Abstract: A method and apparatus for accurately positioning successive turbine blades in a fixture in preparation for grinding of the root form and/or of the shroud thereof. The leading edge of the airfoil portion of each blade is supported by a vee block at first and second pairs of spaced locations and the concave surface of the blade is additionally supported adjacent its trailing edge by means of a pad member having a planar surface so oriented that the entire surface thereof coextensive with the concave surface is substantially contiguous therewith. The pad member is also so positioned relative to the vee block to assure a proper chord angle when the turbine blade is mounted on the rotational disk of the engine. In this manner, the stacking axis of each blade is substantially aligned with a predetermined axis within a tolerance range which is always less than the difference in size between a minimum contour and a maximum contour of the airfoil portion.
