Abstract
A system and method for characterizing surfaces includes using a measuring device to take size measurements of a manufactured product. The raw measurement data is transformed from a time-based domain to a frequency-based domain using a mathematical algorithm. The transformed size measurement data is then compared to predetermined limits within comparable frequency bands to characterize the surface of the manufactured product.
Claims20
A method for characterizing surfaces comprising:
- taking size measurements of a respective feature of a plurality of manufactured products over time;
- transforming the size measurements to frequency-based domain size measurement data;
- comparing at least some of the frequency-based domain size measurement data to a predetermined limit to characterize the surface of the features of the manufactured products;
- and
- separating at least one of the manufactured products based on the characterized surface finish.

A method for characterizing surfaces comprising:
- measuring a diameter of a respective feature of a plurality of products over time;
- transforming the diameter measurement data to frequency-based domain diameter measurement data;
- comparing a subset of the frequency-based domain data for each of the products to a predetermined limit to characterize the surface of the features of the products;
- and
- separating at least one of the products based on the characterized surface finish.
2 more elements
A system for characterizing surfaces, comprising:
- a control system having at least one controller and configured to receive information related to size measurements of a feature of a manufactured product taken over time, the control system being further configured to transform the size measurement data to frequency-based domain size measurement data, and compare at least some of the frequency-based domain size measurement data to a predetermined limit to characterize the surface of the feature.
