ABSTRACT:
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 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; selecting tools for performing each bending operation; storing data for the selected tools or dies; storing bending press control data for controlling the operation of the bending press 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. 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; arranging small tools on the bending press so that a punch and die are laterally shifted from each other; attaching a small die on a ram 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 and die relative to each other; positioning a workpiece relative to a punch and die; positioning a workpiece relative to a backgauge device; and checking a dimension of a shape of the workpiece after performing a bending operation.
