A system for regenerating fastener holes in a replacement tip section of a rotor blade includes a first fixture, a second fixture, and a third fixture positionable adjacent a tip section of the rotor blade. The first fixture is used to verify a position of an opening formed in the spar. The second fixture includes a removable bushing having a drillable opening. The drillable opening is aligned with the at least one opening formed in the spar and defines at least one hole to be formed in the replacement tip section. The third fixture includes a countersink opening. The countersink opening is aligned with the at least one hole to be formed in the replacement tip section and the at least one opening formed in the spar to define a countersink feature to be formed in the at least one hole.

A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.

A system for post-cure processing a composite workpiece includes a tool. The tool includes a tool surface. The tool surface supports the composite workpiece located on the tool. The system also includes a drill template. The drill template defines a drilling location for drilling a hole through the composite workpiece while the composite workpiece is on the tool.

A method of using a drill bit includes: S11, drilling, by a drill bit, a through hole in a board to be processed, and collecting a feedback time T of each conducting layer of the board by a drill tip; S12, determining a target layer and a reference layer of the board, and calculating a time difference t between the target layer and the reference layer; S13, determining a distance H between the target layer and the reference layer according to the time difference t and a drilling speed v of the drill bit; and S14, performing a controlled depth drilling by starting from the reference layer on the basis of the through hole and taking the distance H as a drilling depth.
