Abstract: A robotic deburring process that automatically, accurately, and efficiently removes burrs from a workpiece. The robotic deburring process uses CAM location data to establish deburring trajectory, physics based machining models to predict burr type and size, and force control functions to compensate inaccuracies due of inaccuracies of robots arms.

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.
