After Liu Li finished speaking, a brief silence fell over the office. She could hear her own heart pounding, and her palms were sweating. She secretly glanced up to see Team Leader Chen's reaction.

Chen Siyuan remained expressionless, but his sharp eyes narrowed slightly, as if he were re-examining the young female technician before him. He leaned back in his chair, his fingers unconsciously tapping on the table at a slower pace.

"You just mentioned 'prediction-measurement-feedback-correction'," Chen Siyuan began slowly, his tone unreadable. "Where did you come across this concept?"

Liu Li's heart skipped a beat; this question was somewhat unexpected. She couldn't very well say it came from a knowledge system from the future. She steadied herself and chose a half-truth, half-lies answer: "These are scattered concepts I came across while organizing some early foreign materials. I felt they aligned with our line of thinking, so I borrowed them. The main reason is that I felt it wasn't realistic to rely on accurate calculations the first time to deal with such subtle changes; we needed a method that could be fine-tuned according to the actual situation."

Chen Siyuan hummed in agreement, neither confirming nor denying, and then asked, "Multi-degree-of-freedom compensation... this idea is very complicated. How can you be sure that adding forces in several directions won't interfere with each other, or even exacerbate the deformation?"

This question goes deeper, directly addressing the core difficulties.

Liu Li remained calm. She picked up a pen and quickly drew a simple diagram of a thin-walled cylinder on a blank sheet of paper. "Team Leader Chen, look, it's like this cylinder," she pointed with the tip of her pen. "When turning the outer diameter, the main concern is that it will bulge outwards radially, so we mainly apply a pre-pressure inwards radially. But what if it also has a tendency to elongate axially at the same time?"

She then drew an arrow along the axis. "Then we might need to apply an appropriate, opposite clamping force to the end face as well. These two forces, one mainly affecting the 'thickness' of the tube and the other mainly affecting the 'length,' can theoretically work together instead of clashing, as long as their respective magnitudes and application points are calculated correctly." She paused, then added, "Of course, this requires very precise mechanical modeling and simulation analysis, and it's currently just a preliminary idea."

She tried to explain relatively complex concepts using the simplest language possible. Instead of piling up obscure jargon, she used vivid metaphors like "fat" and "thin" to make the principles intuitive and easy to understand.

Chen Siyuan's gaze followed the movement of her pen, and the lines on his face seemed to soften slightly. He suddenly changed his perspective: "Did you encounter a similar problem in your previous factory? How did you handle it?"

This question returned to Liu Li's most familiar area. She breathed a sigh of relief, and her words flowed much more smoothly: "I've encountered this before! Master Wang, who was my former level eight fitter, often used rudimentary methods when he taught us to process thin-walled sleeves. For example, he would pad the chuck with copper sheets of different thicknesses to adjust the uniformity of clamping, or he would let the parts rest for a period of time before finishing, which is called 'natural aging,' to release some of the stress. Sometimes it worked, sometimes it didn't, it wasn't very stable."

She connected Master Wang's experiential "traditional methods" with the current "prestress compensation" approach, using the actual case of the Hongxing Factory as an example: "Master Wang's method of using copper sheets is actually a passive and imprecise 'stress adjustment.' The method we are thinking of now is to make this experiential adjustment more proactive, more quantitative, and more precise. In principle, it is the same, only the method has been upgraded."

Her analogy immediately brought that seemingly "high-level" or even "whimsical" idea back to solid practical ground, making it seem less ethereal.

After listening, Chen Siyuan remained silent for a long time. He leaned back in his chair, his gaze moving from Liu Li's face to her old notebook filled with sketches and notes, and then back to her cheeks, which were slightly flushed with nervousness and focus.

This young man was more grounded than he had anticipated. Not only did he have the courage to propose new ideas, but he was also able to articulate the underlying principles of those ideas clearly and logically, elevating them to a certain theoretical level while remaining grounded in reality, and he did not shy away from difficulties and risks.

The only sounds in the office were the wind outside the window and the faint hum of machinery.

Finally, Chen Siyuan sat up straight, placed his hands folded on the table, and made a decision.

"I understand the line of thought." He spoke, his tone still flat, but the sharpness of his scrutiny had diminished considerably. "In principle, it has its rationale. It's not just nonsense."

Liu Li's heart jumped into her throat.

“However,” Chen Siyuan changed the subject, “the risks are still very high, and the concerns of most of the comrades in the group are not without reason.”

Liu Li held her breath.

“Alright,” Chen Siyuan looked at her, his eyes filled with clear consideration, “I’ll give you a chance. You can use that old C620 lathe in the corner of the workshop that’s not in use for the most basic principle verification. The factory can only provide limited support. I can approve materials and simple machined parts. But you’ll have to figure out the design for that ‘prestressed fixture’ yourself and talk to the machine repair shop to see if it can be made. I’ll give you a maximum of two weeks.”

He neither fully affirmed nor completely denied it. Instead, he offered a very limited but genuine opportunity to verify it. This was the greatest support he could provide, even under pressure.

Liu Li stood up abruptly, her voice trembling with excitement: "Thank you, Team Leader Chen! I will do my best!"

Chen Siyuan waved his hand, indicating that she could leave. Before Liu Li turned and left the office, he said one last thing: "Remember, let your results speak for themselves."
