Abstract: Rather than machine tools, nowadays robots are used to some extent for the machining of workpieces. The robot holds the tool and machines the workpiece directly.

The invention is intended to make it possible to improve the feed by such robots or portal solutions such that the tolerances are reduced without substantially acting on the production processes. This is allowed by a table-mounted positioning apparatus, in which a positioning unit is connected to the table. The positioning unit has a position sleeve, into which the robot introduces an external holding device for receiving the workpiece, or for receiving the tool.
