How to verify the system is normal? Wouldn't you know how to make a work piece?
Guo Tailai saw an interesting processing process in his dream. A five-axis processing center was used to make a metal basket with a basket and a net. The finished product looked quite realistic.
However, the most impressive thing was the processing process. processing center had changed the angle of the knife and even the parts that were connected to the basket were processed very meticulously. Guo Tai Lai brought this thought up with the Professor Wang before the assembly. The Professor Wang seemed to be very interested and gave Second Brother a mission to finish the processing of the basketball net in advance.
Now that the processing center already had an entire piece of metal, for safety's sake, they did not directly use the titanium alloy, but instead used ordinary steel. They only needed to wait for the console to start the processing process, and that would be enough.
Professor Wang nodded towards Second Brother. Second Brother took another deep breath and imported the processing program of the metal basketball net from the floppy disk. The interface immediately displayed a 3D image of the basketball net.When the academicians and professors, who knew how to handle the process, saw this, they revealed an expression of interest. Such a complex finished product, it must have taken many aspects into consideration, processing only one artifact, one could basically see the performance of this processing center.
With the press of the processing button, processing center's processing shaft began to move very quickly, and the stage also began to rotate. A milling cutter was automatically selected from the cutter plate and fixed in front of the machining shaft. It quickly began to move.
He then saw the outer ring of the metal block being milled into a cylinder. He then changed his knife and continued working on it. A series of movements was extremely smooth and precise. Other people saw the precise cutting of the blade, but in Guo Tailai's eyes, the error of repositioning after changing the blade was not more than 0.1 μm.
What did this mean? Guo knew very well that as long as he could maintain such accuracy throughout the process, the final product would have the accuracy of 0.1 μm. This level of precision, even in the world, was considered the highest level of precision.
The high precision lathe that Guo Tai made last time had a trace of iron filings on its blade. Right now, this processing center with super high accuracy could at least produce 80 or 90 cuts with just a sliver. The iron filings he could process were countless times thinner than a cicada's wing.
Guo Tai Lai was no longer worried about the precision of the single blade. Seeing the position of the new blade, Guo Tai Lai was relieved. As long as there were no problems with the processing procedures that second brother had written, then there would be no problems with everything.Second Brother did not disappoint Guo Tailai and Professor Wang's trust, the processing program was very detailed. Because it was written as a testing program, there were some jobs that could be done in one cut. Sometimes, it would even be deliberately done by dividing the work into different kinds of knives from different angles.
After seeing a few repeated movements, two academicians could not help but furrow their brows and ask. Professor Wang explained softly, and both of their eyebrows relaxed again. Indeed, for the sake of testing, the simple process was deliberately complicated. If a complicated process like changing the head of a knife could be done, then he would be able to do the same without changing the head of the knife.
It was just a seemingly simple metal basketball net, but the process took more than half an hour. However, none of the spectators felt frustrated. Watching the metal basketball net changing its angle in the processing center, bit by bit turning into their expectant looks, everyone felt an indescribable happiness in their hearts.
Finally, when all the processing procedures had been completed, the processing shaft returned to its original position, and the knife and disc returned to their standby state. Only then did the red light, which indicated that it was in the process, turn into a green light and finish processing.
"Take it out and let's see." At the back, a leader of the Information Industry Department could no longer hold it in and quickly gave the order.
The glory of taking out the first work piece was handed over to the designer of the processing center, Professor Wang. No one had any objections towards this.
"Put on your gloves, Teacher Wang." Guo Tai Lai reminded Professor Wang that if he were to take the ultrhigh precision processing equipment with his bare hands, the change in temperature would also affect the accuracy of the measurement.
Professor Wang used both hands to carefully take out the metal basket. The Central TV cameraman had recorded this scene very clearly. Today, the head of the information industry department was present, and it was extremely significant. Central TV had also sent a reporter to record the entire process.
A series of testing tools were installed in a nearby room with a high precision and no dust. The various roundness, length, and diameter were carefully measured and recorded. Even the cameramen at Central TV could only record the measuring process through the windows.
"Total machining error, less than 0.2 μm." When the two Master s who were performing the Laser Beams announced the result, the crowd outside burst into cheers.
With a processing error of less than 0.2 micron, this was already the international frontier of high precision processing center. How could one not be excited when one got such a result on one's first trial?
Including Professor Wang, the few scholars and the professors who were involved in the research all felt hot tears welling up in their eyes. China also had its own independent design and production of super high precision five axis NC Machining Center. Even the leaders of the letter-producing department were excited. From today onwards, they would no longer have to look at the expressions of others.
"However, there is a strange phenomenon." Just as everyone was getting excited, one of the Master who was in charge of measurement said while suppressing his excitement, his face revealing a strange expression.
Strange phenomenon? Is there a problem with the accuracy? Is it unstable? Everyone's hearts thumped, looking at Master's expression, they were all shocked."It's not a bad thing." When Master saw everyone's expression, he immediately knew that they had misunderstood and quickly explained, "All of the sizes that we measured were all accurate to 0.2 micron readings. However, the measuring accuracy of this laser compared to the long meter was only this high. "Therefore, we suspect …"
"Suspect what?" A leader of the letter-producing department asked anxiously. It was not a bad thing, but it would not do if it was not so good! My heart can't take it!
"There is a possibility in this situation." Professor Wang took over the conversation and looked at Guo Tai Lai as if he was asking for confirmation. When he saw Guo Tai Lai nodding, he finally relaxed and couldn't hide the smile on his face: "Actually the processing precision is higher than this, but our measuring tool is unable to measure it accurately now. For the time being, the school does not have a more accurate measuring instrument. "
"If you lack any equipment, report it to me. I'll approve it right away!" The leader's mood once again rose to its peak, just like a roller coaster. Following that, he burst out in uncontrollable laughter.
"Hahahahahaha …"
