Demand for entry-level positions (e.g. operators) may decrease as AI-assisted programming reduces manual programming requirements for beginners; but skilled positions like machine setup and multi-axis machining remain in high demand, and shortages of certified technicians raise entry barriers.
CNC operators should shift to multi-axis/five-axis programming and process optimization, master CAM-AI integrated tools (e.g., Siemens NX AI machining assistant), and develop capabilities in automation unit commissioning like robot loading/unloading and online inspection. Future upgrade to automated production line supervisor or precision machining process engineer, with significantly increased salary and irreplaceability.
