<p>A method and system are provided that enable an operator without skills in performing bending operations to easily and quickly perform precise bending operations on a sheet workpiece (w) by following a skilled operator's experience, hints or data. The method may include: storing data for a shape of a part; storing data related to a bending order for manufacturing the part from a workpiece (w); selecting tools for performing each bending operation; storing data for the selected tools or dies (D1; D2); storing bending press control data for controlling the operation of the bending press (20; 22) to perform the bending operations in accordance with the bending order; and storing bending operation support information for supporting an operator for performing the bending operations by using the bending press (20; 22). The bending operation support information may include hints or information regarding at least one of the following operations: attaching a protective tape on the shoulder of a die (D1; D2); arranging small tools (P5'; P6'; D6'; D5') on the bending press (20; 22) so that a punch (P1; P2) and die (D1; D2) are laterally shifted from each other; attaching a small die (D5'; D6') on a ram (43) with a fixing tape; aligning a punch and die relative to each other in a longitudinal direction; determining an original point of one of the punch (P1; P2) and die (D1; D2) relative to each other; positioning a workpiece (w) relative to a punch (P1; P2) and die (D1; D2); positioning a workpiece (w) relative to a backgauge device; and checking a dimension of a shape of the workpiece (w) after performing a bending operation.</p> |
