Forming or separating device, and method for operating same

Forming and/or separating device (10) comprising:

• a first tool part (14) and a second tool part (15),
• a drive (17) that is configured to move the two tool parts (14, 15) relative to one another in order to process an initial workpiece (12) arranged in a working area (19) between the two tool parts (14, 15), in order to obtain a processed workpiece (13),
• at least one image-capturing sensor (20) for capturing at least one image (B),
• an evaluation unit (24) that is communicatively connected with the at least one image-capturing sensor (20), wherein the evaluation unit (24) is configured to determine during the operation of the forming and/or separating device (10) whether a defined operating condition of the forming and/or separating device (10) has been reached and to compare the at least one image (B) captured in this defined operating condition by the at least one image-capturing sensor (20) with an assigned stored reference image (R) and/or reference model and to check based on the comparison whether a disturbance exists.
