Abstract

During tactile surface measurements the contact point between probing tip and surface varies depending on the local surface angle. To reduce the resulting measurement deviation on high slopes a probing principle is investigated that applies a dynamic surface dependent sensor tilt. This probing process and the logics for the angle determination have been evaluated by simulation. A test stand based on a nanometer coordinate measuring machine is developed and fitted with a rotation kinematic based on stacked rotary axes. Systematic positioning deviations of the kinematic are reduced by a compensation field. The test stand has been completed and results are presented.
