Abstract

A removable assembly (38) comprising an information holding unit (36). The removable assembly is positionable in a material object (2), such as a tool, tool component or part, machine, machine component or part, device, etc., and can be removed therefrom by fluid pressure whereby the material object can be subjected to processing that would otherwise cause damage to, or destroy, the information holding unit (36).

Claims

1. A gear producing assembly for producing gears, the assembly comprising:

a gear cutting tool comprising a passageway having a first opening at one end of the passageway and having a second opening at an opposite end of the passageway;

a removable assembly comprising an information holding unit wherein said removable assembly is positionable in said passageway, and

wherein said removable assembly is configured to be held in place in the passageway via a seal, and is configured to be removed from the second opening via fluid pressure against the removable assembly via fluid provided to the first opening.

2. The gear producing assembly of claim 1 wherein said first opening comprises an inlet for said fluid pressure, said first opening and said second opening being in fluid communication with one another.

3. The gear producing assembly of claim 1 wherein said removable assembly further comprises a carriage.

4. The gear producing assembly of claim 3 wherein said information holding unit is located within said carriage.

5. The gear producing assembly of claim 1 wherein said removable assembly further comprises the seal.

6. The gear producing assembly of claim 1 wherein said information holding unit comprises a radio frequency identification device.

7. The gear producing assembly of claim 1, wherein the gear cutting tool comprises a hobbing tool.

8. The gear producing assembly of claim 7 wherein said hobbing tool includes a shank, wherein said removable assembly is positionable in and is removable from said shank.

9. The gear producing assembly of claim 1 wherein the gear cutting tool comprises a shaper cutter.

10. The gear producing assembly of claim 9 wherein said shaper cutter comprises a tool body having an outer surface, wherein said removable assembly is positionable in and is removable from said outer surface.

11. The gear producing assembly of claim 1 wherein said gear cutting tool and said removable assembly are each coded with like symbols so as to aid in matching said gear cutting tool and said removable assembly.

12. A method comprising:

providing the gear producing assembly set forth in claim 1;

removing said removable assembly from said tool by applying said fluid pressure to said removable assembly,

processing said tool wherein said processing comprises conditions that would damage or destroy said information holding unit had said information holding unit not been removed from said tool, and

inserting said removable assembly into said tool.

13. The method of claim 12 wherein said processing comprises at least one of the steps of stripping a wear coating from said tool, sharpening said tool and applying a wear coating to said tool.

14. The method of claim 12, wherein said first opening comprises an inlet for said fluid pressure, said first opening and said second opening being in fluid communication with one another.

15. The method of claim 12 wherein said tool comprises a hobbing tool.
