Abstract: The method for laser-support shaping for ductile ablation- with device for beam-guidance, -forming, and -guiding, comprises guiding the laser beam in an eccentrically proximate axis parallel direction to spindle/tool axis using multifunction-beam forming-ring-prism, with a beam forming-mirror-surface and further mirror-surface with beam formation characteristics, for transition on the discharge area through structuring for beam diversion- and formation for removing chip. An interior-ring-prism integrated in tool holder is used with forming and beam guiding characteristics. The method for laser-support shaping for ductile ablation- with device for beam-guidance, -forming, and -guiding, comprises guiding the laser beam in an eccentrically proximate axis parallel direction to spindle/tool axis using multifunction-beam forming-ring-prism, with a beam forming-mirror-surface and further mirror-surface with beam formation characteristics, for transition on the discharge area through structuring for beam diversion- and formation for removing chip. An interior-ring-prism integrated in tool holder is used with forming and beam guiding characteristics that receives beam from the spindle means and conducts the beam in axis parallel direction of the tool axis. Element transmitting as power functions between the tool and the reception. The multifunctional external-ring-mirror-prism is irradiated approximately right-angled to the tool-axis and is integrated into the tool reception or into the tool shaft. The multifunctional individual prism is positioned in a place that enables beam guidance approximately right-angled from the horizontals into verticals in a plain near to the shaft. The tool position adapted to tool diameter arises in the right-angled plain. A multifunctional-prism is used for approximately right-angled irradiation of laser conducting labels or standard function-element such as fiber-to-fiber coupling is guided with one of the discharge side in the pure glass fiber in a narrow bend and the laser beam is guided directly from the fiber for further forming in individual prism or the external-ring-prism (3). All-round processing and cw-laser-utilization of the device is integrated at 360[deg] with the beam angle over a drive with corresponding place around the axis of the spindle and the tool for focus positioning in actual shaping direction before the shaping in chip area. Point of the normal of the shaping radius on the workpiece surface to recess determines after standard-C-axis-control as C-axis, with an offset corresponding over an oscillation sensor in correspondence with the momentary angle position of the maximal chip removal power of the reference tooth. The circumference-shaping-bow-tools are used in which the beams discharge right-angled to the rotation axis from the shaping diameter, where the ductile effect emerges in a bow groove or separation groove. The tool receptions are provided with tools for scanning, welding and polishing.
