Chapter 502: Significant Improvement

Li Mingyuan nodded: "Not only that, 'Nuwa' can also automatically annotate dimensions, generate engineering drawings, and even perform stress analysis and fluid simulation."

He tapped the keyboard a few times, and the 3D model on the screen immediately converted into standard engineering drawings, with various views neatly arranged, key dimensions automatically annotated, and even material specifications and machining requirements included. This conversion would take at least several days in traditional drafting, but now, it was just a matter of a few mouse clicks.

"My goodness..." the old engineer's legs went weak; if not for the person beside him supporting him, he would have almost knelt on the ground, "This is simply... a miracle..."

Li Mingyuan continued his demonstration: "Next, I will demonstrate 'Nuwa's' most powerful function—Numerical Control Machine Tool machining path generation."

He clicked a few buttons, and colored lines appeared around the model on the screen, representing the tool movement path. A series of numbers and codes scrolled in the window on the right.

"These are Numerical Control Machine Tool machining instructions, which can be directly transmitted to the retrofitted machine tool to achieve automated precision machining," Li Mingyuan explained, "With this system, we can increase manufacturing precision by more than ten times and reduce the scrap rate to below 5%."

"This... this means..." the voice of a person in charge of the manufacturing department trembled.

"It means that all precision components for the Kunpeng, Haiying, and nuclear power plants can be manufactured precisely according to design, no longer limited by manual experience," Li Mingyuan added, a hint of imperceptible pride in his tone, "Manufacturing bottlenecks will be completely broken."

The atmosphere at the scene became almost fanatical. People whispered to each other, their eyes shining with disbelief. Several older scientists even shed tears of excitement; they understood too well what this kind of technological revolution meant.

"Chief Engineer Li," the Deputy Commander of the Air Force finally found his voice, "Are you saying that with this system, we can mass-produce Haiying fighter jets, and the quality is guaranteed?"

"Not only that," Li Mingyuan smiled, "We can further improve the design, test more possibilities, and elevate performance to a whole new level."

He gave another brief demonstration—on the screen, the complete 3D model of the Haiying fighter jet gradually took shape, with every system clearly visible, from the airframe skeleton to the internal structure of the Engine, all precise to the millimeter level. Then, he started a simulation program, and the fighter jet on the screen began to perform various flight maneuvers, simultaneously displaying stress distribution and airflow models.

"This is flight performance simulation, which can predict performance under various conditions before actual manufacturing," Li Mingyuan explained calmly, as if all this were perfectly normal, "This can avoid many test flight risks and accelerate improvement iterations."

A young flight mechanics expert stood up abruptly, the expression on his face nearly manic: "This... this is at least twenty years of technological advancement! We need months just for paper calculations, and this... this is simply..."

Before the words were finished, an irrepressible burst of gasps and intakes of breath erupted in the factory building. Several Military leaders looked at each other, their eyes filled with both ecstasy and deep confusion, along with a trace of vigilance—this kind of technological leap was truly too unusual, almost like a miracle fallen from the sky.

The shock and fanaticism in the factory building had not yet subsided, and Li Mingyuan had already moved to the next segment. He tapped the keyboard lightly, and the "Nuwa" system quickly generated a series of machining codes.

"The theory is beautiful, but everyone cares about the actual results," Li Mingyuan said with a smile, "Now, I will demonstrate how to directly convert design into manufacturing."

He pressed a button, and the screen displayed "Data transmitting...". At the same time, the curtain in the corner of the factory building was pulled back by staff, revealing a machine tool that looked different from the others. It was a precision milling machine that had been thoroughly retrofitted; its appearance was similar to traditional equipment, but many electronic components and Position Sensors had been added. Most striking was a small display screen and digital keypad on the control console, replacing the traditional handwheels and dials.

"This is the first Numerical Control Machine Tool we have retrofitted, codenamed 'Fuxi'," Li Mingyuan introduced, "It is connected to the 'Pangu' Computer and the 'Nuwa' system, and can directly execute machining instructions generated by the Computer."

A mechanical engineering expert walked over cautiously and inspected the machine tool: "Added servo motors and Position Sensors... has closed-loop feedback control... but can this really work? Can precision be guaranteed?"

Li Mingyuan did not answer directly, but walked to a material rack on the side and took out a piece of high-strength alloy blank about 30 centimeters square: "This is a core component of the Haiying vector nozzle. Traditional craftsmanship requires the cooperation of five Advanced Technicians, takes three days, and has a scrap rate of over 60%. Now, please watch how 'Fuxi' completes this task."

Under the nervous gaze of everyone, Li Mingyuan fixed the blank onto the machine tool workbench, and then connected a thick data cable from the "Pangu" Computer to the control console of "Fuxi". A few seconds later, the small screen on the control console displayed "Program received, 28,547 instructions in total".

"Everyone, please step back to a safe distance," Li Mingyuan reminded, "Although 'Fuxi' has multiple safety protection measures, this is, after all, the first public demonstration."

Everyone immediately stepped back, forming a semicircular audience area. Li Mingyuan walked to the control console, took a deep breath, and pressed the green start button.

The machine tool emitted a low hum, the workbench began to move precisely, the spindle slowly descended, and the cutting tool head made contact with the metal surface. Then, a miracle occurred—the machine tool operated completely autonomously, without any manual intervention; the tool head moved precisely according to the preset path, metal shavings splashed like a silver waterfall, and the blank gradually took shape at a speed visible to the naked eye.

"My goodness..." an old engineer muttered to himself, "It is working by itself... completely working by itself..."

Unlike traditional machining, every movement of "Fuxi" was extremely precise, without the slightest hesitation or pause. Cutting depth, feed rate, and tool-changing actions were all precisely controlled by the program. What was most shocking was the machining speed—traditional craftsmanship required constant stopping for measurement and adjustment, while "Fuxi" worked continuously, increasing efficiency by at least ten times.

The factory building was deathly silent; everyone held their breath, staring intently at this technological miracle. Many people subconsciously pinched their arms to confirm they were not dreaming.

Forty minutes later, the machine tool spindle stopped rotating, the workbench returned to its initial position, and the control screen displayed "Program execution complete". Throughout the entire process, there was no manual operation, not a single manual adjustment; it was all completed automatically by the "Pangu" Computer through the instructions generated by the "Nuwa" system.
