Abstract
A tool device (1) for machining a workpiece (4) by cutting, milling, drilling or grinding, comprising a sensor (20) for detecting a condition of the tool device (1) during machining, wherein the sensor (20) is connectable to a receiving unit (40), which transmits data to an analysis unit (50) for analyzing the received data. The sensor (20) is configured as a fiber optic sensor (20) comprising at least one optical fiber (26) providing an incident optical path (22) and a reflected optical path (24) for a light beam emitted by a connectable light source (30) and with a distal end thereof lying in a surface (14, 74) of the tool device (1) such that the optical path length can be measured.
