Abstract

A laser beam transmission system for moving elements preferably. in tools to support ductile removal comprises simultaneous distance measurements to workpiece surfaces to be machined or not. A rotating resonator mirror with partly reflecting passages from the tool shank directs the beam to give ductility in the cutting area.

Description

Laserstrahl-Übertragung auf bewegte weiterführende Elemente vornehmlich in Werkzeuge zur Unterstützung des duktilen Abtrags ist eine Weiterentwicklung des bei Einkorn duktilen Drehen bereits eingesetzten Lasers der im Vorfeld des abtragenden Korns das Material erhitzt um die Belastung des Korns zu minimieren und eine Tiefenschädigung in Grundmaterial zu vermeiden.Laser beam transmission to moving advanced elements primarily in tools to support ductile stock removal is a further development of the ductile turning already used at Einkorn Laser that heats the material in advance of the abrasive grain to minimize the load on the grain and damage the depth of the base material to avoid.

Es wurde bereits der Versuch unternommen diese vorteilhafte Bearbeitung auch auf das Fräsen anzuwenden, da allerdings bei z.B. Fünf-Achs-Maschinen fünf weitere Achsen nötig wahren um den Laser vor dem Werkzeugeingriff zu steuern scheitere die Anwendung an zu hohen Maschinenkosten.Attempts have already been made to do this to apply advantageous machining to milling, however at e.g. Five-axis machines five more Axes necessary true to control the laser before the tool failure fail Application at too high machine costs.

Diese Erfindung umgeht die Extrasteuerung in dem der Laser über das Werkzeug an den Abtragspunkt gebracht wird und außerdem den Gesamtenergieeintrag mindert da der Laserstrahl unmittelbarer an den Abtragspunkt gebracht werden kann.This invention circumvents the extra control in which the laser over the tool is brought to the removal point and also the The laser beam reduces total energy input more directly the removal point can be brought.

Die Laserausführung nach Anspruch 1 bedeutet eine Aufteilung der üblichen Bauart eines geschlossenen Systems in zwei Teile – 1. den Laserteil 1 1-5 und 2. einen rotierenden Resonatorspiegel 6 mit wenigstens einem blendenartigen teildurchlässigen Fenster 7,8 das konzentrisch zur Rotationsachse 10 angeordnet ist. Nach Anspruch 2 ist die Verwendung eines kontinuierliche strahlenden Lasers herkömmlicher Bauart vorgesehen.The laser design according to claim 1 means a division of the usual design of a closed system into two parts - 1 , the laser part 1 1-5 and 2 , a rotating resonator mirror 6 with at least one panel-like, partially transparent window 7 . 8th that is concentric to the axis of rotation 10 is arranged. According to claim 2, the use of a continuous radiating laser of conventional design is provided.

Insbesondere für ,Lasergestützten Hoch-Geschwindigkeits-Abtrag', ist der Resonatorspiegel 6, die Konkavspiegel zwischen den weiterführenden Elementen 7 und 8 mit den Elementen, der geschlossene Linsenring aus Linsen 15 in 3 oder der Teilkreis weiterführender Element 18 in 4, die Werkzeugkopf abgewandte Stirnfläche eines Werkzeugschaftes vorzugsweise nach P.3911769. Die prinzipielle Anwendung ist bereits in der Patentanmeldung 199 62 126.8 enthalten.The resonator mirror is especially for 'laser-assisted high-speed removal' 6 who have favourited Concave Mirrors Between Continuing Elements 7 and 8th with the elements, the closed lens ring made of lenses 15 in 3 or the graduated element 18 in 4 , the end face of a tool shank facing away from the tool head, preferably according to P.3911769. The basic application is already contained in patent application 199 62 126.8.

Wirkungsweise nach Ausführungsbeispiel 1 Mode of operation according to the embodiment 1

Mit den Teilen 1 – 5 wird der Laserstrahl erzeugt als kontinuierlicher Strahl oder auch gepulst mit 1-10ns. 1 Konstant- Lichtquelle oder Pumplicht-Blitzlampe 2 Aktives Medium Lichtverstärkender Festkörper 3 Eliptischer Spiegel-Hohlkörper zur Lichtkonzentration 4 zwei Brennpunkte 1mal Lichtsendung 1mal Lichtsammlung 5 Resonator-Spiegel Totalreflektion. Während der Überdeckung der Fläche 6 mit dem weiterführenden Element 7 kann der Laserstrahl austreten und wird zum Bearbeitungsbereich geführt. Nach Weiterdrehung des Werkzeugschaftes um die Rotationsachse 10 wird die totalreflektierende Spiegelfläche vom Laserstrahl 9 getroffen und dieser zurück in den Laserkörper geworfen um dort den nächsten Impuls zu verstärken bis ein erneuter Austritt in die nächste Glasfaser erfolgt.With the parts 1 - 5 the laser beam is generated as a continuous beam or pulsed with 1-10ns. 1 Constant light source or pump light flash lamp 2 Active medium light-amplifying solid 3 Eliptical mirror hollow body for light concentration 4 two focal points 1 light emission 1 light collection 5 Resonator mirror total reflection. While covering the area 6 with the continuing element 7 the laser beam can exit and is guided to the processing area. After further rotation of the tool shaft around the axis of rotation 10 becomes the totally reflecting mirror surface from the laser beam 9 hit and thrown it back into the laser body to amplify the next pulse there until it emerges again into the next glass fiber.

