Abstract
A method for capturing dynamic vibrations of a roughness sensor of a roughness measuring apparatus is provided. The movement of the roughness sensor relative to the roughness measuring apparatus and/or relative to a surface of a workpiece is captured by a measuring system in the frequency range below 100 Hz with a data capturing rate of greater than 100 Hz. The captured data of the relative movement are made available for further data processing in and/or stored. Moreover, a method for measuring the roughness of a workpiece surface is provided, in which the method for capturing the dynamic vibrations of a roughness sensor is used. In addition, a computer program product for controlling a roughness sensor of a roughness measuring apparatus in accordance with one of the methods is provided, and a roughness measuring device that is configured to carry out one of the methods.
