Abstract

An apparatus for processing a ferrule with an abrasive element. The apparatus includes a first mount to which the ferrule is secured, a second mount to which the abrasive element is secured, and a controller operatively coupled to at least the second mount. The second mount includes a spindle to which the abrasive element is coupled, with the spindle having a central axis about which the spindle is configured to rotate. At least one of the first or second mounts is movable within a plane such that when the ferrule and the abrasive element are brought into contact with each other, the apparatus provides three degrees of freedom of movement for processing the ferrule with the abrasive element. A method of using the apparatus to process a ferrule is also disclosed.

First claim

What is claimed is:

1. An apparatus for processing a ferrule with an abrasive element, the apparatus comprising:
a first mount to which the ferrule is configured to be secured;
a second mount to which the abrasive element is configured to be secured;
and a controller operatively coupled to at least the second mount,
wherein the second mount includes an abrasive mount spindle to which the abrasive element is configured to be coupled, and the abrasive mount spindle has a central axis about which the abrasive mount spindle is configured to rotate,
wherein at least one of the first or second mounts is movable within a plane defined by at least one of the first or second mounts such that when the ferrule and the abrasive element are brought into contact with each other, the apparatus provides three degrees of freedom of movement for processing the ferrule with the abrasive element;
wherein the second mount includes a frame movable in at least two directions, wherein the abrasive mount spindle is mounted to the frame, and wherein the controller is configured to move the abrasive mount spindle within the plane;
and wherein the controller is configured to actuate the frame in a manner that causes the abrasive mount spindle to revolve around the ferrule during operation of the apparatus.

2. The apparatus of claim 1 , wherein the first mount is stationary and the second mount provides the three degrees of freedom of movement for processing the ferrule with the abrasive element.

3. The apparatus of claim 1 , wherein the controller is configured to actuate the frame so that the abrasive mount spindle revolves around the ferrule in a spiral path.

4. The apparatus of claim 1 , wherein the frame comprises an x-stage for moving the abrasive mount spindle in an x-direction and a y-stage for moving the abrasive mount spindle in a y-direction.

5. The apparatus of claim 1 , wherein the controller is configured to rotate the abrasive mount spindle about the central axis at an angular velocity greater than an angular velocity at which the abrasive mount spindle revolves around the ferrule.

6. The apparatus of claim 1 , wherein the first mount is movable relative to the second mount and provides at least one degree of freedom of movement for processing the ferrule with the abrasive element.

7. The apparatus of claim 6 , wherein the first mount comprises a ferrule spindle to which the ferrule is configured to be coupled, the ferrule spindle having a ferrule spindle axis about which the ferrule spindle is configured to rotate.

8. The apparatus of claim 7 , wherein the controller is configured to rotate the abrasive mount spindle about the central axis at an angular velocity greater than an angular velocity at which ferrule spindle rotates about the ferrule spindle axis.

9. The apparatus of claim 6 , wherein the second mount comprises a frame movable along a translation axis, and wherein the controller is configured to move the abrasive element along the translation axis.

10. The apparatus of claim 6 , wherein the first mount provides at least two degrees of freedom of movement for processing the ferrule with the abrasive element.

11. The apparatus of claim 10 , wherein the first mount comprises a frame movable in at least two directions, and wherein the controller is operatively coupled to the frame and configured to move the ferrule within the plane.

12. The apparatus of claim 7 , wherein the first mount provides at least two degrees of freedom of movement for processing the ferrule with the abrasive element and includes a frame movable along a translation axis, wherein the controller is operatively coupled to the frame and configured to move the ferrule within the plane along the translation axis.

13. The apparatus of claim 1 , wherein the controller is configured to cause relative movement between the first mount and second mount such that engagement of the ferrule with the abrasive element during the relative movement traces a spiral path in the abrasive element.

14. The apparatus of claim 13 , wherein the spiral path defines an Archimedean spiral.

15. The apparatus of claim 1 , wherein a ferrule assembly comprises the ferrule and at least one optical fiber coupled to the ferrule, and wherein the apparatus is configured for processing the ferrule assembly with the abrasive element.
