    摘要: An arrangement is used for the efficient mass production of individual bodies for the artificial rebuilding of teeth, for example. The arrangement comprises a first pair of co-rotating elements, of which the first element (1) is so arranged as to support a replica (21) of a body which is to be produced, and the second element (2) is so arranged as to support a blank from which the body is to be produced. The replica and the blank are caused to rotate synchronously about the axis of rotation (3, 4) of the respective element. In a second pair of elements a third element supports a sensing device (31) which is capable of interacting with the external contour of the replica, and a fourth element supports a tool (52) by means of which the blank is capable of being machined. The first and second pairs of elements are capable of being displaced relative to one another. The fourth element is adjustably connected to the third element (29) in such a way that the tool executes movements which correspond to the shape of the external contour of the replica sensed by the sensing device (31).

    摘要: An apparatus for use with an hydraulic tracing system on a machine tool having a slide controlled by the deflection of a tracing stylus wherein there is provided a means for limiting the penetration of a cutting tool into a workpiece. The apparatus comprises means in series with a tracer control valve for shutting off fluid flow to the slide when the cutter has reached a preset penetration level and means for resetting this level.

    摘要: Apparatus and a process for correcting the position of a movable machine element which is positionally controlled by a permanentcirculation hydraulic servomotor copying-control system. Means are provided for measuring the positional error of the element and varying the rate of the liquid supplied to the hydraulic servomotor as a function of the positional error.
