HYBRID MEASUREMENT AND SIMULATION BASED DISTORTION COMPENSATION SYSTEM FOR ADDITIVE MANUFACTURING PROCESSES

摘要

A method and system, the method including receiving a nominal computer-aided design (CAD) model of a component; producing a physical representation of the component based on the CAD model using an additive manufacturing (AM) process; measuring the produced physical representation of the component to obtain measurement data of the physical representation of the component; determining a deviation between a geometry of the CAD model and the measurement data of the physical representation of the component; calculating a nonlinear scale factor using an iterative simulation process; determining a compensation field based on the determined deviation between the geometry of the CAD model and the measurement data of the physical representation of the component and the calculated nonlinear scale factor; modifying the nominal CAD model by the determined compensation field; and producing a physical representation of the component based on the modified nominal CAD model.
