Chapter 9 Field Programming
what happened!

There seems to be a problem!
The crowd of onlookers who had basically calmed down suddenly became agitated, and the buzzing sound of discussion rang out again.

"Let me just say it, Xiaoma has participated in training, how can Lin Feng know how to operate it?"

"It's over, it's over, the leader of the head office is standing by."

"."

Of course, these buzzing voices also reached the ears of Wang Tianfang, Jiang Haitao and others, and their faces became solemn, and even Wang Tianfang's eyes were still inquiring.

What is going on here?
Lin Feng frowned slightly, and then quickly flipped through the several NC programs stored in the machine tool. There was nothing wrong, there was no NC machining program for the axial flow impeller of the turboshaft Bajia engine.

The existing programs are relatively short. One program has only a dozen lines, and the longest program has only dozens of lines. These NC programs must be written by the machine tool manufacturer, and the purpose is mostly before leaving the factory. Give this machine a try.

Facing Jiang Haitao's anxious inquiry, Lin Feng did not answer immediately, but replied after reviewing these programs, "Director Jiang, as for the NC program we process the test piece, I checked and there is no such program in the machine tool. .”

At this moment, everyone understood.

It turned out to be a false alarm!
It turned out that Lin Feng frowned slightly because he did not find the corresponding CNC machining program in the machine tool.

Heaving a sigh of relief quietly, Jiang Haitao said loudly, "Where is Maggie, where is he?"

What he meant was obvious. If there was a corresponding CNC machining program, just ask Maggie. How could he know? I didn’t see Maggie when I looked around.

A voice replied, "Director Jiang, Ma Ji left as soon as he found it, and is not here."

It turned out that Ma Ji had left a long time ago, didn't this Ma Ji know how to stay and learn how Xiao Lin operated? Jiang Haitao was very upset with Ma Ji.

How to process the test piece if there is no CNC machining program?

This is a big problem. I originally thought that Maggie had prepared everything. At the critical moment, since there is no CNC program, this is nonsense.

Jiang Haitao asked, "Xiao Lin, take another look to make sure it's really gone."

Lin Feng replied affirmatively, "You don't need to look any further, there are only a few programs in it, I have read them all, and there is no corresponding NC program for processing the test piece at all."

what!
There is really no corresponding CNC program!
At the critical moment, this kind of chain was actually dropped.

Jiang Haitao and Yan Bing looked at each other, and they both saw each other's embarrassment. How can they continue playing? Deputy factory director Wang and Chief Technologist Deng of the head office are all waiting to see What about the processing of the test piece?

When the two of them didn't know what to do, Lin Feng's voice sounded, and he said with a relaxed face, "There is no CNC program, so it's not a big problem, I can program on site."

what!
Live programming! ! !

Kobayashi, are you so good!
Yan Bing and Jiang Haitao were pleasantly surprised, thinking they heard it wrong, like two drowning people, when they were exhausted after splashing on the water, someone suddenly threw a life jacket over.

What a surprise!
The two of them instantly lightened up!
Deng Shaoyuan is an expert in mechanical processing, and of course he is not a layman in CNC machining. He has some understanding, he can't help reminding, "Young man, the blade shape of the axial flow impeller is very complicated, and such NC programming is a big job. You It’s really possible to program on the spot.”

Even in the face of such a great leader as Deng Shaoyuan, Lin Feng did not feel nervous or restrained at all. On the contrary, with a relaxed and confident face, he replied, "Leader, I don't think it's a big problem, but you may have to give me three or four 10 minutes."

Deng Shaoyuan was surprised again. Such a complicated CNC machining program only takes three or four 10 minutes. He wants to see if the young man is bragging.

Lin Feng didn't talk nonsense, he called up the programming panel under everyone's gaze, and prepared to write the program line by line.

There are currently two ways to input the NC program of the machine tool. One is to program it in advance on the computer, and then copy it to the machine tool with a [-]-inch floppy disk.Another method is to program directly on the machine tool.

Generally speaking, the NC machining program written directly on the machine tool is relatively simple and short, with a length of more than ten lines, at most dozens of lines.

The shape of the blades of the vortex eight-armed axial flow impeller is very complex, and there are complex curved surfaces that meet the aerodynamic requirements. It is a big problem to process such blades. A five-axis linkage CNC machining center must be used. Of course, the corresponding CNC programs are also very difficult. Complicated, with a length of hundreds of lines.

Jiang Haitao saw that Lin Feng was about to start on-site programming, and immediately shouted loudly, "Hurry up and get the design drawing of the axial flow impeller."

How did you know, Lin Feng smiled, "No need, I remember the size parameters of the axial flow impeller."

what!
You all remember! ! !

You don’t even need the design drawings, is it so powerful? This is an axial flow impeller with complex blade profiles, and the size parameters are also very complicated, and they are all memorized in your mind.

Jiang Haitao was still a little worried, so he asked someone to bring the design drawings and spread them out on the large work table next to the machine tool, and many people gathered together.

"Oh grass, it's so complicated!"

"My God, the blade shape is so complicated, the NC milling NC program of the blade is probably not simple!"

"Look, Lin Gong didn't look at this design drawing at all, and just programmed it on the spot like this, it's amazing!"

"........."

At the beginning, Lin Feng's input speed was not fast, mainly because the input keyboard of the machine tool was a little different from the keyboard of the computer.

Gradually, probably within three to five minutes, Lin Feng's input speed increased significantly, crackling, fingers flying.

This speed is dazzling!

The point is, Lin Feng has never looked at the design drawings. Could it be that the multi-size data is really in his mind.

Cow batch!

Too awesome! ! !

The workers and technicians onlookers were all overwhelmed with admiration, and even Wang Tianfang nodded, feeling a burst of relief in his heart!
He feels that he has more face!

At least in front of Deng Shaoyuan, Lin Feng was proud of him. Yesterday he bit the bullet and patted his chest to ensure that there was no problem with the processing of the test piece.
Our Kobayashi is amazing, he's so embarrassing!

Deng Shaoyuan is an expert in mechanical processing. He was slightly surprised when he saw that Lin Feng was actually programming on the spot. After realizing it, he walked to Lin Feng's side and carefully looked at the NC program written by Lin Feng.

From time to time, he would take a look at the design drawings to check the correctness of the NC program. Gradually, his expression changed.

　Comrades, don't forget to vote!