Insbesondere beim lasergestützten Abtrag durch rotierende Werkzeuge treten Frequenzschwankungen der Drehfrequenz auf die auf diese Weise eliminiert werden, so dass keine Frequenzerfassung und Steuerung erforderlich ist.Especially with laser-assisted removal rotating tools occur frequency fluctuations in rotational frequency to be eliminated in this way, so no frequency detection and control is required.

Grundsätzlich ist es so, dass der rotierende Spiegel geringerer Wärmebelastung ausgesetzt ist und das besonders belastete teildurchlässige Fenster vielfach vorhanden ist und damit ebenfalls geringer belastet wird. Zudem bewegt sich beides im Kühlmedium. Durch gute Abkapslung kann für einen Überdruck gesorgt werden der eine Verschmutzung unterbindet.Basically, the rotating mirrors with lower heat load exposed and the particularly stressed partially permeable window is often present and is therefore also less polluted. In addition, both move in the cooling medium. By good encapsulation can for an overpressure care is taken to prevent pollution.

Wirkungsweise nach 2 Mode of action after 2

Diodenlaser mit kontinuierlichem Laserstrahl geben ihre Nennleistung nur bei ununterbrochener Strahlung ab. Dieser Strahl muss dem Verlassen eines weiterführenden Elementes auf einen konkav gebogenen Spiegel zwischen je zwei weiterführenden Elementen treffen damit er in Folge der Drehung des Werkzeugschaftes von dort gespiegelt auf den Spiegel neben der Austrittslinse des Lasers trifft und von diesem kontinuierlich auf das zunächst folgende weiterführende Element gespiegelt wird solange bis dieses den Strahl direkt erreicht. Auch bei dieser Ausführung wird eine Frequenzerfassung der Drehung unnötig.Continuous diode laser Laser beams only give their nominal power when there is uninterrupted radiation from. This beam must be leaving a further one Element on a concave curved mirror between two further elements hit it from there as a result of the rotation of the tool shank the mirror next to the exit lens of the laser and from this continuously to the following element is mirrored until it reaches the beam directly. Also in this version frequency detection of the rotation becomes unnecessary.

Beschreibung nach 3 Description after 3

Die Linsen, hier Grin-Linsen, werden seitlich angeflächt – Ein zelheit C und Schnitt D-E das sie Stück für Stück aneinadergelegt einen geschlossenen Linsenring bilden wie in Ansicht A. Der Laserstrahl 9 findet so übergangslos, bei den Übergängen aufgeteilt auf 2 Linsen immer Durchgang zu den weiterführenden Elementen – heute Glasfasern. An der Schnittstelle kann die Glasfaser mit der Linse verklebt werden.The lenses, here grin lenses, are flattened on the side - a detail C and section DE that are placed one by one to form a closed lens ring as in view A. The laser beam 9 so there is no transition, with the transitions divided into 2 lenses, there is always passage to the further elements - today glass fibers. The glass fiber can be glued to the lens at the interface.

Beschreibung nach 4 Description after 4

Bisherige Schnittstellen beschränkten sich auf das Werkzeug welches bedeutete das die gesamte Einkopplungsoptik in jedem Werkzeug vorhanden sein musste.Previous interfaces were limited to the tool which meant that the entire coupling optics had to be present in every tool.

Außerdem war es erforderlich das jedes Werkzeug mit einem Hülsenkörper 21 einschließlich der Lager und dem Antriebsritzel ausgestattet war, was zusätzlich zu einem völlig neuem Werkzeugwechsel-System geführt hätte.It was also required that each tool with a sleeve body 21 including the bearings and the drive pinion, which would have resulted in a completely new tool change system.

