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.

Abstract: A bend angle correction method directed to carrying out simple and accurate penetration of a movable die into a fixed die to produce a uniform angle throughout the length of a workpiece, being unaffected by material variations. When bending a sheet-like workpiece to a desired angle by the cooperative movement of a movable punch driven by three or more drive shafts and a fixed die disposed in an opposing relationship with the movable die, the bend angle of the workpiece is measured during bending operation and the difference between the measured bend angle and a target angle is obtained, at at least three points which are the ends and center of the workpiece. Based on the differences, correction amounts for the penetration of the movable die are obtained on a shaft-load imposed point basis.
