2. The method as in claim 1 , wherein a first cylinder provides a force in a first direction to pass the workpiece through the hone tool.
3. The method as in claim 2 , further comprising:
applying a force to the workpiece in a direction opposite to the first direction to prevent misalignment of the workpiece with respect to the hone tool, the force in the first direction being greater than the force in the direction opposite to the first direction.
4. A method for honing a workpiece, comprising:
stacking a plurality of workpieces on a first assembly;
providing a force in a first direction to the plurality of workpieces by the first assembly to pass the plurality of workpieces through a plurality of hone tools each being free moving with respect to each other in a rotational direction about an axis parallel to the first direction and each of the plurality of hone tools has a plurality of abrasive surfaces disposed in an opening, wherein each opening of the plurality of hone tools is smaller in size with respect to an opening of an adjacent hone tool and the plurality of abrasive surfaces in each opening are configured to remove a portion of all exterior surfaces of the plurality of workpieces as they are passed through the plurality of hone tools, wherein each of the exterior surface of the plurality of workpieces are non-uniform in configuration and each of the plurality of hone tools are configured to simultaneously hone all of the exterior features of each of the plurality of workpieces being passed through the hone tools.
5. The method as in claim 4 , further comprising:
applying a force to the plurality of workpieces in a direction opposite to the first direction to prevent misalignment of the plurality of workpieces with respect to the plurality of hone tools, the force in the first direction being greater than the force in the direction opposite to the first direction.
6. The method as in claim 5 , further comprising:
locating a spacer between each of the plurality of hone tools.
7. The method as in claim 6 , wherein each spacer has a thickness greater than a thickness of each workpiece.
8. The method as in claim 7 , wherein each spacer has a feature configured to maintain a radial orientation between each of the plurality of hone tools by engaging at least one exterior feature of each of the plurality of workpieces being passed through each of the plurality of hone tools and each of the plurality of abrasive surfaces is chamfered at the opening of each hone tool.
9. The method as in claim 6 , wherein each spacer has a feature configured to maintain a radial orientation between each of the plurality of hone tools by engaging at least one exterior feature of each of the plurality of workpieces.
10. The method as in claim 9 , wherein each workpiece is a gear.
11. The method as in claim 4 , further comprising:
rotationally supporting the workpieces on the first assembly with a bearing assembly.
12. The method as in claim 4 , further comprising:
surrounding each of the plurality of hone tools with a sleeve.
13. The method as in claim 12 , further comprising:
applying a force to the plurality of workpieces in a direction opposite to the first direction to prevent misalignment of the plurality of workpieces with respect to the plurality of hone tools, the force in the first direction being greater than the force in the direction opposite to the first direction; and
locating a spacer between each of the plurality of hone tools.
14. The method as in claim 13 , wherein each spacer has a thickness greater than a thickness of each workpiece and wherein each spacer has a feature to maintain a radial orientation between each of the plurality of hone tools and each of the workpieces being passed through each of the plurality of hone tools and each of the plurality of abrasive surfaces is chamfered at the opening of each hone tool and wherein each hone tool is configured to surround the entire periphery of the workpiece being passed through the hone tool.
15. An assembly for honing a workpiece, comprising:
a plurality of hone tools each having abrasive surfaces configured to remove a portion of exterior non-uniform surfaces of a workpiece pushed through an opening in each of the plurality of hone tools, wherein each hone tool is configured to surround and simultaneously hone the entire periphery of the workpiece being passed therethrough.
16. The assembly as in claim 15 , wherein a spacer is disposed between each of the plurality of hone tools.
17. The assembly as in claim 16 , wherein the opening in each of the plurality of hone tools is smaller in size with respect to an opening in an adjacent hone tool and the abrasive surfaces proximate to each opening are configured to remove a portion of exterior non-uniform surfaces of the workpiece as it passed through the plurality of hone tools.
18. The assembly as in claim 17 , wherein the abrasive surfaces of each of the plurality of hone tools is chamfered at the opening and each spacer further comprises a geometric feature for aligning the workpiece with each of the plurality of hone tools.
19. The assembly as in claim 16 , wherein the workpiece is rotationally supported on a first actuator assembly for providing a force in a first direction to push the workpiece through the plurality of hone tools and the assembly further comprises a second actuator assembly for providing a force to the work piece in a direction opposite to the first direction, the force in the first direction being greater than the force in the direction opposite to the first direction.
20. The assembly as in claim 19 , wherein the plurality of hone tools are surrounded by a sleeve.
