Title: WORKPIECE PROCESSING MACHINE AND METHOD FOR OPERATING THE WORKPIECE PROCESSING MACHINE
Abstract:
The invention relates to a workpiece processing machine (1) and to a method for operating a workpiece processing machine (1). The workpiece processing machine (1) comprises an automatically adjustable stop finger (17) and, for monitoring adjusting movements of the stop finger (17), has a monitoring device (36, 37, 38), which comprises an illuminating device (36) and at least one optical detecting device (37). During an automatically controlled adjusting movement of the stop finger (17) while the workpiece processing machine (1) is in operation, a bundle of light (38) is radiated into an area running ahead of the stop finger (17) in the adjusting direction. If a first light imaging (43) projected by the first bundle of light (38) on an object surface (42) is detected, a safety measure is initiated.
