Super Weapon Exchange System

"Sandra, let's eat some food first." A voice came from her ear.

A very ordinary aluminum lunch box, which contains food from the canteen. Although Heribala and Sandra are considered senior cadres, they are not special. At the same time, there is no special canteen for cadres in the entire northern heavy truck factory. , Without any privileges, everyone is the same.

Heribala watched Sandra delve into it with such gusto. He was both happy and worried. If this goes on, will the body survive?

Sandra used a spoon to deliver food to her mouth while still thinking about the curve on the computer screen.

This software is too complicated. If you want to master it, you have to keep thinking about it. However, I have to say that the function of this software is too powerful. I am afraid that ordinary minicomputers are not able to handle this machine. The computing power must be very powerful.

Since coming to Han, Sandra has been impressed by Han’s food culture. Coming to Han, the food is so rich. It’s like a steak in Europa. The way here is even potatoes. Can actually cook! When I first came, Sandra had eaten potato shreds many times and was amazed.

Anyway, Sandra's salary is high, and he has visited almost all the delicious places in the entire Prairie City, not bad for money.

And now, in this rice is Sandra’s favorite sweet and sour pork loin. At this time, Sandra just pulled the rice and vegetables into his mouth indiscriminately, seemingly not caring about the taste at all, while eating , While continuing to study.

Finally, I knocked down the last carriage return, a set of complex impellers were input, and with this first model, it was easy to do it later.

"Well, what time is it?" Sandra asked.

"It's already one o'clock in the morning. I have already heated this meal." Heribala said, "Sandra, don't get tired. Just rest and study tomorrow."

"Well, okay." Sandra said as she ate the food into her mouth again and again, at this moment, there was a noise from the machine.

"Computer ability is too strong? I thought it would take a few hours. Now that the calculation is completed, I will start cutting?" Sandra looked at the machine and immediately put down the lunch box: "Darling, come over and tell You, I’m trying to manufacture the first turbine blade, which has a complex curved surface. It can be made at one time without changing the fixture. In the manual, this thing can even be driven by titanium alloy. It is too powerful. I will try with an aluminum ingot. ."

Through the small window here, you can see the tool inside, which is cutting, one by one metal strips leaping out from the inside.

The three-axis machine tool has three coordinate systems, namely the three-dimensional X, Y, and Z. This seems to be able to accurately position, but the five-axis machine tool has two more rotating coordinates, and the tool position is converted from the workpiece coordinate system to the machine tool coordinate system. , It takes several coordinate transformations in the middle.

This is a prerequisite for processing complex curved surfaces, and complex programming requires two other degrees of freedom.

At the same time, in addition to linear motion, this CNC programming also coordinates the related calculations of rotational motion, such as rotation angle stroke inspection, nonlinear error check, tool rotation calculation, etc. The amount of information processed is very large, and the CNC programming is extremely abstract.

It is difficult for ordinary people to master, and Sandra, I have to say, is a genius in mechanical processing.

The operation of five-axis CNC machining is closely related to programming skills. Only by repeated practice, programming and operators can master the necessary knowledge and skills.

In later generations, the lack of experienced programming and operators are a major obstacle to the popularization of five-axis CNC technology. Many domestic manufacturers have purchased five-axis CNC machine tools from abroad. Due to inadequate technical training and services, the inherent functions of five-axis CNC machine tools are difficult to achieve, and the utilization rate of the machine tool is very low. In many cases, it is better to use three-axis machine tools.

Now, looking at the scene inside, Sandra is also very excited, especially when she sees the conversion according to the program, it is even more delightful.

This is the charm of five-axis linkage. On the previous three-axis CNC machine tools, it was impossible to make a special impeller!

"Sandra, let's eat." Heribala said.

Sandra took the half-eaten lunch box and continued to prepare to eat. At this moment, suddenly, an error flashed out on the computer screen of joy.

"Damn it." Sandra put down the lunch box, watching the knives inside gradually stop.

what happened? What has gone wrong with what I have checked?

When I stopped inside, opened it, and looked at the workpiece inside, I saw that the impeller was processed into a rudimentary form, but there were holes in the middle of the blade.

It must be a mistake in programming!

For CNC machine tools, programming is very important. A slight defect may damage the workpiece, or damage the equipment. No mistakes are allowed.

Sandra bit her lip, I don't believe it, she has to start over and check the program again!

Sandra leaned on the console again, tapping her fingers on the keyboard.

Outside, the sky gradually brightened.

Fortunately, there was an office next to it, with a bed inside. Heribala rubbed his eyes and looked outside.

The other boxes have not been disassembled yet, only Sandra is operating on this machine. Even so, it has exceeded the limit.

Sandra's eyes were a little red. There were two broken blades beside her. There were mistakes on both sides. No, it must be successful this time!

I don't believe I can do you!

Sandra was like a chicken blood.

"Sandra, don't you plan to take a break?"

"Don't bother me." Sandra said, "I'm debugging."

As a result, Heribala had to leave, and a new day began, and it was time for a routine inspection in the factory.

Just walking out of the door, I saw Chen Yutong coming.

"Sister-in-law, it's so early." He Ribala is very strange. Qin Guan only went back last night and got up so early today?

"I'll take a look at Sandra to see how she plans to prepare for her wedding." Chen Yutong said: "Time is tight, you have to work hard, I can help you."

"Thank you sister-in-law." He Ribala looked at Sandra who was modifying the procedure and said: "She must have forgotten about the marriage now."

Chen Yutong walked in slowly, stood behind Sandra, and heard Sandra speak impatiently: "Now, no one will disturb me, I'm not free!"

"What about the marriage?" Chen Yutong asked.

Sandra patted her forehead sharply, no, forget it!
