ABSTRACT:
A process and apparatus are disclosed for the precision measurement of the height of turbine rotor blades which enables the measurement of the height of individual turbine blades by utilizing a stroboscopically controlled laser beam. A grinding wheel is also associated with the apparatus to reduce the height of the blade when it exceeds a predetermined value. The measurement and control of the rotor blade is achieved while the turbine wheel is being rotated at speeds sufficient to centrifuge all of the blades to their maximum radially outward position.
