Abstract

Apparatus for bending an elongate workpiece to a desired configuration includes a memory for storing information representative of the desired configuration and information representative of bending operations to be performed by a bending machine. A position sensor is used to scan a workpiece that has been bent using the bending machine, and thereby generate information representative of the actual configuration of the workpiece. The information representative of the actual configuration of the workpiece is compared with the information representative of the desired configuration and, in the event that there is a difference between the actual configuration and the desired configuration, and the difference is beyond a predetermined tolerance, the information representative of bending operations is modified in a manner such as to reduce the difference.