Die Einbringung der zusätzlichen Schnittstelle 20 erlaubt es das Antriebsriutzel mit Einkopplungsoptik und Schnittstelle 17 in die Maschine zu integrieren, so dass der werkzeugseitige Aufwand auf lediglich weiterführende Glasfasern auch kegelförmig wie in 1 beschränkt werden kann was bei der Vielzahl von Werkzeugen erhebliche Kostenersparnis bringt.The introduction of the additional interface 20 allows the drive belt with coupling optics and interface 17 to be integrated into the machine, so that the effort on the part of the tool on only further glass fibers is also conical as in 1 can be limited, which brings considerable cost savings with the large number of tools.

Da nun die eben erwähnten Umgebungsteile ebenfalls in die Maschine integriert werden können, ist man quasi beim bisherigen Werkzeugwechsel und hat zudem eine hermetische Abdichtung zwischen Werkzeugen und Laser in der Maschine.Since the surrounding parts just mentioned also can be integrated into the machine, you are practically the previous one Tool change and also has a hermetic seal between tools and lasers in the machine.

Generell können nach jeweiligen Stand der Technik die weiter führenden Elemente auch Kunststofffasern oder Hohlfasern auch innenverspiegelt sein.In general, according to the current status the leading technology Elements also plastic fibers or hollow fibers can also be internally mirrored.

Laseraustrittlaser exit

Der Austritt des Laserstrahls z.B. nach Ausführungsbeispiel 5 erfolgt aus dem Faserende welches zur besseren Fokussierung auch noch düsenartig verjüngt sein kann.The exit of the laser beam, for example, according to the embodiment 5 takes place from the fiber end which can also be tapered like a nozzle for better focusing.

Es muss die polare Beweglichkeit um Minimum 180 Grad des Laser-Objektiv um die Werkuzeugachse zur grundsätzlichen Festlegung an welchem Umfangsteil des Werkzeuges der Strahlaustritt konform mit dem Werkstück-Kontakt erfolgt gegeben sein. Darüber hinaus solten für verschiedene Werkzeuggrößen zwei oder drei Einführungsteilkreise in der Einkopplungseinheit vorhanden sein, die dann allerdings auch über eine radiale Positionierachse angefahren werden müssten.There must be polar mobility around minimum 180 degrees of the laser lens around the tool axis to the basic one Definition of the circumferential part of the tool conforming to the beam exit with the workpiece contact be given. About that out for different tool sizes two or three introductory sub-circles be present in the coupling unit, but then also via a radial positioning axis would have to be approached.

Weiter kann die Austrittsrichtung auf die Abtragsstelle direkt 24 und 29 gerichtet sein oder auf das Material welches zum Abtrag ansteht 25 und 30 auch je auf beide Stellen.The exit direction can continue directly to the removal point 24 and 29 be directed towards the material to be removed 25 and 30 also on both positions.

Da das Werkzeug eine Umfangsgeschwindigkeit hat wird der Strahl schon dadurch gestreut. Der Wirkbereich kann noch vergrößert werden wenn jede Strahlrichtung etwas geändert wird. Auch kann die polare Verstellbarkeit oszillierend gemacht werden um den Wirkbereich des Laseraustritts zu vergrößern.Because the tool has a peripheral speed has already scattered the beam. The effective range can still be enlarged if every beam direction is changed a little. Also the polar one Adjustability can be made oscillating around the effective range of the Enlarge laser exit.

Insbesondere bei Fingerfräsern sollte zwischen zwei Schneiden mehrere Faseraustritte vorhanden sein wegen des relativ geringen Durchmessers und der begrenzten Zahl von Schneiden.Especially with end mills There should be several fiber exits between two cutting edges the relatively small diameter and the limited number of cutting edges.

Bei Walzenfräsern müssen zwischen zwei Schneiden generell mehrere Faseraustritte an wechselnden Stellen angeordnet sein.With milling cutters, there must be between two cutting edges generally several fiber outlets arranged at different points his.

Generell ist es bei diesem Verfahren ratsam die Anzahl der Schneiden so hoch wie eben möglich zu wählen damit die Einzelspan-Volumina minimiert und die Eingriffsfrequenz maximiert werden. Außerdem muss aus gleichem Grund die Umfangsgeschwindigkeit maximal ausgelegt werden.Generally it is with this procedure It is advisable to increase the number of cutting edges as much as possible choose thus minimizing the individual chip volumes and the engagement frequency be maximized. Moreover For the same reason, the circumferential speed must be designed to the maximum become.

Bei einem einteiligem Werkzeug ohne Mittenbohrung sind die Kräfte gegen die Zentrifugalkraft doppelt so hoch wie bei einem Werkzeug mit Aufnahmebohrung.With a one-piece tool without The center bore are the forces against the centrifugal force twice as high as with a tool with mounting hole.
