METHOD FOR IDENTIFYING DEFECTS DURING THE PROCESSING OF CONSTRUCTURAL WORKPIECES AND ASSOCIATED NUMERICAL

In the case of a method for detecting defective products during the machining of workpieces (14) of the same structure by means of a numerically controlled workpiece machining device (10), the method comprises the following steps: a) machining the workpiece (14) by means of a target tool trajectory (34) of a tool (12) specified to the workpiece machining device (10), and b) adjusting a working distance (22) of the tool (12) from the workpiece (14) to a defined target distance, the tool (12) is moved along a target tool trajectory (34) on a distance-adjusted actual tool trajectory (36) during the machining of the workpiece (14), according to the invention, it is checked whether a deviation of the distance-adjusted actual tool trajectory (36) from the target tool trajectory (34) suitable for this workpiece (14) on a selected contour section (40) of the machined workpiece (14) is less than a predefined tolerance value, and if the deviation is less than the predefined tolerance value, the tool (12) is moved along
