ABSTRACT:
A method for determining a helical groove structure, for example in the form of flutes, in the surface of a finely finished cylindrical workpiece, in particular the ground mating bearing surface of radial shaft sealing rings, which is characterized in that a camera is used to record at least one image of the illuminated surface of the workpiece, which image reproduces the helical groove structure in the surface of the workpiece. A device for carrying out a method includes a CCD camera with a macrolens, a radial bearing device for the workpiece, an illuminating device and an image reading and image processing device.
