"Sandra, have some food first." a voice came in my ear.

It's an ordinary aluminum lunch box. It contains meals from the canteen. Although Bala and Sandra are senior cadres, they don't make any special. At the same time, there is no special canteen for cadres in the whole North heavy truck factory. There is no privilege. Everyone is the same.

When Barra watched Sandra delve into it with such interest, he was both happy and worried. Can he bear it if it goes on like this?

Sandra was still thinking about the curve on the computer screen while she was delivering food to her mouth with a spoon.

This software is too complex. If you want to master it, you must constantly think about it. However, it has to be said that the function of this software is too powerful. I'm afraid that ordinary minicomputers can't do it. The computing power of this machine must be very powerful.

Since she came to the Han country, Sandra has been impressed by the food culture of the Han country. When she came to the Han country, the food is too rich. Where it is like in Europe, it is steak. The practice here can even fry potatoes! When she first came, Sandra ate shredded potatoes many times and was amazed.

Anyway, Sandra's salary is high. She has visited almost all the delicious places in the whole grassland city. It's not bad for money.

Now, in this meal, there is Sandra's favorite sweet and sour tenderloin. At this time, Sandra just casually pulls the rice and vegetables into her mouth. It seems that she doesn't care about the taste at all. She is still studying while eating.

Finally, I knocked down the last enter. A complex set of impellers was input. With this first model, it would be simple to do it later.

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

"It's already one o'clock in the morning. I've warmed up the meal." he ribala said, "Sandra, don't be tired. Take a break and study it tomorrow."

"Well, OK," said Sandra, eating the food into her mouth again and again. Just then, there was a noise in the machine.

"Computing power is too strong? I thought it would take a few hours. Now the calculation is completed and the cutting begins?" Sandra looked at the machine and immediately put down her lunch box: "Darling, come here and tell you, I'm trying to produce the first turbine blade with complex curved surface. It can be made at one time without changing the fixture. In the manual, this thing can move even titanium alloy. It's too powerful. I'll try an aluminum ingot first."

Through the small window here, you can see that the cutting tools inside are cutting, and metal strips leap out from inside.

The three-axis machine tool is a three-dimensional coordinate system, i.e. x, y and Z in space, which seems to have been able to accurately position, while the five axis machine tool has two more rotation coordinates. The tool position is transformed from the workpiece coordinate system to the machine tool coordinate system, and several coordinate transformations are required in the middle.

This is the premise of machining complex surfaces. To carry out complex programming, it is necessary to have another two degrees of freedom.

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

Ordinary people, it is difficult to master, and Sandra, I have to say, is a genius in machining.

The operation of five axis NC machining is closely related to the programming skills. Only through repeated practice can the programming and operators master the necessary knowledge and skills.

In later generations, the lack of experienced programming and operators is a major resistance to the popularization of five axis NC technology. Many domestic manufacturers have purchased five axis NC machine tools from abroad. Due to the lack of technical training and services, the inherent functions of five axis NC machine tools are difficult to realize, and the utilization rate of machine tools is very low. It is better to use three-axis machine tools on many occasions.

Now, looking at the scene inside, Sandra is also very excited, especially when she sees that the conversion starts according to the program.

This is the charm of five axis linkage. It is impossible to make a special impeller on the previous three-axis NC machine tool!

"Sandra, keep eating," he zhibala said.

Sandra took the half eaten lunch box and continued to prepare to eat. At this time, suddenly, a mistake and joy flashed on the computer screen.

"Damn it." Sandra put down the lunch box and watched the knife stop gradually.

What's the matter? I've checked it. What's wrong?

Wait until it stops, open it, look at the workpiece inside, and see that the impeller has begun to take shape, but there are holes in the middle of the blade.

It must be a programming error!

For CNC machine tools, programming is very important. If there is a slight defect, it will damage the workpiece and the equipment. No mistake is allowed.

Sandra bit her lip. I don't believe it. I have to start over and check the procedure again!

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

Outside, it was getting brighter.

Fortunately, there is an office next to it. There is a bed in it. Someday Bala rubbed her eyes and looked outside.

Other packing cases have not been disassembled. Only Sandra operates on this machine. Even so, it has exceeded the limit.

Sandra's eyes are red. There are two broken leaves beside her. There are mistakes on both sides. No, we must succeed this time!

I can't believe you!

Sandra is like beating chicken blood.

"Sandra, aren't you going to take a break?"

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

So, when Bala can only leave, a new day begins. It's time for routine inspection in the factory.

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

"Sister-in-law, it's so early." when Bala was surprised, Qin Guan only went back last night and got up so early today?

"Let me see Sandra and see how she plans to prepare for her wedding." Chen Yutong said, "time is tight. You have to be busy with your work. I can help you."

"Thank you, sister-in-law." he ribala looked at Sandra who was revising the program and said, "she must have forgotten her marriage now."

Chen Yutong walked in slowly and stood behind Sandra. He heard Sandra speak impatiently: "don't bother me now, I'm not free!"

"What about the marriage?" Chen Yutong asked.

Sandra slapped herself on the forehead. No, I forgot!
