Abstract
Verfahren
zum Bearbeiten eines Werkstücks
durch Abtragen mittels eines laserstrahlunterstützten Rotationswerkzeugs, bei
dem
– ein
mittels einer Laserdiode (2) erzeugter Laserstrahl in die Achse
(1) des Rotationswerkzeuges an wenigstens einer Stelle exzentrisch
der Rotationsachse in zumindest eine in dem Rotationswerkzeug untergebrachte
Glasfaser (4) eingeleitet wird,
– der Laserstrahl über die
Glasfaser (4) zu einer Austrittslinse (3) geführt wird, und
– der aus
der Austrittslinse (3) austretende Laserstrahl an einer abzutragenden
Stelle annähernd
tangential oder senkrecht zum Wirkumfang des Rotationswerkzeuges
auf das Werkstück
(5) auftrifft, wodurch die Duktilität der Abtragsschicht erhöht wird.Method for machining a workpiece by removal by means of a laser-assisted rotary tool, in which
A laser beam generated by means of a laser diode (2) is introduced into the axis (1) of the rotary tool at at least one point eccentrically of the axis of rotation into at least one glass fiber (4) accommodated in the rotary tool,
- The laser beam over the glass fiber (4) to an exit lens (3) is guided, and
- The laser beam emerging from the exit lens (3) impinges on a workpiece to be removed approximately tangentially or perpendicular to the effective range of the rotary tool on the workpiece (5), whereby the ductility of the Abtragsschicht is increased.

Aus Veröffentlichungen von Manfred Weck ist Lasergestütztes Fräsen an sich schon 1993 mit außerhalb des Werkzeugs geführtem Laser bekannt (WECK, M. und HERMANNS, C.: Laserintegration in Werkzeugmaschinen. VDI-Z, 1993, Vol. 135, Nr. 5, S. 38–41). Demnach können durch die Integration eines Lasers in ein Drehzentrum typische Laserbearbeitungsverfahren die Produktivität und die Flexibilität einer Werkzeugmaschine erheblich steigern. Der Kenntnisstand über den Einsatz eines Lasers in der spanabhebenden Werkzeugmaschine sei jedoch noch gering. Dieses gelte für die mechanische, die steuerungstechnische und die sicherheitstechnische Integration.Out Publications by Manfred Weck is laser-based mill in itself with 1993 already outside of the tool Laser known (WECK, M. and HERMANNS, C .: Laser integration in machine tools. VDI-Z, 1993, Vol. 135, No. 5, pp. 38-41). Accordingly, by the integration of a laser into a turning center typical laser processing methods the productivity and the flexibility of a Significantly increase machine tool. The knowledge about the Use of a laser in the cutting machine tool is but still low. This applies to the mechanical, the control technology and safety-related integration.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, das Werkzeug von seiner Reibungswärmeerzeugung zu entlasten.Of the The present invention is based on the object, the tool from its frictional heat generation to relieve.
Die Aufgabe wird gelöst durch ein Verfahren mit Merkmalen des Patentanspruchs.The Task is solved by a method having features of the claim.
Damit werden die auf das Werkzeug zu übertragenden Leistungen geringer, die Lager entlastet, die Kontaktkräfte zwischen Werkzeug und Werkstück weiter abgesenkt, der Werkzeugverschleiß minimiert und insgesamt die Strukturierungsmöglichkeit verbessert.In order to will be transferred to the tool Lower benefits, relieves the bearing, the contact forces between Tool and workpiece continue lowered, the tool wear minimized and the total structuring possibility improved.
