Abstract
A system and method of making a part, including capturing an actual tridimensional surface of each part to obtain a corresponding digitized actual surface, performing a tridimensional comparison between the digitized actual surface of each part and a nominal tridimensional surface, generating an actual location and orientation of an operation to be performed based on the tridimensional comparison, and performing the operation on the part based on the generated actual location and orientation of the element.
Claims13
A method of making a part, the method comprising:
- providing a nominal tridimensional part definition including a nominal part surface, and a nominal location and orientation for at least one geometrical element on the nominal part surface;
- capturing an actual tridimensional surface of the part to obtain a corresponding digitized actual surface;
- performing a tridimensional comparison between the digitized actual surface and the nominal part surface;
- generating an actual location and orientation of each geometrical element on the digitized actual surface based on the tridimensional comparison;
- and
- providing each geometrical element on the actual surface based on the actual location and orientation of the element on the digitized actual surface.
A machining system for providing to a machine tool an actual location and orientation of a plurality of elements to be machined on a part, the system comprising:
- a scanner for capturing an actual tridimensional surface of the part and defining a digitized actual surface representing the actual tridimensional surface;
- a comparator for performing a tridimensional comparison between the digitized actual surface and a nominal tridimensional surface of the part to determine a best fit between the digitized actual surface and the nominal surface;
- and
- a compensation calculator for generating the actual location and orientation of each of the elements on the actual digitized surface based on a nominal location and orientation for each of the elements on the nominal surface and on the best fit between the digitized actual surface and the nominal surface.
