Abstract
A machine tool device includes at least one motorized machining tool, at least one, particularly capacitive, sensor unit, configured to detect at least one foreign body in at least one detection area around the machining tool, and at least one closed-loop and/or open-loop control unit configured to trigger at least one action depending on at least one signal from the sensor unit. The sensor unit includes at least one antenna configured to emit at least one electrical and/or magnetic field, which defines the at least one detection area, and/or to detect the at least one foreign body depending on at least one change in the at least one electrical and/or magnetic field.
Claims26
A machine tool device comprising:
- at least one machining tool operably connected to a motor;
- at least one sensor unit configured to detect at least one foreign body in at least one detection area around the at least one machining tool;
- and
- at least one open-loop and/or closed-loop control unit configured to trigger at least one action based on at least one signal from the at least one sensor unit,
- wherein the at least one sensor unit comprises at least one antenna configured (i) to emit at least one electric and/or magnetic field, which defines the at least one detection area, and/or (ii) to detect the at least one foreign body based on at least one change in the at least one electric and/or magnetic field.
