Abstract: The present invention relates to a machine tool and a corresponding process for machining a workpiece by means of one or more tools controlled by means of control data, the machine tool comprising at least 5 simultaneously controllable axes. A control device being suited to control the tool supported in a support means by means of the control data along a tool path to remove material from the workpiece clamped in a clamping means. The machine tool being suited to machine a first workpiece to provide the first workpiece with a first gearing, the first workpiece being a counter piece to a second workpiece having a second gearing.

Abstract: In a method for engraving a printing cylinder using an engraving member in an electronic engraving machine, an engraving tool of an engraving member controlled by an engraving signal engraves a sequence of grooves arranged in a printing screen in a rotating printing cylinder. The engraving signal is formed by superimposing an image signal representing the shade values of light and dark of the grooves to be engraved and a periodic screen signal for generating the printing screen. In order to compensate for disruptive influences on the shade values of the engraved grooves resulting from operating temperatures in the engraving member, the operating temperature in the engraving member is measured at at least one measurement point. Depending on at least one measuring temperature, the electrical control of the engraving member is corrected and/or the temperature of at least one component of the engraving member and/or the air circulating around the engraving member is modified.

Abstract: Apparatus for scribe engraving a workpiece with a miniature representation of a two-dimensional pattern in response to movement of a stylus following the pattern includes a spherically rotatable member having a frusto-spherical surface rotatably retained within a frusto-spherical bearing race remote from the pattern and having a passageway therethrough axially skew to the pattern, where the scribe extends fixedly from the spherically rotatable member for movement unitarily with the rotatable member, including means for connecting the rotatable member with the stylus so that the rotatable member rotates in response to stylus movement following the pattern where the connecting means is selectably disengageable from the rotatable member.

Abstract: Apparatus for scribe engraving a workpiece with a two dimensional miniature representation of a pattern followed by a stylus includes a stylus moveable within a two dimensional pattern, a base supporting the pattern, a sleeve receiving the stylus and extending upwardly therefrom with the stylus protruding from the sleeve, a spring biasing the stylus outwardly of the sleeve, a beam above the base including a bearing seat, a spherically rotatable pivot member residing on the bearing seat, a scribe connected to the pivot member and moving unitarily with the pivot member and a tube telescopingly connecting the sleeve with the pivot member for rotation of the pivot member in the seat in response to movement of the stylus following the pattern.

Abstract: Apparatus for engraving has a work piece support adjacent to scribing means for engraving inidicia on the work piece. A stylus moves a pivotal support to which scribing means is attached. Front-writing is achieved by positioning the scribing means above the stylus but below the pivot of the pivotal support. Scribing means concurrently engrave a plurality of work pieces from a single stylus. The work piece support is movable up and down, towards and away from the scribing means. The distance between the pivotal support and the stylus is adjustable. Vibratory means connected to the pivotal support vibrate the scribing means when the scribing means contacts the work piece. Identification means for dentures is provided.
