Abstract: To reduce measurement deviations of tactile surface measurement systems resulting from high surface angles, a probing principle is investigated based on a dynamic surface slope dependent sensor tip rotation. To research the principle, a simulation environment and methods to calculate an optimal tip rotation angle are developed. The achievable deviation reduction of the principle and the performance of the different angle determination methods are examined based on different sample surfaces. In support of a hardware realisation, parameters of a virtual rotation system are varied, its effectiveness is quantified and the limits are identified.
