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.

Method and apparatus for bending an elongate workpiece

A system for automatically manufacturing shims for use between the structural components of an airframe is disclosed. The system includes: a calibration system (53) for evaluating the accuracy of the measurements made by shim gap probes (87) and producing related calibration coefficients; one or more data acquisition units (55) for measuring shim gaps (41) using calibrated shim gap probes (87); a cell controller (57) for producing machine tool numerical control instructions based on shim gap probe measurements; and, one or more numerically controlled machine tools (59) for manufacturing shims based on said numerical control instructions.
