ABSTRACT:
A disc component for a gas turbine engine is produced from a workpiece by a sequence of machining operations. During the machining operations, the workpiece is supported by a fixture engaging support surfaces. The workpiece remains secured to the fixture throughout the sequence of machining operations so that these operations can be conducted on both faces of a disc portion of the workpiece without removing the workpiece from the fixture. The machining operations are conducted alternately on the opposite faces in order to allow residual stresses in the workpiece to dissipate in a controlled manner.
