    Abstract: A rotary tool includes a shank, cutting portion, coolant inlet, coolant outlet, and channel system. The cutting portion is connected to and extends from the shank. The cutting portion includes a cutting edge. The coolant inlet and the coolant outlet are disposed in the shank. The channel system is contained in the rotary tool and is a closed circulation loop system such that the coolant is contained within the channel system as the coolant is circulated within the rotary tool. The channel system includes a delivery path and a return path. The delivery path is fluidly connected to the coolant inlet and includes a shape corresponding to a shape of the cutting edge. The return path is fluidly connected to the coolant outlet and to the delivery path at a location in the cutting portion of the rotary tool.

    Abstract: A method for controlled peening includes forming a surface layer on a workpiece by impacting a surface with a tool wherein the tool is under control to form compressive residual stresses in the surface layer. A system for peening a workpiece includes a tool configured to vibrate and an effector operatively connected to control the tool. The tool includes a peening surface. The tool is configured to cause controlled impact between the peening surface and a surface of a workpiece to form a surface layer of the workpiece with compressive residual stresses. The effector is configured to move the tool in multiple axes.

    Abstract: A blade includes a blade body extending from a blade root to an opposed blade tip surface along a longitudinal axis. The blade body defines a pressure side and a suction side. The blade body includes a cutting edge defined where the tip surface of the blade body meets the pressure side of the blade body. The cutting edge is configured to abrade a seal section of an engine case. A method for manufacturing a blade includes forming an airfoil with a root and an opposed tip surface along a longitudinal axis, wherein the airfoil defines a pressure side and a suction side. The method also includes forming a cutting edge where the tip surface of the airfoil meets the pressure side of the airfoil.
