Abstract

A cutter head ( 40 ) having cutting blade positioning slots ( 50, 52 ) wherein a portion of the positioning slots accommodate cutting blades ( 42 ) for right-hand cutting and another portion of the positioning slots accommodate cutting blades ( 46 ) for left-hand cutting.

First claim

What is claimed is:

1. A cutter head of a gear cutting tool for bevel and hypoid gears, said cutter head being generally disc-shaped and rotatable about an axis, said cutter head comprising:
a plurality of cutting blade positioning slots arranged in a face of said cutter head, wherein each of said plurality of cutting blade positioning slots extends through said cutter head from said face to an opposed surface of said cutter head;
wherein a first portion of said plurality of blade positioning slots are oriented to accommodate cutting blades whereby said cutter head is operable for right-hand cutting, and wherein a second portion of said plurality of cutting blade positioning slots are oriented to accommodate cutting blades whereby said cutter head is operable for left-hand cutting.

2. The cutter head of claim 1 wherein said first portion of blade positioning slots are oriented at a hook angle.

3. The cutter head of claim 1 wherein said second portion of blade positioning slots are oriented at a hook angle.

4. The cutter head of claim 1 wherein said blade positioning slots are arranged whereby said cutter head is operable for face milling.

5. The cutter head of claim 1 wherein said blade positioning slots are arranged whereby said cutter head is operable for face hobbing.

6. The cutter head of claim 1 wherein said blade positioning slots are arranged whereby said cutter head is operable with at least one of inside cutting blades and outside cutting blades.

7. The cutter head of claim 1 wherein said blade positioning slots are arranged whereby said cutter head is operable with full slot-width cutting blades.

8. The cutter head of claim 1 wherein said blade positioning slots are spaced equally about said cutter head.

9. The cutter head of claim 1 wherein a number of blade positioning slots for right-hand cutting and a number of blade positioning slots for left-hand cutting are equal.

10. The cutter head of claim 1 wherein blade positioning slots for right-hand cutting and blade positioning slots for left-hand cutting are arranged alternatingly about said cutter head.

11. The cutter head of claim 1 wherein said blade positioning slots accommodate cutting blades having a four-sided or five-sided cross-sectional shape.

12. The cutter head of claim 1 wherein said blade positioning slots accommodate cutting blades having a circular or semi-circular cross-sectional shape.
