## Abstract

A method for machining a plate-like workpiece with a processing machine includes forming a receptacle in the plate-like workpiece for an insert part and machining the receptacle based on one or both of an orientation at which the insert part is to be inserted into the receptacle and a side of the plate-like workpiece from which the insert part is to be inserted into the receptacle. The method further includes running a machining program to carry out the forming and the machining of the receptacle. A computer program product is provided to configure a programming system by which the machining program is generated.

## Claims

### Claim 1

A method for machining a plate-shaped workpiece with a processing machine, the method comprising:
forming a round receptacle in the plate-shaped workpiece for an insert part having a non-round outer shape; and
machining a marking adjacent the round receptacle based on an orientation at which the insert part is to be inserted into the round receptacle on a side of the plate-shaped workpiece from which the insert part is to be inserted into the round receptacle and on which the insert part is to bear,
wherein the marking is provided as a non-round depression that encircles the round receptacle,
wherein the marking is positioned outside of the non-round outer shape of the insert part, and
wherein the marking is adapted to the non-round outer shape of the insert part.

### Claim 2 (depends on 1)

The method of claim 1, wherein the plate-shaped workpiece comprises a sheet metal plate.

### Claim 3 (depends on 1)

The method of claim 1, wherein the insert part comprises a weld nut or a rivet nut.

### Claim 4 (depends on 1)

The method of claim 1, wherein the plate-shaped workpiece is disposed horizontally during machining of the marking, the method further comprising machining the marking on an upper side of the plate-shaped workpiece.

### Claim 5 (depends on 1)

The method of claim 1, wherein the plate-shaped workpiece is disposed horizontally during machining of the marking, the method further comprising machining the marking on a lower side of the plate-shaped workpiece.

### Claim 6 (depends on 1)

The method of claim 1, further comprising punching an aperture in the plate-shaped workpiece to form the round receptacle.

### Claim 7 (depends on 1)

The method of claim 1, wherein the round receptacle is a first round receptacle, the insert part is a first insert part, the marking is a first marking, the orientation is a first orientation, and the side is a first side, the method further comprising:
forming one or more second round receptacles in the plate-shaped workpiece respectively for one or more second insert parts; and
machining one or more second markings respectively adjacent the one or more second round receptacles based on one or more second orientations at which the one or more second insert parts are to be inserted into the one or more second round receptacles and one or more second sides of the plate-shaped workpiece form which the one or more second insert parts are to be inserted into the one or more second round receptacles.

### Claim 8 (depends on 1)

The method of claim 1, further comprising running a machining program comprising control commands that control the forming of the round receptacle and the machining of the marking.

### Claim 9 (depends on 8)

The method of claim 8, further comprising running the machining program on a numerical control unit of the processing machine.

### Claim 10 (depends on 1)

The method of claim 1, wherein the processing machine comprises at least one of a punching device, a forming device, and a combined punching and forming device.
