Abstract

A machine for separative machining of a plate-shaped workpiece that has: a first movement unit for moving the workpiece in a first direction (X); a second movement unit for moving a machining head for the separative machining in a second direction (Y); and two workpiece bearing faces for bearing the workpiece. A gap that extends along the second direction (Y) is formed between the workpiece bearing faces. The machine has a push-out unit having a push-out element, wherein the push-out element is movable at least in the second direction (Y) within the gap so as to press, at a predefined push-out position (AP), against a workpiece part that was cut free from the workpiece during separative machining. The disclosure further relates to methods for pushing out a workpiece part which, in particular, was cut free on such a machine.
