Abstract: An ultrasonic cutter cuts edge chamfers of plate-shaped workpieces using a cutter head which forms an axis of rotation and a blade which extends from the cutter head and forms a cutting wedge, terminating in a straight cutting edge, between flank and contact faces determined by the wedge angle. In order to create advantageous structural conditions, the axis of rotation extending on the blade side of the flank face is at a distance from the flank face which is equal to or greater than the distance of the center of mass of the blade from the flank face and the cutting edge, extending in the direction of the axis of rotation, extends at a distance from the axis of rotation which corresponds at most to the blade thickness.

Abstract: The invention relates to a ultrasonic cutter for the cutting of edge chamfers of plate-shaped workpieces, having a cutter head (1) which forms an axis of rotation (6) and having a blade (2), which extends from the cutter head (1) and forms a cutting wedge, terminating in a straight cutting edge (5), between flank and contact faces (3, 4) determined by the wedge angle. In order to create advantageous structural conditions, it is proposed that the axis of rotation (6) extending on the blade side of the flank face (3) is at a distance (e) from the flank face (3) which is equal to or greater than the distance (s) of the centre of mass (S) of the blade (2) from the flank face (3), and that the cutting edge (5) extending in the direction of the axis of rotation (6) extends at a distance (a) from the axis of rotation (6) which corresponds at most to the blade thickness (d).

Abstract: A chucking apparatus for a workpiece with honeycomb structure includes a table that can be supplied with vacuum and a clamping plate which can be placed on the table and which accommodates the workpiece in the region of an already profiled surface determined by the face ends of the honeycombs, whose receiving surface, which corresponds to the profiled surface of the workpiece, is provided with suction openings to the table. In order to provide advantageous chucking conditions, the clamping plate has an open-cell structure.

Abstract: A method is described for producing a blank (1) from a fiber layup (5) having an edge (3) forming a chamfer (2), wherein the fiber layup (5), which is suctioned onto a cutting support (6) of a cutting table (7), is cut through using a contour cut (17), which extends into the cutting support (6), along the intended contour (4) of the blank (1) and is provided with the chamfer (2) using a chamfer cut (16) running at a flat chamfer angle (?) along the intended contour (4).

Abstract: An apparatus is for detaching a workpiece from a cutting table. The workpiece is a cutting cut out from a flexible web made of fiber material. A raising device is displaceable relative to the cutting table receiving the web with the cutting and has a run-up surface for the workpiece ascending from the cutting table for progressively lifting the workpiece from the cutting table. A receiving device progressively receives the workpiece after the run-up surface. A lifting device is provided at a distance above the cutting table and includes a receiver which can be adjusted to the length of the boundary section of the cutting facing the raising device and which holds the received boundary section in a transfer position lifted off from the cutting table. The raising device is displaceable between the lifting device and the web resting on the cutting table.

Abstract: An apparatus is described for detaching a workpiece from a cutting table (1), which workpiece comprises a cutting (6) cut out from a flexible web (10) made of fiber material, comprising a raising device (4) which is displaceable relative to the cutting table (1) receiving the web (10) with the cutting (6) and which comprises a run-up surface (8) for the workpiece ascending from the cutting table (1) for progressively lifting the workpiece from the cutting table (1), a receiving device (7) progressively receiving the workpiece after the run-up surface (8) and a lifting device (14) for the edge of the workpiece facing the raising device (4).

Abstract: A device is described for cutting soft, flexible sheet-like workpieces (1) which has a work support (2), a cutter head (3) which can be positioned against the work support (2) and has at least one cutter (4), and a device for holding down the workpiece (1) to operate in conjunction with the cutter head (3), whereby provision is made for said device to be located laterally adjacent to the cutter (4) and whereby said device can be adjusted in relation to said cutter perpendicular to the work support (2). In order to achieve advantageous construction conditions it is proposed that the hold-down device consists of at least one pressure roller (5) which forms a conical roller surface (18) and which has a trunnion (6) extending transversely in relation to the direction of cut and inclined at an angle to the work support (2).

Abstract: To produce a chamfer or a keyway on a workpiece, the workpiece is machined with a longitudinal feed following the course of the chamfer or groove. To obtain a clean chamfer or groove in an economic way, machining is effected by a peeling operation by means of a peeling knife, whose broadside forming a cutting edge is aligned transverse to the feed direction during the longitudinal feed, and which is guided parallel to the workpiece surface with a certain cutting depth.
