Abstract
There is described a method and system for reshaping a component for assembly that may have been deformed pre-assembly and post-fabrication. As-fabricated measurements are used to determine a baseline for the component and as-mounted measurements are used to determine a deformation parameter as a function of the baseline. The component may be reshaped using correction displacements applied to a positioning device of an assembly tool to which the component is mounted for assembly.

A computer-implemented method for reshaping a component mounted on an assembly tool having a positioning device, the method comprising,
- receiving a set of as-fabricated measurements of the component;
- receiving a set of as-mounted measurements of the component, the as-mounted measurements taken at a same position on the component as the as-fabricated measurements;
- determining a baseline for a shape of the component based on the as-fabricated measurements by calculating an initial twist angle for a floor structure by adding a first angle formed between a first pair of measurements and a horizontal plane to a second angle formed between a second pair of measurements and the horizontal plane;
- determining a deformation parameter for the component based on the as-mounted measurements, the as-fabricated measurements, the as-mounted measurements, and the baseline;
- determining a set of correction displacements for the positioning device to reshape the component using the deformation parameter;
- and
- generating control signals for applying the correction displacements to the positioning device.

A computer-implemented method for reshaping a component mounted on an assembly tool having a positioning device, the method comprising:
- receiving a set of as-fabricated measurements of the component by receiving a first pair of measurements reflecting a position of a first pair of pre-established points located at a first end of the component and a second pair of measurements reflecting a position of a second pair of pre-established points located at a second end of the component opposite to the first end;
- receiving a set of as-mounted measurements of the component, by receiving a third pair of measurements reflecting the position of the first pair of pre-established points from the first end of the component and a fourth pair of measurements reflecting the position of the second pair of pre-established points of the second end of the component, the as-mounted measurements taken at a same position on the component as the as-fabricated measurements;
- determining a deformation parameter for the component based on the as-placed measurements and the as-fabricated measurements;
- determining a set of correction displacements for the positioning device to reshape the component using the deformation parameter;
- and
- generating control signals for applying the correction displacements to the positioning device, wherein determining a set of correction displacements comprises defining a rotation point on the component, selecting one end of the component to remain fixed, and determining displacements in x, y, and z for another end of the component about the rotation point.
