METROLOGY SYSTEM FOR MEASUREMENT UNCERTAINTY ANALYSIS

摘要

Certain aspects relate to systems and techniques for acquiring metrology inspection data of manufactured physical parts, identifying measurement uncertainty scores at various stages of the process of manufacturing and inspecting the physical parts, and leveraging the measurement uncertainty scores to evaluate manufacturing setups for the capability to make and/or inspect other parts. The scores can be specific to particular geometric features, and manufacturing setups can be identified for new parts based on the geometric features of those parts. To this end, the metrology system can receive inspection data and tolerance specifications in a variety of formats and convert the data into a standardized feature-based format. Standardized metrology data can be aggregated into appropriate subsets to identify uncertainty attributable to performance of a particular metrology inspector, manufacturing system, or metrology device with respect to specific geometric features of manufactured parts.
