A method for splitting of large-sized panel-shaped workpieces, as well as panel-

is for dividing large-sized panel-shaped workpieces (20) on a feed table (12) lying workpiece (20) from a conveyor (24) of a sawing device (32, 30) supplied. It is proposed that the method comprises the steps of: (a) preparing an at least one step (74a, 74b) having first longitudinal edge (76) lying on the on the feed table (12) the workpiece (20) by means of at least one milling device (34) ; (B) cutting off a first longitudinal edge (76) having semi-finished product (50) by producing a rectilinear second longitudinal edge (82) by means of a longitudinal section of the sawing device (30, 32); (C) introducing a Quersageschnitts (88a to 88e) in the separated semi-finished product (50) at least in the region of the step (74a, 74b).
