Abstract

Bending machine with a machine bed including a workpiece table with a workpiece support surface and an upper tool which is linearly movable mounted to the machine bed along a movement axis and which has a bottom edge arranged adjacent to the workpiece support surface. The lower edge and the movement axis define a movement plane which separates a handling space from a workpiece receiving space, in which a first optical safety device is arranged in the handling space and a second optical safety device is arranged in the workpiece receiving space, and with a safety controller to process sensor signals from the optical safety devices and for switching off a drive associated with the upper tool. The safety controller provides a first operating mode, in which only the first sensor signals are processed, and a second operating mode, in which only the second sensor signals are processed.
