Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zum bearbeitungssynchronen Messen eines Werkstücks in Werkzeugmaschinen. Während der Bearbeitung durch spanabhebende Prozesse, zum Beispiel Drehen und Fräsen, überwiegend rotationssymmetrischer Teile aber auch komplexer Teile mit rotationssymmetrischen und nicht rotationssymmetrischen Formelementen, soll gleichzeitig das Messen durchgeführt werden.The invention relates to a method and a device for the machining-synchronous measurement of a workpiece in machine tools. During machining by machining processes, for example turning and milling, predominantly rotationally symmetric parts but also complex parts with rotationally symmetric and non-rotationally symmetrical shaped elements, the measuring should be performed simultaneously.
Bei spanabhebenden Werkzeugmaschinen, die mit Werkzeugen mit bestimmter Schneide arbeiten, darunter werden Drehmaschinen, Fräsmaschinen und Dreh-Fräs-Bearbeitungszentren verstanden, wird bisher entweder bearbeitet oder gemessen. Beide Prozesse laufen nacheinander ab, wobei durch das Messen Korrekturwerte ermittelt und durch die Steuerung verarbeitet werden. Das nacheinander Messen ist in der Regel mit einem Tausch des Werkzeugs durch ein Messmittel verbunden. Andererseits ist das Messen außerhalb der Maschine mit einer speziellen Messeinrichtung bei Teilen höchster Präzision noch üblich. Für rotationssymmetrische Teile werden überwiegend Zweipunktmesssysteme eingesetzt. Aus dem Bereich Schleifmaschinen sind bearbeitungssynchrone Messungen mit tastenden Messeinrichtungen bei ständiger Anlage an dem rotierenden Werkstück bekannt. Diese können nicht ohne weiteres in den o. g. Werkzeugmaschinen, insbesondere Drehmaschinen, eingesetzt werden, da in diesen Maschinen andere Umgebungsbedingungen, hauptsächlich in Form größerer Spanvolumen und Verunreinigung herrschen.In the case of metal-cutting machine tools that work with tools with a specific cutting edge, which include lathes, milling machines and turning-milling machining centers, it has hitherto been either processed or measured. Both processes take place in succession, correction values being determined by the measurement and processed by the controller. The successive measurement is usually associated with an exchange of the tool by a measuring means. On the other hand, measuring outside the machine with a special measuring device is still common for parts of the highest precision. For rotationally symmetrical parts mainly two-point measuring systems are used. From the field of grinding machines machining-synchronous measurements with tactile measuring devices with constant contact with the rotating workpiece are known. These can not be readily in the o. G. Machine tools, especially lathes, are used, since in these machines other environmental conditions prevail, mainly in the form of larger chip volume and contamination.

Nachteilig ist bei den oben genannten technischen Lösungen, dass die Messung bei ruhenden Werkstücken hohe Nebenzeiten und einen höheren Energiebedarf der Maschine bedingt. Die Messungen erfolgen bei Werkzeugmaschinen nach der Bearbeitung, punktuell oder mit zwei Messflanken. Jeder Messpunkt muss angetastet oder ausgerichtet werden. An Schleifmaschinen werden vorwiegend berührende Messfühler eingesetzt, da die Werkstücke sauber gespült sind. Diese berührenden Messfühler können aufgrund des Späneanfalls bei der spanenden Bearbeitung und bei Trockenbearbeitung mit Werkzeugen mit bestimmter Schneide nicht eingesetzt werden.A disadvantage of the above-mentioned technical solutions that the measurement of stationary work high idle times and higher energy consumption of the machine requires. The measurements are made on machine tools after machining, punctually or with two measuring edges. Each measuring point must be touched or aligned. Grinding machines mainly use contacting probes because the workpieces are rinsed clean. These contacting probes can not be used due to chip buildup during machining and dry machining with tools with a specific cutting edge.
Aufgabe der Erfindung ist es, die Nachteile der o. g. Messeinrichtungen zu überwinden und ein Verfahren sowie eine Einrichtung zum gleichzeitigen Messen und Bearbeiten (spanabhebende Prozesse) in Werkzeugmaschinen zu entwickeln. Es ist ein kontinuierlicher Führungsvorgang Bearbeiten, Messen und Korrigieren zu realisieren. Die Messeinrichtung soll universell einsetzbar sein. Ziel ist es, die Bearbeitungszeit deutlich zu verkürzen, wodurch die Stückkosten gesenkt und die Qualität erhöht werden kann.The object of the invention is to overcome the disadvantages of o. G. To overcome measuring devices and to develop a method and a device for simultaneous measurement and machining (machining processes) in machine tools. It is a continuous leadership process to realize editing, measuring and correcting. The measuring device should be universally applicable. The goal is to significantly reduce processing time, which can reduce unit costs and improve quality.
