Abstract

A method of manufacturing turned surfaces of a rotor disc of a gas turbine engine, including rotating the rotor disc about its central axis, rotating an abrasive grinding wheel having an outer grinding surface with a hardness greater than that of a material of the rotor disc, contacting the rotating wheel with at least one annular surface of the rotating disc, and sliding the rotating wheel along a curved cross-sectional profile of the at least one annular surface of the rotating disc.
