Paper Abstract

The paper describes the manufacturing and dimensional measurements of high precision work-pieces by PTB, which shall act as test masses (TM) for the satellite-based experiment MICROSCOPE. The manufacturing involves turning of Ti alloys and PtRh10. The measurements were made by in-process tactile probing, coordinate metrology, and form measurement. The high geometrical demands of the project could be fulfilled on both the manufacturing and the measurement sub-projects.
