Abstract
A method for in-place machining of a collector ring attached to a turbine shaft of a hydroelectric generator includes: attaching a support member to stationary portions of the hydroelectric generator, the support member being configured to support a machine tool at an angle parallel to an inclination angle of an axis of rotation of the turbine shaft; attaching an adjustable positioning device to the support member; attaching the machine tool to the adjustable positioning device, the machine tool being configured to perform a machining operation on the collector ring; controlling a rotational speed of the turbine shaft to a specified rotational speed by controlling a flow of water through the turbine; adjusting the adjustable positioning device to adjust a position of the machine tool with respect to the collector ring; and performing the machining operation on the collector ring at the specified rotational speed of the turbine shaft.
