Abstract

A process for manufacturing a composite rotor blade (84) includes manufacturing an oversized root region (88A) of a root region (88) of a composite rotor blade (84); fixturing the CMC blade (84) into a machining fixture at a primary Y and Z axis datum located at an attachment fillet radii (124) of the root region (88); machining V-notches (140, 142) into the oversized root region (88A) to form a Y' and Z' axis datum of a sacrificial datum system (144) in relation to the primary Y and Z axis datum; applying an oversized coating layer (160) over the attachment fillet radii (124) of the root region (88); fixturing the CMC blade (84) into a machining fixture at the Y' and Z' axis datum of the sacrificial datum system (144); machining the oversized coating layer (160) to a machined coating layer (170) forming a Y" and Z" axis datum with respect to the Y' and Z' axis datum of the sacrificial datum system (144); fixturing the CMC blade (84) into a machining fixture at the Y" and Z" axis datum; and machining off the sacrificial datum system (144) removing the V-notches (140, 142).
