Abstract

Cutting tools and machining methods using cutting tools are disclosed. An example cutting tool comprises a shank and a head on the shank, the head comprising a diamond abrasive-coated cutting surface, the cutting head having grooves interrupting the cutting surface and extending from the cutting surface toward an axis of rotation of the head, the cutting surface having a substantially constant radius.

Claims

1. A cutting tool, comprising:

a shank; and

a head on the shank, the head comprising a diamond abrasive-coated cutting surface, the head having grooves interrupting the cutting surface and extending from the cutting surface toward an axis of rotation of the head, the cutting surface having a substantially constant radius.

2. A cutting tool as defined in claim 1, wherein the cutting surface is cylindrical, the head further comprises a planar end cutting surface, and an edge of the head between the cutting surface and the end cutting surface is radiused.

3. A cutting tool as defined in claim 2, wherein the grooves extend from the planar end cutting surface to an upper edge of the cutting surface.

4. A cutting tool as defined in claim 1, wherein the shank is to be operatively coupled to a Computer Numerical Control (CNC) machine.

5. A cutting tool as defined in claim 1, wherein the head is hemispherically shaped.

6. A cutting tool as defined in claim 1, wherein the grooves are helically shaped.

7. A cutting tool as defined in claim 1, wherein the cutting surface has the substantially constant radius in an axial direction of the head.

8. A cutting tool as defined in claim 1, wherein the cutting tool is to perform cutting with the diamond abrasive-coated cutting surface.

9. A method of applying a diamond abrasive cutting tool configuration to machining of a filler from a non-metallic composite material, comprising:

engaging a filler material sheet with a cutting tool, the cutting tool including a shank and a head on the shank, the head comprising a diamond abrasive-coated cutting surface, the head having grooves interrupting the cutting surface and extending from the cutting surface toward an axis of rotation of the head, the cutting surface having a substantially constant radius; and

machining a filler from the filler material sheet using the cutting tool.

10. A method as defined in claim 9, wherein engaging the filler material sheet comprises engaging the filler material sheet with a cylindrical cutting surface, the head further comprises a planar end cutting surface, and an edge of the head between the cutting surface and the end cutting surface is radiused.

11. A method as defined in claim 10, wherein the grooves extend from the planar end cutting surface to an upper edge of the cutting surface.

12. A method as defined in claim 9, wherein the shank is to be operatively coupled to a Computer Numerical Control (CNC) machine.

13. A method as defined in claim 9, wherein the head is hemispherically shaped.

14. A method as defined in claim 9, wherein the grooves are helically shaped.

15. A method as defined in claim 9, wherein the cutting surface has the substantially constant radius in an axial direction of the head.

16. A method as defined in claim 9, wherein the cutting tool is to perform cutting with the diamond abrasive-coated cutting surface.
