Chapter 225: Nanoscale calibration (below)

No one will reject Guo Tailai's reasonable request. In fact, even the vice president of Mercedes-Benz only wants to establish cooperation first, but specific cooperation conditions require further negotiations.
Guo Tailai made it very fast, at least in the eyes of the Mercedes-Benz engineers, the speed of manufacturing the workpiece was amazing.
No way, Guo Tailai is handmade, as long as the drawings are optimistic, you can get started. Unlike CNC machining centers, even if you enter a drawing, what kind of process is required, and what kind of operation is required, further settings are required. It takes a long time to set this up.
Although the efficiency of large-scale machining of fully automatic CNC machining centers is amazing, in fact, if you are not sure about the process and only input the drawings, the machining center may not even have a knife. Even simple drawings can be used to automate the process, but complex accessories require manual intervention.
This is one of the reasons why some manufacturers have good equipment, but they are not necessarily able to process high quality workpieces quickly and well. The operator's inexperience in these settings, or setting errors, are all influencing factors. For example, it is obvious that you can take a knife of ten millimeters at a time, but the operator is afraid of damaging the machine, so if you set a five millimeter, you have to take two knives, and the time efficiency will naturally decrease. when
However, with the development of technology, according to the setting of the workpiece material and the machining center, it is also possible to intelligently give the parameters of the maximum amount of movement. Similar processing steps can be intelligently set. Unfortunately, that is the future, and it is still far away. That's it.
Therefore, in the processing of one or two pieces of workpiece, even with the most advanced CNC machining center, the processing speed may not be comparable to that of Guo Tailai. The efficiency of a single individual is far worse than that of Guo Tailai. eye
Looking at the titanium alloy parts from the dust-free work room, the engineers of Mercedes-Benz are very upset, and can't wait to see Guo Tailai's side to see how Guo Tailai is processing this difficult-to-machine alloy. It is a pity that Huang Weiguo and the three of them are very responsible to keep at the door. No one can go half a step.
Although many people know that Guo Tailai is actually grinding with hand tools a little bit, but why can Guo Tailai achieve this precision? It’s always a mystery that people can’t explain. Is it a bit too exaggerated to cut titanium by hand? How much power does that need? How much endurance is needed? Guo Tailai obviously has no obligation to explain, but he has quickly produced one by one. Do not
Engineers who are very curious soon know how much strength and endurance they need. When Guo Tailai took two sets of worn out tools and asked for replacement, it was already ten hours after he worked continuously.
In ten hours, Guo Tailai had been working at other times besides eating a meal, and even drinking water did not delay the work, it was unbelievable.
Fortunately, Mercedes-Benz has long anticipated this situation, and quickly replaced two sets of tools. These tools are so badly worn, especially for the final polished part, even the sand surface above is almost bald. The edge of the cutting blade is so bad that it can't be changed.
For three days, Guo Tailai completely completed the construction of all titanium alloy parts. This has already surprised the engineers on the Mercedes-Benz side, and it is a titanium alloy! Still so high precision. Don’t look at the former Soviet Union’s use of titanium alloys to play airplanes and play submarines. Let them take the precision of processing. Guo Tailai can easily kill a link that they don't know how many streets. work
The laboratories have already contacted them, only waiting for Guo Tailai to take them with them. What people in Mercedes-Benz do not understand is that if Guo Tailai just wants to know how high-precision the workpieces he has made, he doesn’t have to go over it himself, let the measurement there send the results, but Guo Tailai wants to stare at the past. Look.
Maybe it is the quirk of the craftsman! If you look at the measurement yourself, you will know what you are doing. Anyway, the person in the lab is working on the measuring instrument. Guo Tailai only looks at a reading. It will not cause any leaks in the production process. The Germans showed the greatest tolerance in the small demands of a master craftsman. each
A workpiece to be measured, Mercedes-Benz is wrapped with the best soft film material, and then placed in the gap of the appropriate position of the shock-proof material, and then installed in several security boxes. It can guarantee that collision damage will not occur due to bumps during the road trip. car
All the way to the south, heading to Munich. The industrial laboratory is in Munich, and the headquarters of BMW is also there. Guo Tailai on the road also joked with the people of Mercedes-Benz and McLaren, maybe the next time to be a monster motorcycle, can not cooperate with BMW. Ben
Chi and McLaren currently have no motorcycle business. Guo Tai said this, but it did not cause resentment between the two sides. Mercedes-Benz managers even laughed and could help introduce the business manager of BMW Motorcycle. in
In the industrial laboratory, Guo Tailai first saw the world's most accurate measuring instrument, a model of laser interferometer. A laser interferometer is an instrument that measures the length to be measured using wavelength as a standard. By interfering with the magnified pattern to read out the data, it can be accurate to the nanometer level. Guo
Tailai was very disciplined and sat on the opposite side of the laser interferometer three meters, watching the laboratory staff operate the interferometer for measurement. "
Calibrate the 360-degree field of view 3d measurement mechanism. ""
To start calibration, please specify a reference.

......
With each reading read and recorded, Guo Tailai's 360-degree field of view 3D measurement is also in constant calibration. This measurement and calibration lasted for one and a half days before the size of the workpieces that Guo Tailai was to measure. The measurement was completed, and Guo Tailai's measurement mechanism was completely calibrated after one day.
The measurement mechanism of the 360-degree field of view has been accurate to 5 nm, which is 0.005 μm. The Pentium 3 processor, which went on sale in January this year, uses a 0.25-micron process technology, which is 250 nanometers. It is conceivable that this is a high measurement accuracy. "
The nano-robot cutting accuracy is enhanced to 50 nanometers. ""
The nano-robot welding accuracy is enhanced to 50 nm. ""
The nano-robot surface roughness is strengthened to less than 5 nanometers.

The three consecutive reminders made Guo Tailai completely happy. All the enhancements brought by the last system upgrade have been activated. Now Guo Tailai's processing accuracy can reach 50 nanometers, which is 0.05 micron.
