MACHINE TOOL MONITORING APPARATUS

摘要

The invention starts with a machine tool monitoring apparatus with a recognition unit (32) which recognizes the presence of a type of material in a machine tool work area (34) by means of the spectral analysis of an emission of rays (SR). It is proposed that the recognition unit (32) have a sensor unit (44) with at least one area of sensitivity (54.2) for the detection of radiation in a wavelength range (WL2) which is located at least partly in the infrared spectrum.
