Abstract
A tool for measuring geometrical parameters of a vane or a blade of a turbomachine, particularly for measuring a distance between the tip of the vane or blade and a reference plane is provided. The tool includes a first guiding plate and a second guiding plate. The first guiding plate and the second guiding plate are spaced apart from each other in a defined position by means of at least two spacers. Each of the first guiding plate and the second guiding plate is equipped with a first through hole and one or more second through holes. The first through hole is designed to insert through an airfoil of said vane or blade. Each of the second through holes is designed to receive a length measuring tool, e.g. a depth gauge.
