摘要

The present invention is a method (20) according to the invention for determining the measurement conditions of a roughness sensor (12) having at least one measuring needle (14), wherein in a first method step (21) At least one measuring needle (14) of the height sensor (12) is placed on and in contact with the surface (16), and the method (20) is a further second method step (22). Where at least one measuring needle (14) rests on this surface (16) and therefore does not move actively along said surface (16), the roughness sensor (12) The invention relates to a method for recording a measurement signal of at least one measuring needle (14) in the stationary state. Furthermore, in another third method step (23) in addition to the further second method step, the signal line of the roughness sensor (12) is electrically grounded and at least one measuring needle (14). The measurement signals are similarly recorded in this grounded stationary state. The invention further relates to a method (30) for measuring the roughness of the workpiece surface (16) by means of a roughness sensor (12) having at least one measuring needle (14), the method (30) being a roughness. A method (20) according to the invention for determining the measurement conditions of a sensor (12) and a method for guiding at least one measuring needle (14) along a surface segment of a workpiece surface (16) to be measured Step (31) whereby at least one measuring needle (14) is actively moved in the measuring direction (x direction) and at least one measuring needle (14) along the workpiece surface (16) Method step (31), during which the movement of at least one measuring needle (14) in a plane perpendicular to the measuring direction (yz plane) is recorded. The invention further relates to a computer program product and a measuring device (28) for carrying out the method in the roughness sensor (12), the measuring device (28) being designed to carry out the method.
