Abstract: A machining tool incorporates a shaft having a first end configured to fit into a machining collet. A cutting portion extends from a second end of the shaft. A residual stress inducer is located between the first and second ends and includes a torsion element joined to the shaft at a connection end. A carbide tip is present on a free end opposite the connection end and the torsion element is configured such that a selected rotational speed, altered from a normal cutting speed, causes the carbide tip of the torsion element to contact a workpiece surface.

Abstract: A tool for rotating a first component of an assembly relative to a second component of the assembly is disclosed. The tool comprises a ring support, a first wrench, coupled to the ring support, a worm ring, rotationally coupled to the ring support, a second wrench, coupled to the worm ring, and a worm screw, rotationally coupled to the ring support and in mesh with the worm ring.

Abstract: A tool (100) for rotating a first component (210) of an assembly (200) relative to a second component (220) of the assembly (200) is disclosed. The tool (100) comprises a ring support (130), a first wrench (110), coupled to the ring support (130), a worm ring (140), rotationally coupled to the ring support (130), a second wrench (120), coupled to the worm ring (140), and a worm screw (150), rotationally coupled to the ring support (130) and in mesh with the worm ring (°).

Abstract: A hole cleaning apparatus includes a member, a brush, and a vacuum source. The brush rotates around a longitudinal axis of the member, or translates in a direction which is substantially parallel to the longitudinal axis of the member. The vacuum source provides vacuum suction within the member.

Abstract: A debris removal apparatus for a milling machine. In one embodiment, the debris removal apparatus includes a hollow, cylindrical suction member that attaches to a tool shaft which holds an end mill to rotate with the tool shaft. The debris removal apparatus further includes a nonrotating canister that applies a suction force to the suction member. The suction member is dimensioned to fit within a hole being cut by the end mill as the end mill is fed into the hole, and to extract debris created by the end mill via the suction force.

Abstract: Described herein is an orbital drilling system that includes an orbital drilling machine and a cutter. The orbital drilling machine includes a spindle and an eccentric rotation mechanism. The spindle is rotatable about a cutter axis. The eccentric rotation mechanism is coupled to the spindle and configured to orbit the spindle about an orbital axis, offset from the cutter axis. The cutter is co-rotatably coupled to the spindle and comprises a plurality of cutting edges, collectively defining a cutting diameter of the cutter. The cutting diameter of the cutter is adjustable.
