Abstract

See full text

A method for multiple-stroke slotting of planar workpieces includes positioning a workpiece relative to a slotting tool having a punch and a die, moving the punch and the die relative to one another, moving the slotting tool and the workpiece relative to one another, slotting a workpiece by a slot length during a sectioning slot stroke and at least one subsequent slotting stroke in a sectioning phase, and performing strokes in form of slotting strokes and at least one trimming stroke during the relative movement of the punch and the die in a working phase. The subsequent slotting stroke is performed prior to the trimming stroke, and the slot length exceeds a maximum attainable slot length during the trimming stroke. The workpiece and the slotting tool are moved relative to one another by at least one feed movement between the strokes.
