What Tu Min didn't expect was that Lin Fan, who had been working quietly and quietly, had already finished the game.

The timekeeper came to record the processing hours for the first time.

Immediately afterwards, a quality inspector and a programmer came to inspect the workpieces processed by Lin Fan and the processing procedures.

For the sake of fairness, the invigilators of this competition are all office staff of the Guanzhou Machinery Association. The quality inspection was done by a middle-aged woman in her 40s, and the audit process was carried out by an old man who was close to 60 years old.

As soon as the old man got started, there was a lot of stir around.

Lin Fan stood next to the machine tool, and asked the young man next to him when he was idle, hey, this old man is actually the vice president of the Machinery Association!

At the opening ceremony just now, Lin Fan noticed that this old man had been sitting in the front row of the venue, thinking that he was a leader of no low rank, but he didn't expect that he was actually a vice president!

But how can a vice president be idle and start a programmer?

The young man next to him obviously had Chen Qiang's broken mouth attributes. Before Lin Fan could inquire again, he thoroughly explained the life history of this vice president.

The vice president's name is Liu Binglong, who was also born in machine tools, and later studied for exams on his own while working, and became a programmer in a machinery factory. Then the machinery factory was reformed and reorganized, and the old man was in his 40s and took the exam again to be a clerk of the Listed Machinery Association......

All in all, this Liu Binglong is a living old scholar.

It stands to reason that the procedure should be checked for correctness and error, after all, the workpieces used in the exam are all pre-machined.

But the vice president checked the program, but stood in front of the machine controller for a long time and did not respond.

When the middle-aged woman brought the measurement results, the old man compared them for a long time, and even took out a palm-sized hard-faced notebook from his left trouser pocket, and took notes while looking at the open program.

The young man with a broken mouth has already introduced himself to Lin Fan, his name is Zhao Guangzhong, and he is the secretariat of the association.

Lin Fan didn't know what kind of existence this association secretariat was, but just looking at the smugness in Zhao Guangzhong's eyes when he introduced himself, it should be a very important organization in the association.

But is it really good to let this broken mouth work in a functional department?

It may take a few seconds for a CNC machining program to run, but it is undoubtedly quite a waste of time to manually transcribe it.

Zhao Guangzhong looked at Vice President Liu Binglong's solemn look, but put away a little arrogant. Looking at Lin Fan, who was standing there with a harmless face and quietly waiting for the result, he couldn't figure out what a procedure was worth studying for a long time.

After about five minutes, Liu Binglong finally finished copying the program.

Zhao Guangzhong couldn't hold back the burning gossip in his heart, and stepped forward with a straight face and asked, "President Liu, is there no problem with this master's procedure?"

Liu Binglong was still thinking about his thoughts, but a burst of heat suddenly jumped in his ears, startling him.

"Ahh

came back to his senses and helped his black full-rim glasses, "It's all fine, full marks!"

As soon as Liu Binglong finished speaking, the people around him turned their eyes to Lin Fan, who was playing a good baby.

Zhao Guangzhong was also taken aback. He has been working in the association for several years, and this is not the first time he has participated in the skills competition. This is the first time I've heard of someone getting a perfect score.

You must know that machining, especially CNC machinery, will have many abnormalities in the processing process.

For example, this lathe competition not only requires that the error of the processed workpiece be within a few wires, but also deducts points for even the slightest mistake in the program. For example, setting zero bias, opening and cutting, program pause function, and so on.

If there is enough time for the competition, I believe that the vast majority of participants will end perfectly, after all, those who can sign up for the competition are not beginners. But this is a competition, not actual production, let alone scientific research, so there will always be all kinds of accidents.

After all, human mental power is limited. In just two hours, not to mention that there is no small mistake in the program, even if the program is completely wrong, resulting in a knife, moving, or even dropping the entire workpiece, it can be produced once or twice a year.

But now Liu Binglong, Chairman Liu, actually said full marks?!

What international jokes?!

Zhao Guangzhong looked at Lin Fan, who was still doing nothing, this guy doesn't seem to be as old as me, right?

As soon as Liu Binglong finished speaking, he beckoned to Lin Fan, who was standing next to him: "This master, I have a few questions I want to ask, can you help you explain?"

Lin Fan pointed to the tip of his nose, meaning "call me"?

Liu Binglong nodded, turned around and pointed to the program in the controller and asked, "What I want to ask is, there are a few data in your program that are not quite the same as the requirements in the drawings, please tell me about it." ”

Lin Fan stepped forward and looked at what Liu Binglong said was different.

“……

g03x1200.02z-120.00cr=0.4f0.20

g01x1199.20z-322.00

……”

Liu Binglong continued: "The outer diameter required in our drawings is 1200 mm, why do you write 1200.02 in the program?"

Lin Fan looked at Liu Binglong with a clear look. The heart said that you old man didn't ask knowingly!

There was a scorn in his heart, and he still had to answer honestly: "President Liu, you should know best." The inserts we use in machining are worn. After the above few paragraphs of the program are finished, there is already a slight loss of the knife tip. If I write the program as g03x1200, the final processed data will definitely be less than 1200 ......."

Liu Binglong nodded.

This question is not difficult to understand, but anyone with a little processing experience can think of it. It's just that how he determines the timing of processing to this position

Wait, the wear level of the tip of the knife is exactly 0.01 mm?

Puzzled, Liu Binglong asked directly.

"I don't know about that. Lin Fan spread his hands and said innocently, "Guess." ”

Zhao Guangzhong looked at Lin Fan's appearance of being a hanger, and the first one couldn't bear it, and said unhappily: "What's the matter with your master, is the machining based on guessing?!"

Lin Fan usually has never had a good impression of this kind of broken mouth. I didn't provoke him, but I didn't expect him to come over to find Baba's stubble first.

As soon as his eyebrows were raised, Lin Fanlie was about to scold this kid.

At this time, Liu Binglong waved his hand at Zhao Guangzhong and said, "Xiao Zhao, pay attention to what you say." Although this master does not look very old, he must be an old worker with rich processing experience. Of course, this master said that the guess is not right, to be precise, it should be experience. I'm right, Lin ...... Master Lin?"

Wonderful!
