The paper focuses on comparative experiment on manufacturing and inspection of two different prismatic one-off parts, which have different complexity. Our experiment shows that transforming product definition method from the Drawing Centric Definition (DCD) to the Model Centric Definition (MCD) enables 28%-29% time savings in manufacturing and inspection phases of machined one-off part’s life cycle. Furthermore, transition from MCD to Model-Based Definition (MBD) enables 5%-9% time savings, respectively. Applying of MBD enables more time savings in complex part compared to a less complex part.

Keywords: model-based engineering (MBE), computer-aided design (CAD), 3D modelling
