A method and system for maximizing process capability in a progressive
forming operation. The method compensates for deviations introduced by
unformed components, and uses closed loop feedback to compensate for
deviations introduced by forming tools. Fiducial features are detected on
an incoming component, and a first compensation value is calculated from
displacement of the fiducial features from an ideal forming location on
the component. Component position with respect to a theoretical forming
position is adjusted according to the first compensation value. Placement
of a feature formed on the component at the adjusted position is detected
and compared to the ideal forming location to obtain a difference value.
A second compensation value is derived from a plurality of difference
values. Forming positions for subsequent incoming components are adjusted
with respect to the theoretical forming position according to first and
second compensation values. A system according to the invention comprises
a loading station for incoming components, an imaging subsystem for
detecting deviations, a computer for calculating compensation values, a
conveyor for positioning components, and one or more forming tools for
forming a feature on the component. The computer subsystem comprises a
central controller for actuating system components, collecting and
storing data, and executing compensation algorithms.
