Abstract
An apparatus for polishing an airfoil root includes a fixture for holding the airfoil, an actuation cylinder assembly for moving the fixture holding the airfoil, a brush, a motor for rotating the brush, a switch, and control circuitry. The actuation cylinder assembly is configured to move the fixture holding the airfoil toward the brush to trigger the switch, and the control circuitry is configured to run a timer when the switch is triggered to control contact between the airfoil and the brush for polishing.
