Seeing this, Xu Zhenming raised his head, retracted his gaze, gave Zhang Lin a look, and signaled him to immediately start the computer board of the clothing computer model cutting machine.

The control program of this garment computer model cutting machine is still a modified version of the CNC system of the CNC machine tool.In other words, Xu Zhenming has developed a CNC system that can be applied to all the intelligent equipment currently produced by Yiming.

Yiming company currently produces CNC flame cutting machine, CNC machine tool transformation, computer engraving machine prototype, computer cutting machine prototype, clothing computer prototype cutting machine and computer embroidery machine, etc.The control principle of all intelligent equipment is the same, except that some changes have been made when applied in the industry.

This is the so-called product chain diffraction or horizontal expansion of the industrial chain. It is very simple in the eyes of skilled technical engineers, and very mysterious and unfathomable in the eyes of laymen!

"Mr. Xu, the self-check of the clothing computer model cutting machine is normal! The cutting blade has been installed, and you can send the layout of the clothing model!"

At this time, Zhang Lin checked again and smiled and reported to Xu Zhenming.

In general, he was very careful in doing things. Checking the blades, adjusting the machine head, setting the coordinate zero point... etc. were all carried out in accordance with the operating procedures.

The blade of this clothing computer model cutting machine is a small blade that is folded off from the art blade, mainly for the convenience of customers to buy blades for consumable parts.

Whether a piece of equipment is well designed or not, consumables are very important!

When Xu Zhenming designed this clothing computer model cutting machine, he designed the cutting head knife into the most common art blade to make it easier for customers to buy knives. He was not prepared to make money from customers and pit customers in the knives!

"Manager Zhang, do you want to observe whether the rotation of the cutter bar of the nose is synchronized?"

Taking a look at Zhang Lin next to the clothing computer model cutting machine, Xu Zhenming pressed the send button on the laptop.

After a while, the layout of the clothing pattern in the laptop has been transferred to the computer board of the clothing computer pattern cutting machine.The clothing computer model cutting machine is driven by a servo motor, first moves at a high speed, and then decelerates to the position of the cutting starting point, ready to start cutting.

For this kind of acceleration and deceleration, only the synchronous servo motor can embody the algorithm code of the CNC control system program, and the stepper motor cannot achieve this effect.

"Mr. Xu, the cutting is normal, and the movement is synchronized with the movement of the X-axis and Y-axis!" At this time, Zhang Lin was reporting the results while observing.

After the machine head dropped the knife, it began to move in a straight line, and the direction of the knife was normal, and the kraft paper was easily cut.The cut is smooth and has no burrs; the lines are smooth and there is no fine jagged.

This phenomenon shows that: the X-axis and Y-axis directions of this garment computer model cutting machine have high mechanical performance accuracy, smooth movement, and no vibration.

"Okay! This time it will definitely be successful!"

Seeing this situation, the technicians participating in the assembly and debugging applauded.

In order to get out the testing machine of the clothing computer model cutting machine as soon as possible, they have been working overtime these days, desperately rushing to the deadline day and night.Now if the equipment can be successfully debugged once, people like them are naturally more happy.

Xu Zhenming and Zhang Lin are also in a good mood.

however.At this moment, a "pop" came from under the knife of the machine head, and the blade that was cutting the arc was broken!

Seeing this situation, Zhang Lin's first reaction was to shout: "Mr. Xu! The CNC control system program of the clothing computer model cutting machine is not synchronized, and the turning of the tool is not synchronized with the X-axis and Y-axis!"

While talking, he pressed the pause button on the control panel of the clothing computer model cutting machine to terminate the operation of the cutting instructions in the computer board, and the clothing computer model cutting machine also stopped.

Xu Zhenming's reaction was exactly the opposite of Zhang Lin's reaction, and he smiled slightly: "Manager Zhang, you arrange for a man to check the steering system of the machine head tool immediately! It should be a mechanical problem with the tool system!"

The core code of the CNC control system developed by Xu Zhenming has been tested by countless CNC machine tools, and no similar problems have occurred.This time, he thinks it will be no exception.

Problems like this clothing computer model cutting machine often appear in four-axis CNC machine tools.The problem of the fourth axis out of synchronization is almost all caused by mechanical failure.It is precisely because of the machining accuracy of mechanical parts that the research and development of domestic CNC machine tools lags behind.

"Let me see!"

Hearing what Xu Zhenming said, Zhang Lin whispered and turned off the power supply of the clothing computer model cutting machine.He knew that his boss Xu Zhenming would not be aimless. Although he was still shaking his head, he had already picked up the screwdriver to remove the cover of the nose.

This machine head was assembled and debugged personally by him. How could mechanical failure occur?

He was very puzzled!

