Abstract: During a positioning method for positioning a flat workpiece to be machined, in particular a sheet to be machined, for machining by means of a machining device, the workpiece is moved into a machining position by means of a controlled positioning drive with a positioning movement in a feed direction. During the positioning movement, the workpiece is supported on a workpiece support which, during the positioning movement of the workpiece, is moved, by means of a controlled support drive with a support movement in the feed direction. To avoid slippage between the workpiece and the workpiece support during the positioning movement of the workpiece, the support drive and the positioning drive are synchronized prior to the positioning movement of the workpiece by calibrating a control of the support drive and a control of the positioning drive.

Abstract: A method for monitoring a condition of a processed product produced from a plate-type starting workpiece including sheet metal, by separating the starting workpiece, as part of a continuous manufacturing process. An actual state of a parameter of the condition of the processed product is detected. The method includes detecting the condition of the processed product before separation of the starting workpiece. The actual state of the at least one parameter of the condition of the starting workpiece is detected on the starting workpiece before the separation thereof. A product-forming region of the starting workpiece which forms the processed product after the separation of the starting workpiece is assigned the actual state of the at least one parameter of the condition of the starting workpiece detected for the product-forming region as the actual state of the at least one parameter of the condition of the processed product.

Abstract: 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.

Abstract: An unloading method for unloading a machining product of a workpiece machining operation from a product support is provided. The method includes moving the machining product with a transfer movement along a transfer axis into an unloading region including a spatial unloading region limit located along the transfer axis and an unloading region length along the transfer axis which is larger than an actual product length of the machining product along the transfer axis; and continuing the unloading operation after the machining product has been provided for unloading. A reference length extends along the transfer axis and is at least the actual product length. After completion of the transfer movement, a distance along the transfer axis is compared with the limit distance from the reference point, and the unloading operation is continued only under a condition that the distance is less than the limit distance.

Abstract: An unloading method unloads a sheet metal machining product produced on a sheet metal working machine. The method includes: supplying the machining product to a supply device for unloading with a position and an orientation defined in a coordinate system of the supply device; moving an unloading member of the unloading device with a transfer movement into a transfer position on the machining product supplied to the supply device for unloading; calibrating, before the machining product is unloaded from the supply device, the numerical unloading control of the unloading device; and unloading the machining product from the supply device by the unloading device. The unloading of the machining product is controlled by the programmable numerical control which includes the programmable numerical unloading control of the unloading device and in which the coordinate system of the supply device and the similar coordinate system of the numerical unloading control are stored.

Abstract: A mechanical arrangement for processing a sheet-metal strip unwound from a coil has a separating device disposed between the coil and a processing device in a feed direction (5). When a comparison device determines that a current strip length with which the sheet metal-strip has passed the separating point in the direction of the processing device coincides with a defined processing length of the sheet metal-strip over which the sheet-metal strip is to be processed by the processing device, the separating device is actuated and the sheet-metal strip is thereby separated at the separating point.

Abstract: A method for shredding a scrap skeleton produced as a machining product of separating machining of a plate-like workpiece and having a scrap skeleton main plane is provided. The method includes creating an incomplete joint having a course along a separating line running in a longitudinal direction. The scrap skeleton is machined for separation along the separating line. A breakable residual connection arranged along the separating line is established between a first scrap skeleton part and a second scrap skeleton part. The method further includes, after the incomplete joint is created, deflecting the first scrap skeleton part and the second scrap skeleton part relative to one another perpendicularly to the scrap skeleton main plane so that the residual connection between the first scrap skeleton part and the second scrap skeleton part breaks, thereby separating the first scrap skeleton part and the second scrap skeleton part from one another.

Abstract: A method for processing a plastically deformable workpiece includes driving the workpiece using a workpiece drive so that the workpiece is moved to a feeding drive. driving the workpiece using a feeding drive so that a partial length of the workpiece is conveyed to a working region to be processed, driving the workpiece using the workpiece drive while the feeding drive has been stopped so that an intermediate length of the workpiece is arranged between the workpiece drive and the feeding drive. An advancement speed is adjusted such that the intermediate length is shorter than or equal to a maximum intermediate length. While the workpiece is being conveyed into the working region, a feeding speed of the workpiece generated by the feeding drive and the advancement speed generated by the workpiece drive are adjusted such that the intermediate length is shorter than or equal to the maximum intermediate length.
