Cutting tool data verification system and method

1. A method of operating a machining system comprising:

making a first comparison of one or more features of a cutting tool to information stored on a data chip secured to a tool holder of the cutting tool;

loading the cutting tool into the machining system only if a result of the first comparison is within a first threshold;

making a second comparison of the information stored on the data chip to cutting tool requirements of a machining program for instructing operation of the machine, the second comparison occurring after loading the cutting tool into the machining system;

measuring the one or more features of the cutting tool; and

making a third comparison of the measurements to the cutting tool requirements of the machining program, the third comparison occurring after the second comparison;

wherein operation of the machining system is stopped if a result of the second comparison is outside of a second threshold or if a result of the third comparison is outside of a third threshold.

2. The method of claim 1 , wherein the one or more features of the cutting tool are measured via a machine probe.

3. The method of claim 1 , wherein the one or more features comprise one or more of cutting tool length and cutting tool diameter.

4. The method of claim 1 , wherein the comparison of the information stored on the data chip to the cutting tool requirements of the machining program occurs automatically.

5. The method of claim 4 , wherein the comparison occurs automatically via a subprogram residing in a machining system controller.

6. The method of claim 1 , further comprising modifying the information stored on the data chip to correspond with measurements of the one or more features of the cutting tool.

7. The method of claim 1 , further comprising loading the cutting tool into a tool magazine after comparing the one or more features of the cutting tool to the information stored on the data chip.

8. The method of claim 1 , wherein loading the cutting tool into the machining system comprises installing the cutting tool onto the machine for use.

9. The method of claim 1 , wherein the machining program resides in a machine controller.

10. A machining system comprising:

a machine;

a cutting tool operably connectable to the machine, the cutting tool including one or more measurable features;

a tool holder receptive of the cutting tool, the tool holder including a data chip including information about the measurable features of the cutting tool, a result of a first comparison of the one or more measurable features to the information on the data chip within a first threshold resulting in the cutting tool being loaded into the machine;

a controller to perform a second comparison of contents of the data chip to cutting tool requirements of a machining program for instructing operation of the machine, the second comparison occurring after loading the cutting tool into the machine; and

a measurement tool to measure the measurable features of the cutting tool wherein the measureable features are comparable to the cutting tool requirements of the machining program after the second comparison occurring.

11. The machining system of claim 10 , wherein the measureable features comprise one or more of cutting tool length and cutting tool diameter.

12. The machining system of claim 10 , further comprising a subprogram residing at the controller to compare the contents of the data chip to the cutting tool requirements.

13. The machining system of claim 10 , further comprising a cutting tool magazine for storage of one or more cutting tools.
