Chapter 3 Crashing into a plane should also be a good one

Don't look at Gu Fei's straightforward appearance in the office of the production department on the first floor, but when he stood in front of the machine in front of him, he was at a loss.

He is indeed a student of the mechanical department, and his grades are indeed very good. It's just that the university curriculum focuses on theory, and there are very few places where CNC machine tools are mentioned above, let alone how to operate them.

Many daily products, such as some mobile phones, are directly sold with precision CNC manufacturing as gimmicks. It's just that these selling points and gimmicks can't be looked at directly in the eyes of people in the CNC industry, but it's no problem to trick ordinary people into letting them pay their wallets.

What is the so-called CNC technology or CNC manufacturing?

The officials don't have to be confused on Du Niang, in fact, it is very simple, it is the process of mathematically coordinating each point on the surface of the product, and the machine tool controls the tool to accurately process to the coordinate position.

As for how to make the tool machined accurately, that's a matter for programming and mechanics.

Gu Fei already intended to develop in this area, so he had learned some relevant knowledge before, and after studying it for a while, he began to get on the plane.

He is not too ambitious, and he never thought of making the parts on the entire drawing at once, and only selected the first small part for programming and manufacturing.

In fact, when machining, no matter how complex the parts are, they are also manufactured from small to large, section by section, layer by layer.

Gu Fei began to ponder programming.

For ordinary people, it seems a bit whimsical to think about programming when they first come into contact with CNC machine tools, but in fact, it is not.

CNC lathes are a little more advanced than ordinary lathes, but the advanced ones are not far away, and the programming is relatively simple. Almost all of the technicians don't use computers, and they can make it up by hand.

Gu Fei has solid theoretical knowledge, and the machine in front of him is his own, so he doesn't have to worry about it being damaged, so he can toss it boldly at the moment.

The first section of the part is a cylinder with a length of 20 and a diameter of 10.

Gu Fei groaned for a while, and under the guidance of No. 1, he stood in front of the control panel and started to move.

G0G90G17G40G49

T1M6

G0G90G54X10Z2S......

When the book is used, there is little hatred, and soon Gu Fei can't make it up. Because he didn't know the machining parameters, he didn't know what the spindle speed should be, and he didn't know what the feed speed of the tool should be.

However, there was a number one, so Gu Fei asked directly.

Number one is a real system, let him try it for himself first.

Anyway, it can't be broken, will Gu Fei be afraid of this?

He pursed his lips and went straight to making it up.

I don't know the speed, so let's just come to a good number, give 80,000 rpm per minute. I don't understand the feed, so I just give 5000.

…… S80000M3

G1Z-10. F5000

G0X20.

Z100.

M5

M30

It's just a cylinder, it's simple. Soon, Gu Fei stumbled into the M30 that represented the end of the program.

He picked up the bar stock that had been prepared by the No. 1 next to him, put it into the spindle and locked it, and carefully checked the program. Close the machine compartment door, press it happily, and start.

As a result, there was no result.

The machine was very faceless and did not respond at all.

Gu Fei was surprised and pressed the start again, but there was still no response. He looked up at the monitor blankly, and immediately gave himself a mouthful.

The rotational speed is too high.

The maximum speed of this machine tool is only 8000, Gu Fei gave him 80000, of course it can't run.

Change.

Gu Fei happily deleted a "0" from the speed and started it again.

Brush......

This time it finally sounded.

The machine tossed and turned.

But before Gu Fei could understand what was going on, he heard a chaotic sound in the machine tool, followed by a loud bang, as if he had hit something.

The sound was so loud that even Gu Fei, who was standing on the side, felt the floor jump heavily.

At the same time, the red light erected high above the machine began to flicker wildly. Accompanied by an extremely sharp and piercing alarm, it also began to scream.

Crashed!

Gu Fei's face changed drastically, and only then did he understand what was happening. He hurriedly snapped and slammed the emergency stop button before jumping away with agility.

He waited on the side in horror for a long time, until the alarm was about to deafen his ears, and Gu Fei dared to move over to see what was going on.

Although CNC lathes are relatively safe, as long as they are machines, they will eat people. In the manufacturing workshop outside, Gu Fei met Zhao Wuliang, the supervisor of the stamping department. He didn't pay attention to his work, and his entire hand was wiped out by the machine, leaving only his bare arms, which looked extremely disgusting.

Although this was a laboratory, without asking No. 1, Gu Fei really didn't have the courage to experiment with his body, so he had to be careful.

The emergency stop was pressed, and the machine was theoretically dead. But Gu Fei still cautiously opened the warehouse door, and frowned when he saw him.

I saw that the knife holder of the machine collided directly with the spindle. Is the power of the machine in vain? The material he had just loaded into it did not know whether it was twisted and smashed or knocked away, and it was long gone, and I don't know where it flew.

Under the guidance of No. 1, Gu Fei shut down and restarted. The CNC system is actually a kind of computer, sometimes stuck, restarting it will have unexpected effects.

Pull up the emergency stop, lift the overtravel, and shake the handwheel to move the tool holder out.

After all, CNC machine tools are iron lumps, and the process in all aspects has long been mature, and collisions are almost inevitable in the production process for a long time. As Wu Gong said, you can break it by just messing around, that's just alarmism. In fact, it is just a few more hits, not to mention bad, but it can't even affect the tiny accuracy.

Gu Fei reprogrammed, he didn't move the head and tail, only changed the middle line.

G1Z-1000. F5000

Closing the warehouse door, Gu Fei was shocked and pressed to start.

Sure enough, after a loud bang and a violent vibration, the machine began to scream and alarm again.

That's right, Gu Fei made up the crash program.

Since you have decided to go in this line, you have to learn to get used to it, even if it is a collision.

Not only did he not run away, but he even put his hand on the door of the warehouse, feeling the unparalleled impact of the collision.

I have to say that the decimal car in front of me is not bad, and the power of the collision is not great. If it is a slightly larger machine tool, such as gantry milling, and you dare to stand on the edge of the machine knowing that it will collide, it is really a heartbeat of the extreme memory.

It's like driving a car with a speed of 120 per hour, unfortunately encountering a rear-end collision in front of the front, and having to brake sharply in front of a 50-ton truck. Born in a cold sweat, it's nothing, and he's already a man if he doesn't directly scare the pee.

Shut down, restart, remove the turret and continue.

After going back and forth a few times, Gu Fei's heart was strong enough. When he hit the plane again, he was standing next to him, but his face didn't change.

Number One couldn't help it. Gu Fei was very happy when he collided with the plane, and he was extremely unhappy to hear it, so he had to give instructions in a voice.

"Time waits for no one, you hurry up. Change the program back first, and then pair the knife. Didn't cut the knife you hairy machine. ”

After speaking, the video was automatically unfolded in the hall, and the above content was the method of knife setting for counting cars.

Knife pairs?

Gu Fei slapped his forehead.

Yes, if you don't have the right tool, you dare to open the machine tool, and this is no one.

Because CNC tools are different, large and small, long and short, it can be replaced at any time, but it is not ready to be used.

After all, a machine is just a machine, and it can only move according to various pre-set parameters. These parameters include tool parameters, which are also commonly referred to as tool length compensation.

The so-called tool setting is the method of determining the parameters of the tool.

The tool setting of several cars is the same as that of ordinary lathes, which is very simple. The video in front of him was clear, the explanation was detailed, and Gu Fei's intelligence was normal, so he quickly figured out the process and happily reloaded the knife against the knife.
