Method and machine for cutting and removing workpiece parts from a plate-shaped material

A method for cutting and removing at least one workpiece part from a plate-shaped material or a metal sheet, the method comprising:

• cutting the at least one workpiece part by using a cutting beam or jet directed onto the plate-shaped material and separating the workpiece part from the plate-shaped material;
• removing the at least one workpiece part as a removal part from the plate-shaped material remaining as a scrap skeleton by:
• using a lifting device to lift the cut-free workpiece part out of a workpiece supporting plane of the plate-shaped material, or
• using an ejection device to remove the cut-free workpiece part downwards out of the workpiece supporting plane, or
• using gravitational force to remove the cut-free workpiece part downwards out of the workpiece supporting plane;
• before cutting the workpiece part free for removal from the scrap skeleton, cutting at least one sacrificial part adjoining the workpiece part, the sacrificial part partially having a common cutting line with the workpiece part;
• and
• cutting the at least one sacrificial part free from the plate-shaped material before cutting the workpiece part free in the plate-shaped material or scrap skeleton.
