Chapter 26 Measurement Calibration (Part 2)

The process of withdrawing the money was carried out under Zhao Yanyan's ferocious eyes, including after receiving the money, Guo Tailai withdrew another 30,000 yuan to remit to his family, and called Guo Jianjun to explain that this was the second payment for the patent transfer, all accompanied by Zhao Yanyan.

"Follow me to the laboratory!" Zhao Yanyan ordered after Guo Tailai finished all this.

"What are you doing?" Guo Tailai asked reflexively, "You don't have titanium alloy now, so don't be so anxious?"

"Didn't you say that you can measure the size by visual inspection?" Zhao Yanyan threatened viciously: "Go to the laboratory now, and I want to see how accurate your visual inspection is."

Although what Zhao Yanyan said was so fierce, deep down in her heart she already believed it. Of course, I don't believe in the qigong of the white-bearded old man, but in Guo Tailai's myopia recovery and visual measurement. Mrs. Liu told her once that day that Fatty didn't move the measuring tool once when he was making the crankshaft.

The processing accuracy of 5 microns does not require a measuring instrument once, which is really a fantasy. So Zhao Yanyan found an opportunity, and definitely had to verify it himself.

After entering the 9003 building, Zhao Yanyan did not take Guo Tailai to the inertial navigation laboratory this time, but went straight to the CIMS (CNC machine tool) laboratory, where the most precise measuring tools can be found.

Among the knowledge Guo Tailai has learned so far, the dial indicator is the most precise tool, but he didn't know until he arrived in the laboratory that there are more precise tools.

German ASIMETO rectangular block gauge, 0-level precision, a full set of block gauges are stored in a constant temperature measurement room at 20 degrees Celsius, this is the real measurement artifact that can be accurate to 1 micron, unfortunately, it can only be used in a constant temperature environment.

Guo Tailai had only used a dial gauge to calibrate before. When he heard Zhao Yanyan’s introduction and knew that this was the real precise measuring tool, he was overjoyed for a moment. He stared at each gauge according to the scale above, and began to think about it. Give instructions.

"Calibrated binocular 3D measurement mechanism."

"Start calibration, please specify reference object."

...

Guo Tailai calibrated the size of each piece every time he looked at it. Guo Tailai looked at each piece carefully for at least a minute, and it took more than an hour to finish the whole piece.

However, this also allowed Guo Tailai's binocular measurement accuracy to reach 1 micron. The previous dial gauge was also 1 micron, but the temperature influence of the dial gauge itself was not considered. Although the accuracy scale is high, there is still a certain error. After recalibrating the block gauge, it can be said that the last error has disappeared, and the real 1 micron is 1 micron.

Zhao Yanyan waited patiently for Guo Tailai. Of course, she was not just waiting, but was initializing another measurement tool.

The laser ratio meter, which is more powerful, also requires a constant temperature of 20 degrees. It is an ultra-powerful length measuring instrument that can be accurate to plus or minus 0.2 microns/1000 mm. Measurements and readings can only be carried out through microscopes. It can be said that , at present, the most accurate measuring instrument in China is this one.

If the leaf hadn't been taken away, it would have been sent here for measurement, but now it is used by Zhao Yanyan as a tool to test Guo Tailai's visual inspection ability.

"Is there such a magic weapon? Let me see what this precision is like." After hearing Zhao Yanyan's introduction, Guo Tailai almost pounced on him to calibrate it with a laser measuring instrument. He finally knew that this kind of high-precision instrument cannot be accurate Only then did Zhao Yanyan hold back the vibration interference, but let Zhao Yanyan operate it again so that he could see how to measure it.

Zhao Yanyan did not refuse, and took a piece of gauge with gloves on, and put it on the laser ratio meter for measurement. After getting the result, he asked Guo Tailai to observe the result on the reading microscope. In addition to block gauges, there are also some regularly measured samples, which are all measured to 0.2 micron precision.

"Calibrated binocular 3D measurement mechanism."

"Start calibration, please specify reference object."

...

After another operation, Guo Tailai's eyes have been calibrated by the laser ratio meter, and the measurement accuracy has been improved again. It has reached the abnormal level of 0.2 microns, and it is the most scientific and accurate 0.2 microns.

At this level of accuracy, it is basically meaningless in the macro-processing industry to go further, because as long as there is a slight disturbance, it is possible that one breath may affect the size change of the measurement target.

Now Guo Tailai's mind displays the measurement results of some targets, and the decimal point has been changing since the third place.

After calibration, Guo Tailai can basically no longer use any measuring tools in the processing field. His eyes are more accurate than any tools on the market.

"Okay, let's take the test!" Guo Tailai was satisfied. Facing Zhao Yanyan's doubts, he asked Zhao Yanyan to write the test with confidence.

Zhao Yanyan was not polite at all, he kept changing the combination of blocks, and then asked Guo Tai to visually observe.

Guo Tailai didn't hide his clumsiness either. In order to make Zhao Yanyan completely give up, every time he said it was extremely accurate, even accurate to 0.2 microns, which was on the same level as a laser ratio meter.

Sometimes what is said is not an exact integer, and Guo Tailai actually said exactly the exact number when tested with a laser ratio meter, which is unbelievable.

"Are you a monster?" Zhao Yanyan went through no less than hundreds of tests, besides the block gauge, he also found some things to measure. Guo Tailai was always able to tell the size with incomparable accuracy, so that Zhao Yanyan never dared to Trust your eyes.

"Obviously not!" Fatty Guo was in a good mood today. Not only did he receive 100,000 yuan, but he also calibrated his visual accuracy. All the good things came together, and he was smiling the whole time. He answered the same thing at this moment, with a smile on his face .

Although the fat man is fat, he looks festive, and when he smiles, he has a very friendly face. Surprised, Zhao Yanyan looked at Fatty's festive face, and suddenly felt that Fatty was much more pleasing to the eye.

When leaving the CIMS laboratory, Zhao Yanyan still had a look of disbelief. The fat man's performance almost overturned Zhao Yanyan's cognition, and even for a few moments, Zhao Yanyan couldn't help but want to believe Guo Tailai's statement about the qigong taught by the white-bearded grandfather, otherwise how can normal human beings be so perverted?

"Please use this evaluation on yourself." Zhao Yanyan told Guo Tailai the last evaluation directly. It was given to Zhao Yanyan: "Use it on the doctoral student sister who is one year younger than me but is about to graduate in the spring."

"Well, what you said made me more acceptable." Zhao Yanyan applied the concept to herself, and immediately felt that she could understand it. Who among the students of Shuimu University hasn't learned how to be human?

Zhao Yanyan himself is a monster in studies, so Fatty Guo's ability in visual inspection and processing is also normal.

"Didn't you say that the thesis should be finished before the National Day?" Visually, Zhao Yanyan failed to make things difficult for Fatty. When Zhao Yanyan left, he once again threatened Guo Tailai viciously: "If you don't finish it by then, you can be my training partner."
