Abstract

The blade root grooves in a turbine disc are gauged for accuracy by a body resembling the blade root which includes electronic distance gauges in its surfaces. The body is introduced into a reference groove with two surfaces in contact with the groove surfaces of the body and the corresp. surfaces of the reference groove displayed. The display is adjusted so that all the distances displayed are equal. The body may then be introduced into a disc groove during production and will indicate whether the disc groove being machined corresponds to the reference groove.
