Use of Solid Modeling in Design of M3 Components



Allison Barnard Feeney, Peter Brown


This paper documents the work done for the Molecular Measuring Machine (M3) Project by the Engineering Design Laboratory (EDL) at NIST. The M3 Project is developing and fabricating a device capable of making repeatable measurements of atomic-scale features within a volume of 50mm x 100 m. Extraordinary measures are being taken to isolate the device from mechanical vibrations, thermal loading, and acoustic noise. The finest level of control over mechanical vibrations is achieved through an active vibration-isolation system. The EDL created solid models of the components and assemblies related to the active vibration- isolation systems in order to obtain the mass properties calculations required by the dynamic control system.
