摘要： An einer Werkzeugmaschine ist an der Spindellagerung eine dynamische Spindelverstellung vorgesehen, die eine Verstellbewegung zur Kompensation eines Taumelschlags des von der Arbeitsspindel gehaltenen Körpers gestattet. Die Regelung ist mindestens so dynamisch ausgelegt, dass die Regelung ein sicheres Nachführen der rotierenden Arbeitsspindel ermöglicht. Dadurch können ein oder mehrere Spindeln relativ zu einem fixen Maschinenkörper derart bewegt werden, dass die Bahn eines an der Arbeitsspindel gehaltenen Körpers eine ideale Rotation um die gewünschte Körperachse (Symmetrieachse) ist. Die Kompensationsbewegung kann durch Beaufschlagung entsprechender Aktoren der Lagereinrichtung mit sinus- und cosinusförmigen Stellsignalen erreicht werden, die sich zu einer Kreisbewegung der betreffenden Lagereinrichtung überlagern. Diese Kreisbewegung kompensiert Orbitalbewegungen des fehlausgerichteten, an der Arbeitsspindel gehaltenen Körpers (7).

摘要： The invention relates to a grinding machine tool comprising a machine control device which initially determines the wobbling of a blank (7) in relation to the ideal receiving axis (C) of tool receiving element by means of a suitable measuring device comprising, for example, a sensor (9) and a measuring module. When the blank (7) and/or tool are ground, said wobbling is taken into account and compensated, i.e. the grinding tools track a wobbling tool such that the tool is machined true to size and in a concentric manner.

摘要： Bei einer Werkzeugschleifmaschine 1 ist zur Überwachung der Prozeßführung eine Messeinrichtung 17 vorgesehen, die vorzugsweise als kombiniertes Durchlicht-Auflichtmesssystem ausgebildt ist. Dieses ermöglicht sowohl die präzise Erfassung von Kanten, bspw. Schneidkanten im Streit- oder Durchlichtmessverfahren, als auch die Vermessung von Flächen und Vertiefungen im Auflichtverfahren. Die automatische Kontrollmessung mittels dieses Messsystems 17 gestattet es der angeschlossenen Steuereinrichtung 15, die Prozeßparameter für den Schleifvorgang automatisch nachzustellen, so dass Maßänderungen infolge von Temperaturdrift, mechanischen Ungenauigkeiten der Mechanik der Schleifmaschine oder Schleifscheibenverschleiß automatisch ausgeglichen werden. Dies ermöglicht eine Fertigung von größeren Losen innerhalb sehr enger Toleranzen und mit hoher Präzision.

摘要： A method is described for grinding a composite workpiece (18) to form a component having concentric (31) and eccentric cylindrical regions (30). The method comprises mounting the workpiece (18) in a computer controlled grinding machine (10) having a grinding wheel (12) the advance and withdrawal of which is controllable by a programme entered into the controlling computer (32), loading a wheelfeed controlling programme into the computer, relatively positioning the grinding wheel and the workpiece to align the wheel with a first selected region of the workpiece, advancing the grinding wheel towards the selected region so as to grind the surface thereof, controlling the wheelfeed so as to maintain grinding contact between the grinding wheel and the workpiece so as either to grind a concentric cylindrical region thereon or an eccentric (offset) cylindrical region thereon as required, information about each selected region of the workpiece being stored in the computer and addressed as appropriate so that the wheelfeed can be cotrolled appropriately depending on whether a selected workpiece region is to be ground as a concentric or an eccentric (offset) cylindrical region. The method allows a workpiece having both concentric and eccentric (offset) cylindrical regions thereon to be ground using a single grinding machine under computer control without demounting the workpiece from the machine. The method also envisages introducing small advance and retract movements in the wheelfeed whilst the grinding wheel is engaged in grinding a concentric cylindrical workpiece region so as to introduce into the ground region an eccentricity which is equal and opposite to any eccentricity which grinding process forces introduce into the ground region, so that the two eccentricities cancel out. A computer controlled grinding machine is described as are programmes for controlling the machine.

摘要： The aim of the process and associated device is a substantially more accurate correction of dynamic misalignments caused unavoidably by vibrations in the machine than is possible with known processes. In the process, the disturbances which directly determine the misalignments at the point of action between tool and workpiece are determined. A mathematical process model is generated from the disturbances and used to generate the non-statistical components of the disturbances. On the basis of the process model, a preliminary estimate is formulated of the future behaviour of the disturbance at the point of action and this is then used to correct the misalignment. The process can be used with machine tools to improve surface finish.

摘要： An optical memory disk has a recording layer which is disposed on one surface of a plain circular support base and has a plurality of radially spaced data tracks for storing data items therein, the data tracks being grouped into a number of data track groups. Each of the tracks is divided into a plurality of angularly consecutive sectors bearing a plurality of angularly equally spaced sector marks, respectively, the sector marks on the tracks of each of the data track groups being located in angularly different positions, respectively. There are also disclosed a method of and a system for rapidly and reliably accessing a desired target track among the data tracks on the optical memory disk.

摘要： An automatic dynamic error compensator for compensating the position error arising within a servo drive system includes a measuring head which is operative to measure the relative indicated position of two or more measuring vanes on the movable member. The measuring head, together with a feedback transducer, that measures indicated movable member position, are coupled to a feedback system. The feedback system determines the indicated movable member position from the feedback transducer reading and then compares the indicated movable member position to the known vane position upon occurrence of a vane crossing to yield a compensating value.
