Chapter 497 Machining Center Completion (Part 2)

How to verify that the system as a whole is normal? Don’t you know just by making a workpiece?

Guo Tailai saw a very interesting processing process in the dream of the future, which is to use a five-axis machining center to process a whole piece of metal into a metal basketball hoop, with a rim and a net. The finished product looks quite realistic .

However, the most amazing thing is the machining process. The machining center changes tools and angles, and even the connecting parts of the basket are processed very finely. Guo Tailai mentioned this idea to Professor Wang before starting the assembly. It seemed that Professor Wang was also very interested, and directly arranged a task for the second brother, asking him to make the processing program of this basketball net in advance.

Now there is a whole piece of metal in the five-axis machining center. For the sake of safety, instead of using titanium alloy directly, ordinary steel is used. Just wait for the console to start the machining program, and then the machining process can begin.

Professor Wang nodded to his second brother, who took another deep breath and imported the metal basketball net processing program from the floppy disk. The 3D image of the basketball net was immediately displayed on the working interface.

The few knowledgeable academicians and professors watching from behind showed interest when they saw this processing procedure. For such a complicated finished product, many aspects must be considered in the processing process. Only one workpiece can be processed, and the performance of this machining center can basically be seen.

With the pressing of the start processing button, the machining axis of the machining center began to move rapidly, and then the worktable also began to rotate into place. A milling cutter is automatically selected from the cutter head, fixed in front of the machining axis, and starts to move quickly.

Seeing that the periphery of the metal block was milled into a cylinder, and then the tool was changed to continue processing. A series of movements are extremely smooth, and the processing positioning is also extremely precise. What others see is the precise cutting of the cutter head, but what Guo Tailai sees is that the error of repositioning after changing the tool does not exceed 0.1 microns.

what does this mean? Guo Tailai is very clear that as long as the positioning accuracy is maintained throughout the entire processing process, the processing accuracy of the final product can reach 0.1 microns. This precision, even in the world, is the highest level of processing precision.

The high-precision lathe that Guo Tailai made last time has eight cuts per thread, and there are iron filings on the knife. Now this ultra-high-precision machining center can process at least 80 knives, or even 90 knives, and the processed iron filings are many times thinner than cicada wings.

Guo Tailai is no longer worried about the machining accuracy of a single cutter head. After seeing the positioning after the tool change, Guo Tailai is completely relieved. As long as there is no problem with the processing program written by the second brother, then everything will be fine.

The second brother lived up to the trust of Guo Tailai and Professor Wang, and the processing program was written in great detail. Because it is written as a test program, some jobs can be done with one knife, and sometimes it is deliberately divided into several different tools and different angles for processing.

Two academicians couldn't help frowning after seeing several repeated actions, and asked a question. After Professor Wang explained softly, the brows of the two also relaxed again. Indeed, for the sake of testing, the simple processing procedure was deliberately complicated. If it can be done by changing several cutter heads, then one-time processing without changing the cutter head can definitely be done.

It's just a metal basketball net that looks very simple, but the processing process took more than half an hour. However, none of the people who watched felt irritated. Seeing the metal basketball net constantly changing angles in the processing center, gradually becoming what they expected, everyone felt an indescribable feeling in their hearts. happy.

Finally, when all the processing procedures are completed, the processing axes have returned to their positions, and the cutterheads have re-entered the standby state, the red light indicating that it is being processed turns into a green light at that moment, indicating that the processing is complete.

"Take it out and have a look." A leader of the Ministry of Information Industry couldn't hold back anymore, and quickly ordered.

The honor of taking out the first workpiece was given to Professor Wang, the designer of the machining center. In this regard, no one has any objection, and everyone expects it.

"Put on your gloves, Mr. Wang." Guo Tailai reminded Professor Wang that if you hold ultra-high-precision workpieces with bare hands, changes in body temperature will also affect the accuracy of measurement.

Professor Wang used both hands to carefully lift out the finished metal basketball hoop. CCTV's photographers recorded this scene very clearly. Today, the leaders of the Ministry of Information Industry attended, and it was of great significance. CCTV also sent reporters to record the whole process.

In a dust-free high-precision testing room next to it, there are a series of testing tools. Various roundness, length, and diameter were carefully measured and recorded one by one. Even CCTV photographers could only record the measurement process outside through the window.

"The overall processing error is less than 0.2 microns." Two master students operated the laser ratio meter. When the result was announced, the crowd outside cheered.

With a machining error of less than 0.2 microns, this is already an international cutting-edge high-precision machining center. How can it not be exciting to get such a result in the first test run?

Including Professor Wang, several academicians and professors involved in the research all had tears in their eyes. Huaxia also has a self-designed and self-produced ultra-high-precision five-axis CNC machining center. Even the leaders of the Ministry of Information Industry were excited for a while. From now on, they no longer have to look at other people's faces.

"However, there is a strange phenomenon." Just when everyone was excited, one of the master students in charge of the measurement suppressed his excitement, and said to everyone with a strange expression on his face.

Strange phenomenon? Is there a problem with the accuracy, unstable? There was a thud in everyone's heart, and they were all shocked when they saw the expression of the master's student.

"It's not a bad thing." Seeing everyone's faces, the master student immediately knew that everyone had misunderstood, and quickly explained: "All the dimensions we measure are accurate readings of 0.2 microns. However, the measurement of this laser ratio meter The accuracy is only so high. So, we suspect..."

"What do you suspect?" A leader of the Ministry of Information Industry asked anxiously. It's not a bad thing, but it's okay if it's not so good! My heart can't take it!

"In this case, there is a possibility." Professor Wang took the conversation and looked at Guo Tailai who was not far away with a proving look. He didn't feel relieved until he saw Guo Tailai's nod, and the smile on his face continued. It can't be concealed: "In fact, the processing accuracy is higher than this, but our measuring tools can't measure more accurately. The school does not have higher-precision measuring instruments for the time being."

"What equipment is lacking, just send a report, and I will approve it immediately!" The leader's mood was like a roller coaster, and at this moment it reached the peak again, followed by a sudden uncontrollable laughter.

"Hahahahahaha..."
