Abstract

A machine tool monitoring device of a machine tool for machining a work piece, includes a signal unit (24) provided for an ultra-broad-band operation. The signal unit (24) processes a signal (32, 34), which has a sequence (46) of pulses (48) and includes an arithmetic-logic unit (40) for associating a detected signal (34) with a use situation (52, 58) by means of a fuzzy logic-based and/or neural logic-based signal processing. The signal unit (24) preferably has a programmable data base (44) in which a use situation (52, 58) in a machining process is associated with a procedure (56, 60) for changing the machining process.

Claims

1. A machine tool monitoring device of a machine tool for machining a work piece, comprising:

a signal unit (24) provided for an ultra-broad-band operation,

wherein the signal unit (24) has a programmable data base (44) in which a use situation (52, 58) in a machining process is associated with a procedure (56, 60) for changing the machining process,

wherein the signal unit (24) includes an arithmetic-logic unit (40) that is provided for associating a detected signal (34) with a use situation (52, 58) by means of a fuzzy logic-based and/or neural logic-based signal processing.

2. The machine tool monitoring device as recited in claim 1, wherein the signal unit (24) is provided for processing a signal (32, 34), which has a sequence (46) of pulses (48).

3. The machine tool monitoring device as recited in claim 1,

wherein the signal unit (24) is provided for determining a work progress in a machining of a work piece.

4. The machine tool monitoring device as recited in claim 3, wherein the signal unit (24) is provided for determining a distance (62, 64).

5. The machine tool monitoring device as recited in claim 1,

wherein the signal unit (24) is provided for determining a speed (V) of a work piece (50) to be machined.

6. The machine tool monitoring device as recited in claim 5, wherein the signal unit (24) has a data base (44) in which a use situation (52, 58) is associated with at least one signal pattern (54, 59).

7. The machine tool monitoring device as recited in claim 5, further comprising an electronic output device (18) that is provided for outputting a piece of monitoring information to a user.

8. The machine tool monitoring device as recited in claim 5, further comprising an electronic input device (20) that is provided for inputting at least one piece of monitoring information.

9. The machine tool monitoring device as recited in claim 1,

further comprising a regulating device (26) that is provided for regulating at least one parameter (68) of a work piece machining process.

10. A machine tool, comprising:

a machine tool monitoring device, said machine tool monitoring device comprising a signal unit (24) provided for an ultra-broad-band operation,

wherein the signal unit (24) has a programmable data base (44) in which a use situation (52, 58) in a machining process is associated with a procedure (56, 60) for changing the machining process, and wherein the signal unit (24) includes an arithmetic-logic unit (40) that is provided for associating a detected signal (34) with a use situation (52, 58) by means of a fuzzy logic-based and/or neural logic-based signal processing.
