A method for operating a plant, including providing a number of pallets required for a production process for a pallet storage unit and transferring the pallets between a production position and a storage position. The pallets are stored in the storage position on supports of storage locations in each case and define the storage height of a respective storage location. The method includes configuring a storage unit by the pallets adapted to the production process carried out on a mechanical production device. A new configuration of the storage unit is carried out. A pallet supply is provided to which pallets are transferred that are required for an existing configuration and not required for a new configuration, and/or from which pallets stored in the pallet supply are removed that are required for the new configuration in addition to the pallets required for the existing configuration.

A method for replacing a set of parameters, the method including producing a cutting edge with a laser cutting machine using a set of parameters. The cutting edge has a machining error. The machining error is classified according to a type. Several modified sets of parameters are generated based on the classification. Further cutting edges are produced using the modified sets of parameters. Each modified set of parameters is used to produce one further cutting edge. The method includes creating an evaluation of the further cutting edges by rating an occurrence of machining errors for each, ascertaining which of the further cutting edges was evaluated as best, and replacing the set of parameters with the optimized set of parameters. The optimized set of parameters is based on the modified set of parameters with which the ascertained further cutting edge that was evaluated as best was produced.

A method and machine for cutting and removing a workpiece part from a plate-shaped material includes cutting the workpiece part with a beam or jet directed onto the material and separating the workpiece part and material. The workpiece part is removed as a scrap skeleton removal part. The cut-free workpiece part is lifted out of a workpiece supporting plane by a lifting device and removed by a gripping device, or the cut-free workpiece part is removed downwards from the plane through a gap between workpiece supporting surfaces by an ejection device, or gravity removes the cut-free workpiece part downwards through the gap. Before cutting the workpiece part free, a sacrificial part adjoining the workpiece part and partially having a common cutting line with the workpiece part is cut free from the material before cutting the workpiece part free in the material or scrap skeleton.

A device for releasing a workpiece with a cut edge, produced by a first machine tool, for a processing process, the device including a detector for detecting a formation of the cut edge and a controller which is configured to release or not release the workpiece for the processing process based on the detected formation of the cut edge. A method for operating the device includes detecting the formation of the cut edge and releasing or not releasing the workpiece for the processing process based on the detected formation of the cut edge.

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.

A method for determining a minimum width of a microjoint by which, when machining a workpiece, in particular a sheet-like workpiece, a workpiece part remains connected to a remaining workpiece of the workpiece. In the method, the minimum width of the microjoint is determined in dependence on at least one machining parameter which influences a relative position of the workpiece part in relation to the remaining workpiece during the machining of the workpiece. A further method determines an attachment position of such a microjoint and a still further method machines the workpiece.

A method for arranging error reports into at least two error report groups of different error situations, the method including reading in error reports each with at least two error report attachments of different domains and determining a similarity operator for at least two of the different domains to determine a similarity between error report attachments of the same domain. The method also includes determining similarity values of the error report attachments of the same domain by comparing individual error report attachments of the same domain from different error reports by the determined similarity operator. The method also includes grouping the error reports into the at least two error report groups of different error situations based on the determined similarity values.

A handling device for removing a residual grid assembly from a workpiece support in a machine tool, the residual grid assembly being configured to be produced from a plate-shaped material by a cutting process and including at least one workpiece and a residual grid which are arranged in a common workpiece plane after machining, the handling device including a support framework, a rear-engagement device, and a holding down element. The rear-engagement device has rear-engagement elements which can be moved relative to the support framework and, in an engagement position, jointly engage behind the at least one workpiece and the residual grid. The holding-down element is provided on the support framework. The holding-down element is provided between the support framework and the rear-engagement elements arranged in the engagement position. The residual grid assembly is configured to be clamped in position between the holding-down element and the rear-engagement elements.

A handling device for separating a workpiece from a residual grid of an assembly of parts, which can be produced from a plate-shaped material by a cutting process, the handling device including a support framework on which a rear-engagement device is provided which has rear-engagement elements configured to moved relative to the support framework from a disengagement position into a gripping position in which the assembly of parts is engaged from behind. The handling device includes a holder arranged on the support framework and including at least one holding element, by which the assembly of parts is configured to be transferred from the gripping position into a separating position in which the assembly of parts is lifted away from the rear-engagement elements. The assembly of parts in the separating position is subjected to vibrations to separate the at least one workpiece from the residual grid.

A method for separating at least one workpiece from a residual grid of a residual grid assembly of parts which is produced from a plate-shaped material by a cutting process, the method including feeding the residual grid assembly of parts to a holder of a separating device together with a holding-down element resting on an upper side of the residual grid assembly of parts. The method further includes jointly exciting and thereby vibrating the holding-down element and the residual grid assembly of parts by a vibration drive. The holding-down element is configured to enable the at least one workpiece to be separated in a targeted manner only downward with respect to a bottom side of the residual grid assembly of parts.
