MM&T Advanced Balancing/Machining

Abstract

A laser balancing system was developed and successfully demonstrated. The system uses a pulsed Nd:YAG laser to remove metal from the part while it is rotating in the balancing machine. Computer algorithms were developed which accepted imbalance information from the balancing machine and generated firing signals for the laser. This system balanced AGT1500 compressor impellers to less than one half the allowable imbalance under full computer control. Preliminary low cycle fatigue testing showed no major differences between laser irradiated test bars and hand ground and burnished test bars. Keywords: Balancing, Laser, Turbine Engines, Machining.
