Chapter 13: Measurement and calibration

The process of withdrawing money was carried out under the murderous eyes of Zhao Wei. After receiving the money, Guo Tailai took another 30,000 to remit money to the family and called Guo Jianjun to explain that this was the second payment of the patent transfer, all accompanied by Zhao Wei.
"Follow me to the lab!" Wait until Guo Tailai has done all this, Zhao Wei ordered.

What?
Guo Tailai’s reflective guilty question:
You don’t have titanium alloy now, don’t you worry so much?


Don't you say that you can measure the size by visual inspection?
Zhao Wei’s sinister threat:
Now give me the lab, I have to see how accurate you can visually.

Don't look at what Zhao said is so fierce, but she has some faith in her heart. Of course, I don't believe in anything like white beard and qigong. I believe that Guo Tailai's myopia is restored and visually sized. Liu Lao and her once said that when the fat man did the crankshaft, he did not move a measurement tool.
5 micron processing accuracy, no measurement instrument at a time, this is really a bit of a fantasy. Therefore, Zhao Wei found the opportunity and definitely had to verify it personally.
Into the 9003 building, this time Zhao Wei did not take Guo Tai to go to the inertial laboratory, but went straight to the cims (CNC machine) laboratory, where the most sophisticated measurement tools.
Among the knowledge that Guo Tailai has learned so far, the dial gauge is the most sophisticated tool. It is only in the laboratory that it is known and more sophisticated.
Germany asimeto rectangular block gauge, 0 level accuracy, the full block gauge is stored in the thermostat measuring room at 20 degrees Celsius, this is the measurement artifact that can really be accurate to 1 micron, but unfortunately, the use can only be carried out in a constant temperature environment.
Before Guo Tailai used only the dial gauge calibration. When he listened to Zhao Wei's introduction and knew that this was the real precision measurement tool, he was overjoyed. According to the above scale, he stared at each block gauge and started in his mind. give command.

Calibrate the binocular 3d measurement mechanism.


Start calibration, please specify a reference.

......
Every time I watched a piece, Guo Tailai calibrated a piece of size. Each piece of Guo Tailai looked carefully for at least a minute. The whole time went down and it took more than an hour.
However, this also makes Guo Tailai's binocular measurement accuracy really reach 1 micron, before the dial gauge is also 1 micron, but did not take into account the temperature effect of the dial gauge itself, although the accuracy scale is high, but there is still a certain error. After the block gauge is recalibrated, it can be said that the last error has disappeared. The true 1 micron is 1 micron.
Zhao Wei is very patient and waiting for Guo Tailai. Of course, she is not waiting for it, but is initiating another measurement tool.
The laser is longer than the long gauge. It also needs to be thermostated at 20 degrees. It is an instrument that can accurately measure the length of the super-negative 0.2 0.2 micron / 1000 mm. The measurement and reading can only be performed by the microscope. At present, the most accurate measuring instrument in China is this one.
If the blade was not taken away, it was sent here for measurement, but it was now used by Zhao Wei as a tool to test Guo Tailai's visual ability.
"And this kind of artifact? Let me see what this precision is," Guo Tailai listened to Zhao Wei's introduction, almost rushed to hold the laser than the long instrument to calibrate, finally know that this high-precision instrument can not have a little bit Vibration interference, this is tolerant, but still let Zhao Wei operate again, let yourself see how to measure.
Zhao Wei did not deny it. He took a piece of gauge with a glove and placed it on the laser to measure the result. After the result was obtained, Guo Tailai observed the result from the reading microscope. In addition to the block gauges, there are also some rules for measuring the samples, which are also measured to a precision of 0.2 microns.

Calibrate the binocular 3d measurement mechanism.

......
After another operation, Guo Tailai's eyes were calibrated by the laser length meter, and the measurement accuracy was improved again. It has reached the abnormal level of 0.2 micron accuracy, and is the most scientific and accurate 0.2 micron.
With this precision, it is basically meaningless in the macro processing industry, because as long as it is a little bit of disturbance, it may be that a breath may affect the dimensional change of the measurement target.
Now Guo Tailai's mind shows the measurement results of some targets, and the decimal point has been changing since the third place.
After calibration, Guo Tailai can basically use no measuring tools in the processing field. His eyes are more accurate than any tool on the market.
"Well, let's take a test!" Guo Tailai was satisfied. In the face of Zhao's suspicion, it was very confident that Zhao Wei would make a problem.
Zhao Wei is not at all polite, the block gauge keeps changing the combination, and then let Guo Tai come to see it.
Guo Tailai also has no Tibetan mastiffs. In order to let Zhao Wei completely die, every time he said that the accuracy is extremely accurate, even to 0.2 micron, and the laser is one level.
Sometimes it is not the integer that just adds up. The laser is better than the long one. Guo Tailai actually said that the score is not bad, it is simply unbelievable.
"Are you a monster?" Zhao Wei has been in the test for hundreds of times. In addition to the block gauge, he immediately found something to measure. Guo Tailai always can accurately say the size, so that Zhao Wei can no longer dare Believe in your own eyes.
"Obviously not!" Guo Fatzi was in a good mood today. He did not say 100,000 yuan. He also really calibrated his visual accuracy. Everything happened to be a piece. The whole process was a smile. At this moment, the answer is also a smile. .
Although the fat man is fat, but he is very happy, this smile is a very affective face. Zhao Yu was amazed and looked at the fat face of the fat man. For a moment, he felt that the fat man was pleasing to the eye.
When leaving the cims lab, Zhao Wei was still unbelievable. The performance of the fat man almost subverted Zhao's cognition. Even after so few moments, Zhao Wei couldn't help but believe that Guo Tai's white beard grandfather's qigong was said. Otherwise, how can normal humans be so abnormal?
"Please use this evaluation on your own." Zhao Wei said the last sentence directly to Guo Tailai. Guo Tailai was not angry but listened to his own way. I gave it to Zhao Wei: "It is used by a doctoral student who is one year younger than me but who is about to graduate in the spring."
"Well, if you say this, it will make me more acceptable." Zhao Wei took the concept to himself and immediately felt that he could understand. The student of Shuimu University, who has not yet had the ability to do it?
Zhao Wei’s own learning is enchanting, so Guo Fat’s ability in visual inspection and processing ability is normal.
"Don't you say that the paper was completed before the National Day?" The visual test failed to make it difficult for the fat man. When Zhao Wei separated, he once again threatened Guo Tailai: "If you don't finish it, do my sparring."
