Abstract
A manufacturing control system for an additive, subtractive, or hybrid machining system implements in situ part inspection to collect as-built metrology data for a manufactured part while the part remains in the work envelop, and uses the resulting measured inspection data to generate an as-built digital twin that accurately models the finished part. After execution of a subtractive and/or additive tooling operation, the system performs a sensor scan to collect three-dimensional imaging measurement data for the resulting manufactured part while the part remains in the work cell. The measurement data is then integrated with as-designed part metadata for the idealized part to yield the as-built digital twin. Since metrology measurements are integrated into the manufacturing process, customized as-built digital twins can be generated for each manufactured part without requiring manual inspections to be performed on each part.
