Multidirectional roughness measurement insert for determining a measured variable that is characteristic of the roughness of a surface, having a carrier body on which a stylus holder is arranged for holding a stylus, an analog sensor, which converts the movements of the carrier body into measurement signals that are characteristic of the roughness of a surface of workpiece, a stylus to be coupled to the carrier body, comprising a rod-shaped shaft and a scanning head mounted on the shaft, wherein the scanning head is at least one section of a test body, which is essentially rotationally symmetrical to at least one section of the rod-shaped shaft, or wherein the scanning head is at least one section of an essentially rotationally symmetrical test body, which is arranged on a distal end of at least one section of the rod-shaped shaft.

Roughness measuring instrument for use in a machine tool and method for measuring roughness in a machine tool

To determine the position of rotationally drivable tools in machine tools, the moment of separation of the tool to be measured and a measuring beam, for example a laser beam of a light barrier, is used. The tool to be measured is first positioned in such a manner that the measuring beam is interrupted, and is then moved to a measuring position in which the moment of separation of the tool and the measuring beam occurs, and the measuring beam is no longer interrupted by the tool during at least one complete revolution. The moment of separation is used to determine the position of the tool.
