摘要： A method for monitoring the machining of a workpiece with a high-energy processing beam comprises the steps of: recording an electronically evaluatable image which contains at least the point of incidence of the processing beam on the workpiece; generating actual image data; comparing the actual image data with nominal image data; generating an image error signal if the actual image data deviate from the nominal image data; detecting, synchronously with the generation of the actual image data, the actual processing parameters controlling the process to be monitored; comparing the actual processing parameters with nominal processing parameters; generating a process error signal if the actual processing parameters deviate from the nominal processing parameters; generating an error signal when an image error signal and a processing error signal are present simultaneously; and initiating measures if an image error signal is present.
