Abstract (en)

[origin: WO2009152878A1] The present invention relates to a machine tool monitoring device having a detecting unit (32) for detecting the presence of at least one type of material in at least one prescribed machine tool region, particularly the machine tool working region (34), by means of spectral analysis of radiation (SR), wherein the detecting unit (32) comprises a sensor unit (44) having at least one sensitivity region (54.2) for detecting radiation in a wavelength range (WL2) disposed in the electromagnetic range, a transmitting unit (42; 64) for transmitting radiation having at least one radiation component in the wavelength range (WL2), and an analysis means (58) designed such that it can detect the presence of at least one type of material in at least one prescribed machine tool region based on the radiation detected by the sensor unit (44), wherein the analysis means (58) is operationally coupled to the transmitting unit (42).
