Abstract
A method of side-cutting by a turret punch press for improving working efficiency to a large extent. The method comprises a step in which a selected one (5.sub.1) of a plurality of punch chips (5.sub.1 to 5.sub.4) arranged so as to be selectively hit in a punch assembly (1) provided on the upper turret (2) is used for side-cutting a workpiece (6) and the other step in which one end of a part to be cut into a punching piece with the side cutting is cut off by another punch chip (5.sub.2).
