Abstract

A computer program includes data defining tool paths for manufacturing a component. The component geometry is estimated based on the program. Deviation of a first type is estimated as deviation between the estimated geometry and geometry of the component as defined by a 3D model. Deviation of a second type is estimated, based on machining process characteristics indicated by sensor data captured during manufacturing of the component, as deviation between a tool path a machine is instructed via the program to provide and an actual tool path provided by the machine. Deviation of a third type is computed as deviation between geometry defined by the 3D model and measured geometry of the manufactured component. An error propagation model is updated based on the estimated and computed deviations for multiple components. The error propagation model approximates relations between deviations of the first and second type and deviations of the third type.
