- Material property adaptation: JS company processes more than 50 materials (metals, composites, etc.), each with processing characteristics that make it difficult for AI to fully grasp the impact of material microstructure on shaping, relying only on material selection recommendations from engineers.
- Quality control boundaries: In the JS case, for example, 98% of orders were delivered on time, relying on engineers to adjust processing errors in real time. Currently, AI cannot dynamically respond to variables such as machine tool state, ambient temperature and humidity.
3.The manifestation of collaborative value
<테이블 스타일 = "Border-Collapse : 붕괴; 너비 : 100%; 경계 넓음 : 1px; 경계 색상 : #000000;" Border = "1">Algorithms are tools, experience is irreplaceable
The practical logic of JS: Using generative AI for initial design exploration (such as quickly generating multi version shell structures), followed by engineers screening and optimizing based on CNC process constraints (such as JS's ±0.005mm tolerance), material properties (such as titanium alloy processing temperature), and customer case experience (such as batch consistency of automotive molds).
Generative AI can improve design efficiency, but the core of machining CNC experience and quality control-still needs to be led by senior engineers. The success of JS demonstrates that the human-machine collaboration model (AI assisted+manual verification) is the most optimal solution for current manufacturing.
