Abstract
A system and method for a composite finishing system. The composite finishing system comprises an abrasive bit with an abrasive material on a removal surface of the abrasive bit, where in the abrasive bit has a pilot structure that positions an abrasive surface relative to an edge break intersection of a hole in a composite structure when a pilot structure is placed into the hole.
Claims22
A composite finishing system comprising:
- an abrasive bit having a barrel body and a planar abrasive section at a distal end of the barrel body, wherein the abrasive section includes abrasive material on a removal surface wherein the removal surface comprises multiple radial channels extending from a pilot structure to an outer circumference of the barrel body, wherein the channels do not exceed the depth of the removal surface and are configured to allow debris to move away from the removal surface;
- and
- the pilot structure extending from the distal end of the barrel body that is perpendicular to the planar abrasive section and configured to position the removal surface in contact with an edge break intersection of a hole in a composite structure when the pilot structure is placed into the hole.
A method for removing inconsistencies from a hole in a composite structure, the method comprising:
- moving a pilot structure on an abrasive bit into the hole in the composite structure in a direction along a rotation axis for the abrasive bit, wherein the pilot structure extends from an end of the abrasive bit that has a first planar abrasive section with a first removal surface perpendicular to the rotation axis and configured to contact an edge break intersection of the hole when the pilot structure is placed into the hole, wherein the first removal surface comprises multiple radial channels extending from the pilot structure to an outer circumference of the abrasive bit, wherein the channels do not exceed the depth of the removal surface and are configured to allow debris to move away from the first removal surface;
- and
- rotating the abrasive bit while the pilot structure is in the hole, wherein abrasive material on the first removal surface of the abrasive section reduces undesired fibers from the edge break intersection of the hole.