Die Aufgabe wird gelöst, indem eine Lasermesseinrichtung auf einem separaten, zusätzlichen Schlitten angeordnet ist, der vorzugsweise gegenüber des Werkzeuges angeordnet ist und Verfahrwege in Xm-, Ym- und Zm-Richtung ermöglicht. Die Achse Ym kann wahlweise entsprechend der Messaufgabe angeordnet werden, wobei diese Achse insbesondere bei nicht rotationssymmetrischen Werkstücken benötigt wird, beispielsweise bei der Bearbeitung von Bohrungen, Sechskant und Gewinde.The object is achieved by a laser measuring device is arranged on a separate additional carriage, which is preferably arranged opposite the tool and allows travel paths in the Xm, Ym and Zm direction. The axis Ym can optionally be arranged according to the measurement task, this axis is needed in particular for non-rotationally symmetrical workpieces, for example in the machining of holes, hexagon and thread.
Die Messeinrichtung arbeitet berührungslos, mit Laser, kann aber auch mit einer tastenden Messeinrichtung bestückt sein. Durch die Bewegungen des Schlittens werden Messungen in axialer, tangentialer und radialer Richtung zum Werkstück möglich. Dieser Aufbau ermöglicht das Messen bearbeitungssynchron, d. h., während der Bearbeitung oder während der Nebenzeiten (Werkzeugwechsel).The measuring device works non-contact, with laser, but can also be equipped with a tactile measuring device. The movements of the carriage allow measurements in the axial, tangential and radial directions to the workpiece. This structure allows measuring synchronous machining, d. h., during processing or during non-productive times (tool change).
Die Messeinrichtung kann die Daten der Lasermessung auswerten und automatisch den Durchmesser und die Nachstellung des Werkzeuges berechnen. Die Messeinrichtung kann vorzugsweise als Laserdistanzsensor oder schaltender Laser ausgeführt sein. Der Laserdistanzsensor beinhaltet Sender, Empfänger und Auswerteeinheit. Gemessen wird direkt zur Oberfläche des Werkstücks. Die Messung erfolgt an einem Punkt bei drehendem Werkstück. Die Messeinrichtung ist nach der Werkstückmitte auszurichten oder einzustellen. Vorzugsweise erfolgt die Messung parallel zur X-Achse. Neben der Messung von Durchmessern können Radien, Unrundheiten und beliebige Formen gemessen werden.The measuring device can evaluate the laser measurement data and automatically calculate the diameter and adjustment of the tool. The measuring device can preferably be designed as a laser distance sensor or switching laser. The laser distance sensor includes transmitter, receiver and evaluation unit. It is measured directly to the surface of the workpiece. The measurement is made at one point while the workpiece is rotating. The measuring device must be aligned or adjusted to the center of the workpiece. Preferably, the measurement is parallel to the X-axis. In addition to the measurement of diameters, radii, irregularities and arbitrary shapes can be measured.
Die Anordnung der Messeinrichtung kann an frei beweglichen Schlitten, die unabhängig vom Bearbeitungsschlitten verfahrbar sind, erfolgen. Die Messeinrichtung kann auch direkt am Bearbeitungsschlitten angebracht werden. Bei Anordnung am Bearbeitungsschlitten kann jedoch nur in einem bestimmten Abstand vom Werkzeug an der bearbeiteten Fläche gemessen werden. Unter Nutzung an der Maschine vorhandener Vorschubeinrichtungen kann die Messeinrichtung bzw. der Laserdistanzsensor auch auf einem Lünettenschlitten, der bereits über eine Z-Achse verfügt, mit den zusätzlichen Messachsen in Xm bzw. Ym angebracht werden. The arrangement of the measuring device can be carried out on freely movable carriages, which can be moved independently of the machining carriage. The measuring device can also be attached directly to the processing carriage. When placed on the machining carriage, however, it is only possible to measure at a certain distance from the tool on the machined surface. By using feed devices provided on the machine, the measuring device or the laser distance sensor can also be mounted on a steady rest slide, which already has a Z axis, with the additional measuring axes in Xm or Ym.
