When NC apprentices have a task system

Chapter 5 Xu Hui's Programming Teaching

Xu Yang was taken aback when he heard the words, and suddenly his eyes lit up and said: "It's true!"

Xu Hui said seriously:
"Of course it's true, why did I lie to you?"

"great!"

After receiving Xu Hui's confirmation order, Xu Yang showed an unconcealable excitement on his face.

7 months, more than 200 days.

Your hard work pays off, apprentice!
Brother can finally get in touch with programming, and I will be a real CNC apprentice from now on.

"Do you know why I just taught you programming today?"

"do not know."

Xu Yang pricked up his ears and listened carefully.

Xu Hui expressed satisfaction with Xu Yang's serious attitude towards learning.

So pointing to the engraving machine, he continued:
CNC lathes are also called computer gongs, and ours is a small precision machining CNC machine tool, referred to as "carving machine".

CNC lathe feed processing route refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the processing program, including the path of cutting processing and non-cutting processes such as cutting in and out of the tool. Empty travel path.

The feed route of finishing machining is basically carried out sequentially along the contour of its parts. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and empty stroke.

……

To sum up, the core of the above is programming.

Seeing that Xu Hui had talked a lot, Xu Yang probably felt a little dry, so he hurriedly handed him the water glass.

"Understand?"

Xu Hui smiled knowingly, took a sip of water, and asked.

"Ding! Xu Hui's favorability +5!"

"This... really doesn't exist."

Xu Yang smiled embarrassingly.

Really.

Xu Yang really didn't understand any of these theoretical knowledge.

But...I understand the degree of favorability...hehe.

Xu Hui seemed to have guessed what Xu Yang would say, and laughed evilly and said:

"Ha ha!"

"That's right if you don't understand."

Xu Yang: "..."

Xu Hui, who had just put down the water glass, saw Xu Yang's face, secretly pleased:
"This is how I came here at the beginning, and this tradition must be passed on. Speaking of Xiao Xu...why is he like a primary school student?"

"Silly and cute...haha!"

Xu Hui secretly flirted, and then pretended to be deep and said:
"What I'm going to say next is all hard work, and I'm ready to record a video."

record video?
Xu Yang was taken aback when he heard the words, yes, I can record a video.

Xu Hui continued:
"The teaching mode just now is just the standard teaching mentioned in the book. In fact, CNC is not so complicated."

Let me tell you this, CNC has two points in the eyes of our hardware mold factory:

Programming + operation.

In the first half of the year, I let you operate the machine, in fact, to let you familiarize yourself with the part structure, tool characteristics, and processing paths.

Only if you are familiar with the basic operations of machining can you know how to compile machining programs.

After finishing speaking, Xu Hui glanced at Xu Yang again;
"Did you understand this time?"

Hearing this, Xu Yang said thoughtfully;

"Well, I understand a little bit."

Only now did Xu Yang understand Xu Hui's good intentions. It turned out that the reason for not teaching himself programming in the first half of the year was to lay a solid foundation for better learning of programming.

At this moment, Xu Hui opened the UGNX programming software on the computer.

"Xiao Xu, study hard, watch carefully, and don't ask."

"I'm going to start programming!"

At the same time, the sound of the system sounded.

"Ding! Trigger the task of NPC CNC master Xu Hui: follow Xu Hui's instructions and carefully observe the basic teaching of programming. Rewards for completing the task: money +100! Experience +100! Programming experience +100! Favorability +10! There is a certain chance of dropping programming aids props."

"Ding! Do you accept? Yes? No?"

isn't it?
There are task rewards for learning technology!
However, this programming aid?

Hearing this, Xu Yang put away all his little thoughts and focused on Xu Hui's programming teaching.

"This is a set of test racks from Qianshida Company, which is a relatively simple test fixture."

Xu Hui explained seriously.

"Hmm!" Xu Yang said seriously.

Xu Hui continued:

After getting a part drawing, first analyze the part drawing to determine the processing process, that is, determine the processing method of the part (such as the tool and fixture used, the clamping and positioning method, etc.), the processing route (such as the feed route, tool setting method, etc.) point, tool change point, etc.) and process parameters (such as feed rate, spindle speed, cutting rate and depth of cut, etc.).

(1) Determine the processing route
The processing route is determined according to the principle of rough processing first and then fine processing, and the external shape is rough processed by a fixed cycle command, and then fine processed.

(3) Select tool

According to the processing requirements, the tools for processing bakelite are generally used: four-edged milling cutter, lettering knife... chamfering knife for finishing.

(4) Determine the amount of cutting
Bakelite with a diameter of 10MM can use a speed of 2000 and a feed speed of 3000.

Bakelite with a diameter of 20MM can use a speed of 1200 and a feed speed of 3800.

We are going to sit on this test stand, which uses 10mm black bakelite, so we can use the speed of 2000 and the feed speed of 3000.

……

Half an hour later, Xu Hui compiled a processing program for a test frame.

"Ding! The task of Xu Hui, the NPC carving machine master, is completed: money money +100! Experience +100! Programming experience +100! Favorability +10! Additional auxiliary programming props - super UG programming simulator."

Xu Yang was taken aback for a moment, and suddenly his eyes lit up.

Oh, a lot of harvest.

But this super UG programming simulator?
"Ding! Warm reminder: Super UG programming simulator, this is a special prop specially generated for the host, it can help the host program all the processing parts.

The specific operation is as follows: the host only needs to scan the part drawing with the super UG programming simulator, and the programming can be completed automatically in one second.

Limitations: The difficulty level of NC programming for processing drawings cannot be higher than two levels of the host's professional level, otherwise the simulator will not be able to recognize it. "

"!!!"

Super UG programming simulator.

Isn't this auxiliary programming tool too perverted?
Usually when he sees Xu Hui programming, it is also step by step.

Programming is mental work!

Because you have to master different GM codes, processing paths, props, milling... Then choose the best tool path, and finally complete the processing program.

Now there is a super UG programming simulator, fully automated programming?

quack!

Although he was surprised, Xu Yang still listened carefully and calmly.

"After programming, it's processing!" Xu Hui uploaded the edited program to the Jingdiao machine, and said seriously.

"Pay attention to safety first!"

"Yeah." Xu Yang nodded.

It is necessary to mention here that for technicians engaged in the machinery manufacturing industry, safety always comes first.

There are countless cases of tragedies, such as severed fingers, eyes stabbed by iron filings, and the most terrifying thing is being killed by flying knives. These are not alarmist words, but the real and painful lessons of the predecessors.

"Yes!" Xu Yang agreed.

"I'm about to start!"

Accompanied by Xu Hui's uncharacteristic voice, Xu Yang clearly felt the atmosphere of the teacher's class when he was in school. The aura of seriousness and concentration on learning enveloped him virtually.

Xu Hui inserted the USB flash drive into the computer, and then uploaded it to the Jingdiao machine software, and the next step was processing.

　Rejuvenating the country through industry, CNC technology!
