A monitoring device of a machine tool, in particular a circular saw bench, includes a safety unit having at least one first sensor. The monitoring device further includes at least one reference sensor, which is provided to convert a characterizing physical measured variable of the workpiece into an electric characteristic variable during machining of a work piece using the machine tool. The characteristic variable is provided to establish a reference value for a signal of the first sensor.

Monitoring device of a machine tool

A machine tool monitoring device includes a monitoring unit for monitoring a machine tool working region, which is provided in particular for detecting the presence of a material type, in particular human tissue, in the machine tool working region. The machine tool monitoring device further includes a safety unit which outputs at least one safety status signal depending on at least one parameter.

Machine tool monitoring device

The invention is based on a power tool, in particular a stationary saw, having a guard device which has a guard element. It is proposed that the guard device has an actuator system, which is provided for monitoring an opening which is formed at least by the guard element and is adaptable to at least one geometric feature of a workpiece.

Power tool

A machine tool, in particular a sawing machine, is described, having a work surface () for placing a workpiece () to be machined and a tool support unit () for supporting a tool (), the tool support unit being supported movably relative to the work surface (). The machine tool includes a tool operation monitoring device () for monitoring a tool range () at least during tool operation, the device having an imaging unit ().

Machine tool

A power tool includes a lighting unit directed towards a detection field on a workpiece side, and a detection system that emphasizes the contrast between a marking applied to an underlying surface and the underlying surface.

Power tool, particularly a hand-held power tool

A machine tool monitoring device includes a detection device () for detecting the presence of a type of material, in particular human tissue, in a machine tool area () via spectral evaluation of radiation (S). The detection device () includes a sensor unit () having at least one sensitivity range () for detecting radiation in a wavelength range (WL) located at least partially in the infrared spectrum ().

A machine tool monitoring device having a detection unit, which is configured to detect the presence of a material type in a machine tool work area by spectral analysis of a radiation. The detection unit has a sensor unit having at least one sensitivity region for detecting radiation in a wavelength range that is situated at least partially in the infrared spectrum.

A machine tool, in particular a stationary saw, includes a worktable and a safety device which is designed to trigger a reaction as a function of a safety signal, and which includes a signaling device which displays a state of the safety device. The signaling device includes a display which is located on a surface of a worktable and/or above the surface of the worktable.

A machine tool protection apparatus, for a machine tool, that is provided for monitoring of a protection region associated with a tool, including a first sensor unit that is provided for reception of a first protection signal. The machine tool protection apparatus further includes at least one second sensor unit that is provided for reception of a second protection signal.
