Abstract
A method for determining measurement conditions of a roughness sensor having at least one measuring needle, a computer program product and a measuring device for carrying out the method are provided. The measuring needle is positioned on a surface in a rest state and rests on the surface without being moved. Measurement signals are recorded in the rest state. A signal line of the roughness sensor is electrically grounded and measurement signals are recorded in the grounded rest state. Further, a method for measuring a roughness of a workpiece surface by the roughness sensor is provided in which the measuring needle is guided along a surface section of the workpiece surface to be measured and moved in a measurement direction (x-direction). The movement of the measuring needle in a plane (yz-plane) perpendicular to the measurement direction is recorded during the movement of the measuring needle along the workpiece surface.
