摘要： The control system is provided in a grinding machine composed of an axially movable rotational shaft having a grinding tool and being supported magnetically by electromagnets. The control system includes a target position modifying controller for modifying or shifting a reference target levitating position of the rotational shaft in a retreating direction away from a workpiece reaches a predetermined amount. The control system further includes a rigidity modifying controller operative during quick feed operation of the rotational shaft for making a rigidity of the rotational shaft lower than that in the grinding operation by adjusting exciting currents of the electromagnets. The control system still further includes a dressing controller operative during dressing of a new grinding tool for detecting that the grinding tool begins to touch a dresser and for judging that the dressing is completed just when an arithmetic value calculated based on the detection reaches a predetermined value.

摘要： An improved multi-axis gas bearing stage assembly is disclosed which has a base (16), an intermediate stage element (24), a stage (11), and a control system for controlling the movement of the intermediate stage element and the stage. The control system includes first and second Y-axes positioning sub-systems for differentially positioning first and second ends of the intermediate stage element (24) along first and second Y-axes of motion, with respect to the base. and an X.-axis positioning sub-system (98) for positioning the stage along an X i -axis of motion, with respect to the intermediate stage element (24). The positioning sub-systems comprise linear motors (84,86,98), measuring scales (102,104, 106), and read heads (108,110,112). A method of achieving orthogonality between the Y- and X i -axes that features on orthogonality alignment standard is as well disclosed.

摘要： A self-propelled robot consists of a platform (24a) with a plurality of castors (26a) to support the platform on and space the platform from a supporting surface, as well as permitting any selected direction of movement over the support surface. The magnetic field generating means (20a to 23a) of at least two linear motors are arranged on the platform transversely to one another and generally parallel to the support surface and so that their flux links with the support surface or a magnetic backing thereof. The motor fluxes linking the supporting surface drive the platform. The platform is provided with tool support means (46) and that tool support means includes articulation structure (42a) with associated drive means (44a) which permits tool positoning. As a consequence, the robot platform (24a) may be moved over the surface in a predetermined pattern doing work with a supported tool or it may be moved from point to point where work is to be done where the tool is actuated either manually or by programmed information. If the support surface is magnetic, the surface need not be horizontal to hold the platform.

摘要： Es wird eine Positioniereinrichtung in Portalbauweise beschrieben, mit zwei parallelen Linearführungen (FX1, FX2) mit integrierten Linearantrieben, die je einen X-Laufwagen (LX1, LX2) in einer X-Richtung beweglich halten, sowie mit einem mit den beiden X-Laufwagen (LX1, LX2) verbundenen Querbalken (FY), der mittels eines integrierten Linearantriebs einen Laufwagen (LY) in einer zur X-Richtung senkrechten Y-Richtung beweglich hält. Die Positioniereinrichtung weist außerdem einen Werkzeughalter (1), auf, der am Y-Laufwagen (LY) in einer Z-Richtung geführt ist und ein Werkzeug (2) zur Bearbeitung eines in einer X-Y-Ebene angeordneten Werkstücks trägt, wobei das Werkzeug (2) in X-Richtung versetzt neben dem Querbalken (FY) angeordnet ist. Ein in Z-Richtung oberhalb des Werkzeugs (2) angeordneter Kraftrahmen (3) überträgt eine auf das Werkzeug (2) wirkende Prozesskraft (F) auf die Laufwagen LX1, LX2, ohne den Querbalken (FY) mit einem Drehmoment zu verformen. Die Prozesskraft (F) wird von einem Elektromagnet (7) aufgebracht, der zwischen dem Kraftrahmen (3) und dem Werkzeughalter (1) wirkt.
