Abstract
An automated method of verifying a part includes scanning the part to create a three-dimensional computer-based model of the part, indexing the computer-based model of the part to a three-dimensional nominal part design, and adjusting the shape of the model to generate an adjusted model with a shape corresponding to the shape of the nominal part design. The adjusted model is compared to the nominal part design to identify variations between the size and configuration of the adjusted model and the target part design are determined. Furthermore, it is determined whether adjusting the part to conform to the nominal part design would compromise the structure of the part.
Claims20
A method of verifying a part, the method comprising:
- scanning the part to create a three-dimensional computer-based model of the part;
- indexing the computer-based model of the part to a three-dimensional nominal part design;
- adjusting the shape of the model to generate an adjusted model with a shape corresponding to the shape of the nominal part design;
- determining variations between the size and configuration of the adjusted model and the nominal part design;
- and
- using information collected while adjusting the shape of the model, determining whether adjusting the part to conform to the nominal part design would compromise the structure of the part.
A method of verifying a part, the method comprising:
- scanning the part in an unrestrained position to create a point cloud comprising a plurality of points each representing a point on the surface of the part;
- indexing the point cloud to a mesh based on a nominal part design;
- adjusting the shape of the point cloud to generate an adjusted point cloud with a shape corresponding to the shape of the mesh, wherein adjusting the point cloud includes—
- (a) selecting a plurality of different load points on the point cloud,
- (b) determining a gap between the point cloud and the mesh at each of the load points,
- (c) identifying the largest gap,
- (d) adjusting the shape of the point cloud to simulate applying a load to the point cloud at the load point corresponding to the largest gap, the magnitude of the simulated load being sufficient to reduce the largest gap to within a tolerance, and
- (e) repeating steps (b) through (d) until all of the gaps are within the tolerance,
- determining variances between the size and configuration of the adjusted point cloud and the mesh;
- and
- using information collected while adjusting the shape of the point cloud, determining whether adjusting the part to conform to the mesh would compromise the structure of the part.
