Abstract

Insert pockets of tool holders configured to accommodate multiple differently-shaped cutting inserts are disclosed. Cutting tool holders and cutting tool systems are also disclosed.

Claims (40)

1. A cutting insert pocket of a tool holder, the cutting insert pocket comprising:

a seat face configured to engage either one of a top side and a bottom side of a double-sided cutting insert;

at least two insert-engaging pocket walls configured to engage peripheral sides of multiple differently-shaped double-sided cutting inserts, the insert-engaging pocket walls having an angle less than or equal to 90 degrees with respect to the seat face; and

a relief recess located between and separating the seat face and the at least two insert-engaging pocket walls, the relief recess configured to provide clearance space for the cutting edges of multiple differently-shaped double-sided cutting inserts positioned and secured in the pocket;

wherein the cutting insert pocket is configured to accommodate a round-shaped double-sided cutting insert and at least one polygon-shaped double-sided cutting insert.

2. The cutting insert pocket of claim 1 , comprising:

more than two insert-engaging pocket walls configured to engage the peripheral sides of the multiple differently-shaped double-sided cutting inserts, each of the more than two insert-engaging pocket walls having an angle less than or equal to 90 degrees with respect to the seat face; and

more than two non-engaging pocket walls configured to not contact multiple differently-shaped double-sided cutting inserts positioned and secured in the pocket.

3. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least two different polygon-shaped cutting inserts.

4. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least three different polygon-shaped cutting inserts.

5. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a hexagon-shaped cutting insert, and an octagon-shaped cutting insert.

6. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a pentagon-shaped cutting insert, and a heptagon-shaped cutting insert.

7. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a square-shaped cutting insert, and an octagon-shaped cutting insert.

8. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a pentagon-shaped cutting insert, and a decagon-shaped cutting insert.

9. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, an octagon-shaped cutting insert, and a dodecagon-shaped cutting insert.

10. The cutting insert pocket of claim 1 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a square-shaped cutting insert, a pentagon-shaped cutting insert, and an octagon-shaped cutting insert.

11. A tool holder comprising:

a cutting insert pocket comprising:

a seat face configured to engage a top side or a bottom side of multiple differently-shaped double-sided cutting inserts;

a series of insert-engaging pocket walls configured to engage peripheral sides of the multiple differently-shaped double-sided cutting inserts, the insert-engaging pocket walls having an angle less than or equal to 90 degrees with respect to the seat face;

a series of non-engaging pocket walls configured to not contact the multiple differently-shaped double-sided cutting inserts positioned and secured in the pocket; and

a relief recess located between and separating the seat face and the series of insert-engaging pocket walls, the relief recess configured to provide clearance space for the cutting edges of the multiple differently-shaped double-sided cutting inserts positioned and secured in the pocket;

wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least one polygon-shaped cutting insert.

12. The tool holder of claim 11 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least two different polygon-shaped cutting inserts.

13. The tool holder of claim 11 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least three different polygon-shaped cutting inserts.

14. The tool holder of claim 11 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a hexagon-shaped cutting insert, and an octagon-shaped cutting insert.

15. The tool holder of claim 11 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a pentagon-shaped cutting insert, and a heptagon-shaped cutting insert.

16. The tool holder of claim 11 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a square-shaped cutting insert, a pentagon-shaped cutting insert, and an octagon-shaped cutting insert.

17. A cutting tool system comprising:

a cutting insert; and

a tool holder comprising:

a cutting insert pocket comprising:

a seat face configured to engage a top side or a bottom side of multiple differently-shaped double-sided cutting inserts;

a series of insert-engaging pocket walls configured to engage peripheral sides of the multiple differently-shaped double-sided cutting inserts, the insert-engaging pocket walls having an angle less than or equal to 90 degrees with respect to the seat face;

a series of non-engaging pocket walls configured to not contact the multiple differently-shaped double-sided cutting inserts positioned and secured in the pocket; and

a relief recess located between and separating the seat face and the series of insert-engaging pocket walls, the relief recess configured to provide clearance space for the cutting edges of the multiple differently-shaped double-sided cutting inserts positioned and secured in the pocket;

wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least one polygon-shaped cutting insert.

18. The cutting tool system of claim 17 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least two different polygon-shaped cutting inserts.

19. The cutting tool system of claim 17 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert and at least three different polygon-shaped cutting inserts.

20. The cutting tool system of claim 17 , wherein the cutting insert pocket is configured to accommodate a round-shaped cutting insert, a hexagon-shaped cutting insert, and an octagon-shaped cutting insert.
