Rosemary Astheimer (Fed)

Mechanical Engineer

Rosemary Astheimer is a Mechanical Engineer in the Smart Connected Manufacturing Systems group. She works closely with industry and standards consortiums to improve the exchange of digital product data using a Model-Based Definition (MBD). Her focus is on the development of ISO 10303 Standard for Product Model Data, also known as STEP (STandard for the Exchange of Product model data), a computer-interpretable representation and exchange of product manufacturing information. She is an active member of several subcommittees of ISO SC4/TC 184 including: WG12 - STEP product modeling and resources; T1 - Migration of STEP Resource Module Library, TF2 - Reference model for computer-readable standards for industrial data; and WG 15 - Digital Manufacturing. She is also involved in several projects investigating the use of Universally Unique Identifiers (UUID) to provide traceability of requirements and features throughout a product lifecycle, in collaboration with the Commonwealth Center for Advanced Manufacturing (CCAM) and PDES, Inc.

She participates in the CAx Interoperability Forum using her in-depth experience with major CAD systems, including CATIA V4, V5, NX, Creo, and SOLIDWORKS, and her ASME Y14.5 GD&T Certification to support testing of ISO 10303-21 (STEP) standard vendor implementations. She provides continued support in developing new publicly available test models and pilot test cases, as well as support for the STEP File Analyzer and Viewer that evaluates and presents STEP file contents.

Rosemary led the organization of the technical content for the 2024 MBE Summit held at MxD, a Manufacturing USA Institute, followed by the 2024 QIF Summit organized by the Digital Metrology Standards Consortium. The MBE Summit has brought academia, government, and industry experts together for 13 years to share the challenges, implementation issues, and lessons learned in design, manufacturing, quality assurance, and sustainment of products and processes where a Model-Based approach is used. Proceedings from the event can be found here.

Rosemary is on the Board of Directors of the Digital Metrology Standards Consortium, which established the ANSI Quality Information Framework (ISO 23952:2020).
