An augmented reality display device is formed to superimpose a real image of the workpiece support or of a part thereof with information on a specifiable target position and/or target machining contour of the workpiece and/or on a specifiable target position of the clamping means. The augmented reality display device can be worn on the body by a user, who positions the workpiece and/or clamping means on the workpiece support at least partially manually. ## Claims ### Claim 1 An assembly comprising a CNC machining center configured to machine a workpiece; a workpiece support; a clamp to be positioned on the workpiece support at least partially manually, for securing the workpiece to the workpiece support; and an augmented reality display device configured to superimpose a real image of the workpiece support or of a part of the workpiece support with information on: a specifiable target position of the workpiece; and/or a target machining contour of the workpiece, and/or a specifiable target position of the clamp, and wherein the augmented reality display device is configured to be worn on the body by a user, the user positioning the at least one workpiece and/or the clamp on the workpiece support at least partially manually using the information superimposed on the real image by the augmented reality display device. ### Claim 2 (depends on 1) The assembly according to claim 1, wherein the at least one augmented reality display device is arrangeable between the workpiece support and an eye of the user. ### Claim 3 (depends on 2) The assembly according to claim 2, wherein the augmented reality display device is glasses. ### Claim 4 (depends on 1) The assembly according to claim 1, wherein the augmented reality display device has: a camera for acquiring the real image of the workpiece support or of a part thereof, and/or a display screen configured to display a representation of the virtual image comprising information on the target positions and/or target machining contours of the workpieces and/or on the target positions of the clamp, and preferably of the real image of the at least one workpiece support or of a part thereof. ### Claim 5 (depends on 4) The assembly according to claim 4, wherein the display screen is further configured to display the real image of the workpiece support or of a part thereof. ### Claim 6 (depends on 1) The assembly according to claim 1, wherein the augmented reality display device includes a position marker. ### Claim 7 (depends on 6) The assembly according to claim 6, wherein the position marker is arranged on the workpiece support and/or on the clamp. ### Claim 8 (depends on 1) The assembly according to claim 1, wherein the augmented reality display device includes a camera for acquiring image data of the real image of the at least one workpiece support or of a part thereof such that an actual position of the workpiece support and/or an actual position of the clamping means and/or an actual position of the workpiece can be determined from the image data. ### Claim 9 (depends on 1) The assembly according to claim 1, wherein the virtual image comprises: information on the degree of overlap between an actual position of the clamp and the target position of the clamp, and/or information on the degree of overlap between an actual position of a workpiece and the target position of the workpiece. ### Claim 10 (depends on 1) The assembly according to claim 1, wherein the information on the specifiable target position of the clamp can be calculated from information on the machining of the workpiece. ### Claim 11 (depends on 1) The assembly according to claim 1, further
