A changeover apparatus for changing between workpiece supports for a machining machine. The changeover apparatus has a base frame with a carrier apparatus for the workpiece supports, which are vertically movable by the carrier apparatus, with the result that one of the workpiece supports can be transferred into a working plane in which the workpiece support is moved from the carrier apparatus into the machining machine and guided out therefrom. A lifting apparatus acts between the base frame and the carrier apparatus and by way of which the carrier apparatus can be vertically moved relative to the base frame for one workpiece support to take up a first lifting position or a further lifting position in the working plane. The lifting apparatus contains a slotted guide, which movably actuates the carrier apparatus with the workpiece supports together between the first lifting position and the further lifting position.

A reflected beam detection value obtained by detecting a reflected beam of a visible beam generated on a sheet metal or a scattered beam detection value obtained by detecting a scattered beam from an optical component is stored in a storage unit, the reflected beam or the scattered beam being detected at a time when the sheet metal is cut by irradiating the sheet metal with a laser beam under a predetermined processing condition. The reflected beam detection value or the scattered beam detection value stored in the storage unit is registered as a reference value associated with the predetermined processing condition.

Disclosed is a bridge and body embodiment used in laser cutting machines. The embodiment has two bodies located facing each other and extending along at least a first guide component on an inner surface longitudinally, a bridge moving back and forth on the first guide component by at least one second guide component connected in between the bodies in perpendicular form and connected onto both side surfaces, a first driving component located on both side surface of the bridge or the inner surface of the body providing moving of the bridge, and a second driving component located on the body inner surface and providing movement of the first driving component on the inner surface of the body.

A method for laser cutting a workpiece includes the steps of guiding a laser beam over the workpiece in a cutting direction so as to produce a cutting kerf with two cutting flanks and melting material on the workpiece at a cutting front that extends between the cutting flanks and adjoins at least one of the cutting flanks at an angle. The laser beam has a non-circular cross section and, at a front of the laser beam in the cutting direction, a continuous cutting beam contour corresponding to the cutting front.

A processing system includes: a processing apparatus for processing an object; a rotation apparatus for rotating a holding part holding the object; a movement apparatus for moving at least one of the processing apparatus and the holding part; a measurement apparatus for measuring at least a part of the object held by the holding part; and a control apparatus for controlling the movement apparatus and the rotation apparatus based on a measured result by the measurement apparatus to rotate the holding part and to move at least one of the processing apparatus and the holding part

A decoating method for the edge decoating of glass sheets, the glass sheets having at least on one of their two glass surfaces a protective coating in the form of a peel-off protective film or in the form of a polymer protective layer that cannot be peeled off, and preferably having a functional coating situated under the protective coating, the protective film being partially mechanically removed, in particular ground away, for the edge decoating, in the form of at least one film strip, laser traces being introduced into the protective film before the mechanical removal of the film strip, and the laser traces being introduced in such a way that the film strip is removed in the form of individual film strip partial pieces separated from one another by the laser traces; or the polymer protective layer being removed using laser radiation.

A welding system comprises a welding module and a moving module adapted to move the welding module to a predetermined welding position. The welding module includes a guiding device and a welding tool. The guiding device has a plurality of tubular guiding heads arranged in a row, ends of the plurality of tubular guiding heads are disposed close to joints of a plurality of cables so as to guide a plurality of welding wires to the joints of the plurality of cables.

A machine frame for a machine tool is disclosed having two longitudinal members running in a first direction and two transverse members connecting the longitudinal members and running in a second direction running transversely to the first direction, wherein the longitudinal members and transverse members define a machining space for the machine tool (200), at least two, preferably at least four, first floor fastening units for the predominant transmission of forces in the first direction into a foundation, wherein the first floor fastening units are fastened to ends of the longitudinal members, and at least two second floor fastening units for the predominant transmission of forces in the second direction into a foundation, wherein the second floor fastening units are fastened to at least one of the longitudinal members in its central region, wherein one, preferably exactly one, longitudinal member with the second floor fastening units has a cross-sectional geometry for the predominant force transfer in the second direction.

A display processing mask manufacturing apparatus includes a stage, a clamp arranged outside the stage, and a chuck configured to move in a direction and arranged above the stage. The clamp includes a first clamp and a second clamp spaced apart from the first clamp in a first direction and arranged at a position opposite to a position of the first clamp with respect to the stage, and the chuck includes a first chuck and a second chuck spaced apart from the first chuck in a second direction crossing the first direction.

A computer-implemented method is provided for shaping an edge of a part to be cut from a workpiece using a material processing system comprising a processing head configured to deliver a processing stream. The method includes calculating a start point and an end point of a shaping path proximate to the edge of the part based on a desired edge profile and determining a set of operating parameters to controllably impinge the processing stream about the edge of the part to execute the shaping path from the start point to the end point. The method further includes positioning the processing head normal to a surface of the part and controllably impinging the processing stream at the edge of the part, by the processing head, to shape the desired edge profile.
