In smart factories, tungsten steel cutting blades embedded with miniature acoustic emission sensors are now capable of real-time monitoring of micro-chipping and wear conditions along the cutting edge.

The collected data is uploaded to a digital twin platform, where AI models predict remaining service life and automatically trigger blade replacement commands.

After implementation in a packaging plant, unplanned downtime was reduced by 76%, and material waste decreased by 34%.

This marks the transformation of cutting tools from mere "consumables" to "intelligent terminals," reshaping the logic of lean production.
