1. A method for producing workpiece parts from a workpiece in a processing machine or a laser processing machine, the method comprising:
positioning the workpiece on a workpiece support and using a plurality of clamping devices to hold the workpiece along a side edge of the workpiece relative to the workpiece support;
using a process beam to cut a plurality of workpiece parts out of the workpiece;
at least one of using a processing head to move the process beam relative to the workpiece support or using the clamping devices to move the workpiece relative to the workpiece support;
interrupting a cutting process for processing the workpiece to produce the workpiece parts at least once by a relaxation step for the workpiece;
during the relaxation step, releasing the clamping devices along the side edge one after another from an outside of the machine inward, for a relaxation of a partial region of the workpiece and, following the relaxation of the workpiece and before continuing the cutting process, closing the clamping devices; and
keeping at least two of the plurality of clamping devices closed for fixedly holding the workpiece, and subsequently, following the relaxation of the partial region of the workpiece, closing the opened clamping devices again from an inside outward.