After dismantling the head cover, Zhang Lin first carefully observed the appearance of the movement mechanism of the cutter system.Everything was normal and no abnormalities were found.

At this time, Xu Zhenming had already opened the emulator synthesis software he had written, and called up the running situation of the program code just now.From the point of view of the synchronization of the program code: the CNC control system of the garment computer model cutting machine is normal, which is consistent with his guess.

After reading the program tracking code, he raised his eyes and looked at Zhang Lin, and said, "Manager Zhang! You turn the tool bar of the tool system!"

"Oh!"

Zhang Lin responded, pinching the knife shaft with his right hand and turning it.

He is not very experienced in debugging four-axis linkage machine tools, so he can only follow Xu Zhenming's instructions."Huh! How could the knife shaft turn? Isn't it locked?" He yelled in surprise immediately.

The servo motor has a feature, it will lock up when there is no signal, and the spindle will not rotate a bit.The tool bar of the tool system is connected through a gear set and a steering servo motor.When this happens, either the servo motor is malfunctioning or the gear set is malfunctioning.

"It should be because the gear set does not bite, there is a gap!"

"Maybe the spindle of the servo motor is broken!"

"Just take it apart and take a look! I'll help!"

After seeing this situation, Zhang Lin's technicians all started talking.

Up to now, they all know that their little boss has rich experience, in a word, the cause of the problem has been locked: the problem of the tool turning out of synchronization is that the mechanical failure has nothing to do with the CNC control system program.

Everyone stepped forward to help, all hands-on, and after a while, they unloaded the head of the clothing computer model cutting machine.Everyone started to work separately, someone was responsible for checking the servo motor; someone was responsible for checking the gear of the servo motor shaft head; someone was responsible for checking the gear of the tool system.

"Report to Mr. Xu: Everything is normal for the servo motor, and it is in a locked state after power off!"

"Report to Mr. Xu: The gear on the shaft end of the servo motor is also normal!"

"The gear matched with the servo motor is fine!"

Not long after, the technicians reported the results of the inspection to Xu Zhenming and found no abnormalities.

It's really weird!Separate inspection of mechanical parts is fine, but there is a problem when assembled together!

This situation often occurs in domestic machinery and equipment, and it is not only the Yiming company.This is the problem of machining accuracy, Xu Zhenming has experienced many times.

Zhang Lin and the others understood too well, so they had to look at their little boss Xu Zhenming, wanting to get an accurate answer!

"Let's do it! You assemble the gear set on the tooling and test it once to see how the bite is?" After seeing the helpless expressions of everyone, Xu Zhenming smiled and commanded.

This problem is very common for him, there is no fuss.

Everyone got busy when they heard the words and disassembled the gear set on the nose and reinstalled it on the test tooling on the workbench.Not long after, a gear set has been installed on the gear set inspection device that simulates the steering of the tool system.

The technicians under Zhang Lin turned the gear set according to mechanical principles.Running to a certain angle, this gear set suddenly appeared a big gap, but it swayed back and forth, exactly the same as the problem found on the nose.

"Who processed this gear set? It's a pitfall!"

"It has nothing to do with processing!"

"What does it have to do with?"

The technicians under Zhang Lin were very angry at this moment, blushing and yelling.

The experienced old fitters have experienced this situation, but they can't tell the reason; the young technicians have not seen this situation, and they are naturally more emotional.

Seeing this situation, Xu Zhenming smiled and told everyone of his experience: "This is the performance after the mechanical error is superimposed! Especially the transmission method of the gear set! So, you immediately replace a set of gear sets, do the test first. Assemble it on the nose!"

He didn't hide it, and passed on his accumulated experience to everyone.

Through this incident, Zhang Lin decided to add an assembly and debugging process for the gear set of the tool system; the technicians knew about the transmission of the gear set.In short, everyone has benefited a lot!

Soon, a new set of gear set was successfully debugged and installed again on the head of the garment computer model cutting machine.

This time, Xu Zhenming changed his debugging method.

He wrote a small program on the spot to test the problem of unloaded tool turning.Since the cover of the machine head is not installed, everyone can see clearly how the tool system is turned.

"The turning of the tool system is very complicated! Once there is a small problem in the machine, the head of the cutting blade will be broken!"

"This shows that the garment computer model cutting machine we developed is very advanced!"

"With such advanced technology, I guess no domestic manufacturer can imitate it!"

The technicians saw this scene, while recording the parameters, while talking in a low voice.

In a short while, the experiment of the tool system of the head of the garment computer cutting machine is completed, and the whole machine can be debugged and tested immediately.

Seeing this situation, Zhang Lin arranged for his technicians to restore the nose to the original state, waiting for Xu Zhenming to give instructions for the test.
