Abstract
The cylindrical coordinate measuring machine MarForm MFU200 can measure not only rotationally symmetric aspheric samples but also nonrotationally symmetric freeform surfaces. Applying both an optical and a tactile probe system, the measuring processes of the optical freeform surface and fiducials can be combined in a very flexible way. A strategy to measure freeforms including the determination of reference coordinate systems, the measuring process, and the analysis are discussed. In this process, fiducials defining a reference coordinate system are of fundamental importance. It is shown how different positions of fiducials can be measured.
