In some aspects of the invention, tool components for processing of plate-like workpieces, the tool component include an end face adjoined by a tool region provided for regrinding, the tool region being configured to undergo regrinding as a result of wear; and at least one identification mark located on the tool component to indicate the amount of shortening of the tool region as a result of regrinding.

Tool components and related machines and methods

A tool system is provided that has a stamp or punch adapter including eccentrically positioned stamp receptacles. This system permits a simple exchange of tool inserts in the stamp adapter. These tool inserts are also usable in another tool system. The system also permits combining the stamp adapter with a stamp shaft, which can also be used in another tool system. These features permit stamping (and punching) with minimal tooling and retooling efforts.

Tool system with interchangeable tool inserts for punching machines

A method of discharging workpieces cut from a planar material on a processing machine. A workpiece discharge device has several holding elements to receive and carry respective workpieces. After receiving a cut workpiece, the discharge device is moved to a waiting position outside and adjacent a processing region of the machine, and may then be moved back into the processing region to receive a subsequently cut workpiece before being moved to an unloading station.

Discharging workpieces

Machine tools for processing plate-like workpieces by punching include a punching tool including a punch and a punching die, a drive unit for moving the punch and the punching die relative to each other along a stroke axis for cutting a workpiece part free from a plate-like workpiece, a hold-down device that is movable along the stroke axis and that includes a stripper that contacts an upper surface of the plate-like workpiece while the plate-like workpiece is punched through by the punch, a detection device for detecting a reference position of the hold-down device along the stroke axis, wherein the stripper contacts the upper surface of the workpiece at the reference position, and a numerical control unit for positioning the stripper at a particular distance from the reference position such that a workpiece part that has been cut off can be moved away from a processing region.

Moving workpiece parts on machine tools

In some aspects of the invention, a punching tool includes a punching stamp including a stamp shaft and an axial stop; and an adjustment ring having a center opening configured to receive the stamp shaft and abut the axial stop, where a first mark is located along a cylindrical portion of the stamp shaft adjoining the axial stop, and at least a portion of the first mark remains visible when the adjustment ring is abutted against the axial stop.

Punching tools and related machines and methods

Methods and related computer program products for processing a workpiece on a machine tool, including changing at least one control parameter of the machine tool based on a quantity of waste and/or good components discharged from the machine tool during processing of the workpiece, the at least one control parameter causing a change of at least one waste and/or good component container of the machine tool, wherein the quantity of waste and/or good components generated as a function of time during processing of the workpiece is determined before processing of the workpiece begins, and is stored in a numerical control program of the machine tool.

Processing workpieces on machine tools

A plate workpiece processing tool including a workpiece support defining a support plane for supporting a workpiece, a tool punch, a tool die, and a control unit configured to control movements of the tool punch and the tool die along a stroke axis. The tool punch and the tool die are displaceable, along the stroke axis, to a processing position above the support plane of the workpiece support such that the tool punch and the tool die are capable of processing a region of a workpiece having a formed shape that extends upwardly from the workpiece support.

Cutting and/or forming plate workpieces

The invention relates to disc-shaped compensation shims for compensating for the shortening of a tool die or a tool stamp due to regrinding. The shim includes a coding indicating a thickness of the tooling shim, the tooling shim being configured for use with a tool die or tool stamp to compensate for shortening of the tool die or tool stamp resulting from regrinding. The invention also relates to tool arrangements having at least one such shim, and to machine tools having such tool arrangements.

Tool wear compensation devices and related machines and methods

A machine tool that includes a workpiece support and a punching die. The punching die includes a support surface, for supporting a workpiece to be processed, and a discharging slope. The discharging slope is configured such that a workpiece part, severed from a workpiece supported on the support surface of the punching die, is displaced, in at least one of a rotational, tilting, or linear movement, from a processing position at least partially overlying the discharging slope toward a removal position on the discharging slope. The discharging slope is also configured such that a workpiece part, severed from a workpiece supported on the support surface of the punching die, is directed, in a sliding movement, toward a discharging position located beneath the support surface and adjacent the punching die.

Discharging workpiece parts

A method for processing a plate workpiece supported on a workpiece support. The method includes moving a tool die and a tool punch along a stroke axis and toward a processing position above a support plane of the workpiece support. The processing position corresponds to a region of the plate workpiece having a formed shape, which extends upwardly from the support plane of the workpiece support.

A plate workpiece processing method includes utilizing one or more cutting devices of a machine tool to perform first and second cutting operations on a plate workpiece. During the first cutting operation, the workpiece is moved relative to cutting device(s) used for the first cutting operation, at least two cut-outs are partially formed in the workpiece with only a common residual connection left that jointly connects the partially formed cut-outs to a remaining portion of the workpiece and that is shortened along one or more cutting lines of the second cutting operation to a size that is larger than a working area of the cutting device(s) used for the second cutting operation. During the second cutting operation, the workpiece is maintained stationary supported by the machine tool, the shortened common residual connection is severed along the cutting line(s) to completely separate the cut-outs from the remaining portion of the workpiece.