Die Messeinrichtung sollte vorzugsweise gegenüber der Zerspanungsstelle oder an beliebigen Punkten im Arbeitsraum der Werkzeugmaschine installiert werden. Weiterhin kann die Anbringung an vorhandenen Aggregaten oder Vorschubeinheiten integriert oder als separate Einheit erfolgen. Vorteilhaft ist die der Zerspanungsstelle gegenüberliegende Anordnung des Messschlittens, so dass weitestgehend ohne eine Beeinflussung durch Späne während der Bearbeitung beliebig gemessen werden kann. Vorzugsweise sollten genaue Führungssysteme an der Werkzeugmaschine für die Bearbeitungs- und Messschlitten eingesetzt werden.The measuring device should preferably be installed opposite the cutting point or at any point in the working space of the machine tool. Furthermore, the attachment to existing units or feed units integrated or carried out as a separate unit. Advantageously, the cutting point opposite arrangement of the measuring slide, so that as far as possible without interference from chips during processing can be measured. Preferably, accurate guide systems should be used on the machine tool for the machining and measuring carriages.
Mit der Lasermesseinrichtung können verschiedenartige geometrische Punkte, z. B. Absätze oder Flanken gemessen und damit Abstände bzw. Längen am Werkstück ermittelt werden.With the laser measuring device various geometric points, z. B. heels or flanks measured and thus distances or lengths are determined on the workpiece.
Die Lösung der Aufgabe umfasst weiterhin eine maschinentaugliche Laserschranke, die einen Punkt an den jeweiligen Messstellen (zum Beispiel Passungen) fixiert und danach mittels einer Hubvorrichtung die Tangente an der Werkstückoberfläche der zu bearbeitenden Passungen prozessintern erfasst. Die Messung erfolgt damit tangential zur Werkstückoberfläche mit einem so genannten Unterbrechungslaser. Die Messung kann bei ruhendem oder auch drehendem Werkstück erfolgen.The solution to the problem further comprises a machine-suitable laser barrier, which fixes a point at the respective measuring points (for example, fits) and then detects the tangent to the workpiece surface of the fits to be machined by means of a lifting device in-process. The measurement is thus tangential to the workpiece surface with a so-called interruption laser. The measurement can be done with stationary or rotating workpiece.
Durch Verfahren der Messeinrichtung, des Laserdistanzsensors, in Richtung Y-Achse mittels Hubeinrichtung, wird ausgehend vom Werkstückmittelpunkt bis zur Tangente der Werkstückoberfläche gemessen. Diese Messeinrichtung besteht aus einem Messschlitten mit einer Längenmesseinrichtung, Hubeinrichtung und Laserdistanzsensor. Die Messung erfolgt nur in einer Richtung. Der Laserdistanzsensor ermöglicht die Realisierung einer sehr hohen Messgenauigkeit. Weiterhin kann neben rotationssymmetrischen Werkstücken jede erreichbare Kontur eines Werkstückes vermessen werden, beispielsweise Gewindegänge, hergestellt mit Abwälzfräsen, gefräste Flächen und Bohrungen.By moving the measuring device, the laser distance sensor, in the direction of the Y-axis by means of a lifting device, starting from the workpiece center point to the tangent of the workpiece surface is measured. This measuring device consists of a measuring slide with a length measuring device, lifting device and laser distance sensor. The measurement only takes place in one direction. The laser distance sensor enables the realization of a very high measuring accuracy. Furthermore, in addition to rotationally symmetrical workpieces any achievable contour of a workpiece can be measured, for example, threads, manufactured with hobbing, milled surfaces and holes.
Die Werkzeugmaschine hat eine Steuerung oder einen zusätzlichen Messrechner für die Auswertung der Messdaten. Die erforderliche Software berechnet den Werkstückdurchmesser. Die Messung ermöglicht prozessintern eine genaue Bestimmung der realen Werkstückdurchmesser. Mit einer geeigneten Software wird die Rückkopplung zum Prozess des Werkzeuges zum Ausgleichen des Schneidkantenrückversatzes eingeleitet.The machine tool has a controller or an additional measuring computer for the evaluation of the measured data. The required software calculates the workpiece diameter. The measurement allows in-process determination of the actual workpiece diameter. With appropriate software, the feedback to the process of the tool for compensating the cutting edge return offset is initiated.
Die Werkzeugmaschine kann weiter ausgestaltet werden, beispielsweise durch Anordnung einer Späneabblaseinrichtung und/oder einer Reinigungseinrichtung.The machine tool can be further configured, for example by arranging a chip blower and / or a cleaning device.
