Yang Zhongquan stared at the S-shaped test piece in his hand, his eyes full of disbelief.
Don't underestimate it just because it was a thin S-shaped sheet. Technically speaking, its curved surface had been generated by spline curves, which were themselves generated through control points. Apparently, this was similar to how aircraft structural components were created.
Moreover, because this twisted S-shaped test piece contained curved surfaces and sections that formed acute angles with the base—closed corners—it could theoretically only be machined by a five-axis simultaneous machine tool. At the same time, the feed direction had to change repeatedly during machining, placing considerable demands on the machine tool's performance.
Thus, not only machining precision, but attributes such as force, heat, vibration, noise, and so on would ultimately be reflected in the geometric error of the S-shaped test piece's curved surface.
Yang Zhongquan had never seen this machine's original system, but common sense told him that even a custom original system tailored for this machine tool by Siemens would struggle to achieve this level.
Seeing the stunned expression on Yang Zhongquan's face, Lu Zhou guessed that Xiao Ai had probably performed a little too brilliantly, and he could not help worrying about how to explain it.
But then he reconsidered...
Why the hell should I explain anything?
Why should I waste the effort explaining it!
So he put on an expression that said believe it or not and casually made up an excuse.
"When I was studying abroad in Europe, I met a few friends. One of them was an expert in this field. While talking with him, I learned that he was researching a machine tool control system based on neural network learning technology—"
"That's impossible!" Yang Zhongquan's eyes widened as he immediately retorted, "It's not like no one has researched
