Abstract

A live tool system having a live tool and a collar surrounding a rotating shaft or a rotating cutting tool of the live tool. The collar houses at least one sensor capable of monitoring an operating condition proximate to the cutting tool during a cutting operation. Example operating conditions including temperature and vibration. The system also includes a wireless transmitter in communication with the at least one sensor for transmitting a signal for use by a machining center controller.

Claims

1. A wireless monitoring kit for mounting to a live tool, comprising:

a collar configured to mount to the live tool such that the collar at least partially surrounds a rotating shaft of the live tool or a rotating cutting tool of the live tool, the collar comprising at least one sensor capable of monitoring an operating condition proximate to the cutting tool and during a cutting operation;

the collar being a collet chuck lock nut;

a transmitter unit comprising a wireless transmitter in communication with the at least one sensor for transmitting a signal for use by a machining center controller; and

a power source.

2. The kit of claim 1, wherein the at least one sensor is a temperature sensor and the operating condition comprises the temperature adjacent to the cutting tool.

3. The kit of claim 2, further comprising:

a wireless receiver capable of receiving signals sent from the wireless transmitter; and

a controller connector for operably connecting the wireless receiver to the machining center controller,

wherein the controller connector is configured to relay temperature information to the machine center controller for adjusting at least one function of the machining center in response to the temperature information.

4. The kit of claim 1, wherein the at least one sensor is a vibration sensor and the operating condition comprises vibration caused by the rotation and cutting operation of the cutting tool.

5. The kit of claim 1, wherein the collet chuck lock nut is a locking nut used to secure the cutting tool to the live tool.

6. The kit of claim 5, wherein the collar includes slots by which a tool can be used to tighten and untighten the collar relative to the cutting tool or the shaft.

7. The kit of claim 1, wherein the at least one sensor comprises a plurality of sensors.

8. The kit of claim 7, wherein the collar includes a plurality of cavities, each for receiving a respective one of the sensors.

9. The kit of claim 1, further comprising a bracket band for supporting the collar on the live tool.

10. The kit of claim 1, further comprising a transmitter connector band for connecting the wireless transmitter to the live tool.

11. The kit of claim 1, wherein:

the transmitter unit is mountable on the live tool at a location remote from the collar; and

the kit further comprises a cable for connecting the wireless transmitter unit to the collar.

12. The kit of claim 1, wherein the power source is located in the transmitter unit.

13. The kit of claim 12, wherein the transmitter unit further comprise a processor.

14. The kit of claim 1, wherein the collar includes at least one cavity within which the at least one sensor is mounted and/or supported.

15. The kit of claim 1, wherein the transmitter unit comprises an antenna.

16. A live tool system comprising, in combination:

the live tool, said live tool having at least one of the rotating shaft and the rotating cutting tool; and

the wireless monitoring kit of claim 1;

wherein;

the collar at least partially surrounds the rotating shaft or the rotating cutting tool; and

the wireless transmitter is in communication with the at least one sensor for transmitting a signal for use by the machining center controller.

17. The live tool system of claim 16, wherein the live tool is a fluid drive live tool.

18. The live tool system of claim 16, wherein the cutting tool is a mechanical cutting tool.

19. The live tool system of claim 16, wherein the at least one sensor is able to be retrofitted to the live tool without modification to the shaft or the cutting tool.

20. A method of monitoring a live tool, comprising:

providing the wireless monitoring kit of claim 1;

mounting the collar around at least one of the cutting tool, a collet, and the shaft of the live tool, the collar comprising the at least one sensor;

mounting the wireless transmitter unit to the live tool, the wireless transmitter unit in communication with the at least one sensor; and

sensing, using the at least one sensor, the operating condition during a cutting operation using the cutting tool;

transmitting a signal representative of the sensed operating condition to a wireless receiver in communication with the machining center controller; and

adjusting or terminating operation of the live tool when a predetermined sensed operating condition is detected.
