, and welcomed: "Amon! Good things are waiting for you." Come on, help me calculate a few parameters. ”

The Amon in Pang Ansheng's mouth is actually Lin Chunhui.

Gu Fei's class is 30 people, and if you count it carefully, almost 31 provinces and municipalities across the country have one each. When freshmen introduced themselves on stage, most of them would introduce their name and province from which province.

A person's name is usually difficult to remember, on the contrary, his provincial celebrity is well known. Therefore, for a long time, students used to call the name of the province as a personal name. And Lin Chunhui is from Neimeng, so everyone calls him Amon.

"Gu Fei, you two are really buddies, send charcoal in the snow. Lin Chunhui threw away his mobile phone, looked at the schematic diagram of the movement of the mechanism in front of the two, and was a little speechless with excitement.

Pang Ansheng on the side winked mischievously at Gu Fei.

Gu Fei suddenly suddenly, he patted Lin Chunhui's shoulder, and said with a smile: "Isn't it outside?

"Okay, help each other, help each other. The dignified class leader rubbed his hands with a smile, he carefully looked at the drawings in front of Gu Fei, and asked, "Old Gu, then what do you want me to do?"

Gu Fei talked about his idea, and when Lin Chunhui figured it out, he said: "The three axes of the machining center, the X and Y axes work in a similar way, and the Z axis is relatively troublesome. Not only does it move up and down, but it also swings left and right in a small area, and it also rotates as a spindle. I've seen a little bit more than you, it's relatively easy to understand, and the design should be quicker. ”

"So, Ansheng and Amun, you two help each other to design the X and Y axes, and I design the Z axis myself. Gu Fei commanded.

Pang Ansheng exhaled, and Lin Chunhui naturally had no objections, so the two squeezed aside and discussed in a whisper.

There is no sun and moon in cultivating immortals, and the same is true for design, and it is nine o'clock in the evening in a blink of an eye.

The three of them were a little hungry, so they packed up their dormitories and went downstairs to the many restaurants outside the school.

As soon as she left the side door of the school, a girl with a beautiful face and long hair and waist reached up to greet her and held Lin Chunhui's arm affectionately.

This bowl of dog food came suddenly. Gu Fei subconsciously took a few more looks, and suddenly felt that this girl was a little familiar, and couldn't help but ask Pang Ansheng, who was envious and jealous: "Ansheng, who is she?"

"An eye from the sixth class of our major. Pang Ansheng looked at Gu Fei in horror. He had a ghostly expression and said, "Old Gu, don't tell me you don't know her." ”

Eye-catching?

Gu Fei laughed dryly.

All he knew was that there were two golden flowers in their class, but he really forgot what they looked like. And the girl in front of her is from Class 6 next door, Gu Fei feels that it is already very remarkable.

"Woe to you. Pang Ansheng felt it and secretly gossiped to Gu Fei, "She is the ...... who cheated with Lin Chunhui."

Gu Fei wiped his sweat, glanced at the front of him a few more times, and had to sigh that this world is declining, and his sister's heart is not ancient. Such a graceful and classical girl didn't learn anything, but she actually learned to cheat! And let the teacher catch her.

"What did they get in the exam?" Gu Fei was a little puzzled.

Lin Chunhui's name is well. His parents have high hopes for him, and he himself has never forgotten to repay his parents' "Sanchunhui". I have been working hard in college for three years, and it can be said that my grades in professional courses are not as good as Gu Feilai's.

So Gu Fei couldn't understand what he was trying to cheat on.

"It is said to be Mao Xuan or Ma Zhe?" Pang Ansheng grabbed his head, and he didn't know it.

"......" Gu Fei spat out blood. He really felt aggrieved for the two people in front of him.
