Dynamic identifying and tracking framework for cutters using RFID technology in digital workshop

For effectively solving the problem of accurate tracking and control of cutters in digital workshop, this paper presents a novel RFID-based dynamic identifying and tracking framework for cutters in digital workshop (RFID-DITF-CDW). An overall architecture for RFID-DITF-CDW is established and its key enabling technologies including RFID-based realtime information collecting, dynamic misuse detecting of cutter change on CNC machines, real-time position identifying, status tracking, and service life forecasting for cutters are discussed. Finally, a prototype system of RFID-DITF-CDW is developed and applied in a real typical CNC machining workshop to demonstrate the validity of presented framework and enabling technologies.
