Process for operating a plate dividing system， and plate dividing system

In a method for operating a plate dividing system (10)， a plate-shaped workpiece (30) is held at least temporarily by means of at least one clamping device (24) and divided in the clamped state by a dividing device along a dividing line (18). It is suggested that it includes at least the following steps: a. Performing a first splitting process by means of the splitting device， so that a separated workpiece (38a) and a still clamped residual workpiece (40) are produced; b. releasing the clamping of the residual workpiece (40) at least in certain areas such that the residual workpiece (40) can deform due to internal stresses; c. Positioning the rest of the workpiece (40) for a second dividing operation by means of a feed device (22); d. Carrying out the second splitting process by means of the splitting device.
