Photogrammetric 6DOF measurement on machine tools

For the characterization of the thermo‐elastic machine state, the measurement of the TCP displacement and the deformation of the machine assemblies are necessary. The challenge is the measurement of the deformation at a large number of measuring points and the displacement of the TCP simultaneously. A promising approach is to use photogrammetric methods. In this article we present an extended photogrammetric method for the measurement of the deformation and displacement with a test rig on an existing machine tool. The main focus is on the design and commissioning, the realization of a measurement setup as well as first experimental investigations on a machine tool.
