Systems and methods for aligning measurement data to reference data

A system to evaluate a manufactured part, the system comprising:

• a processing device;
• and
• a non-transitory, processor-readable storage medium, the non-transitory, processor-readable storage medium comprising one or more programming instructions that, when executed, cause the processing device to:
• generate a point cloud of the manufactured part from measurement data relating to the manufactured part,
• generate a mesh from the point cloud of the manufactured part, wherein the mesh comprises a plurality of nodes,
• determine a normal vector slope, a local second order derivative, and a local third order derivative for each node of the plurality of nodes, wherein the normal vector slope, the local second order derivative, and the local third order derivative at each node provides an angle of curvature at a location on the manufactured part, and
• compare the angle of curvature at the location on the manufactured part with reference data for a nominal part that is representative of one or more expected dimensions of the manufactured part.

A system to evaluate a manufactured part, the system comprising:

• a measuring device;
• a processing device communicatively coupled to the measuring device;
• and
• a non-transitory, processor-readable storage medium, the non-transitory, processor-readable storage medium comprising one or more programming instructions that, when executed, cause the processing device to:
• receive measurement data relating to the manufactured part from the measuring device,
• generate a point cloud of the manufactured part from the measurement data,
• generate a mesh from the point cloud of the manufactured part, wherein the mesh comprises a plurality of nodes,
• determine a normal vector slope, a local second order derivative, and a local third order derivative for each node of the plurality of nodes, wherein the normal vector slope, the local second order derivative, and the local third order derivative at each node provides an angle of curvature at a location on the manufactured part,
• determine a plurality of reference points on a nominal part that correspond to the plurality of nodes, wherein the nominal part is representative of one or more expected dimensions of the manufactured part,
• determine a normal vector slope, a local second order derivative, and a local third order derivative for each reference point of the plurality of reference points, wherein the normal vector slope, the local second order derivative, and the local third order derivative at each reference point provides reference data for the nominal part, and
• compare the angle of curvature at the location on the manufactured part with the reference data.
