Abstract:  
Equipment and process techniques are described for fully automated deflector peening of bolt holes in a turbine engine disk. Unique design features of the equipment are presented along with the software path used to monitor process variables. The use of statistical process control (SPC) to select abort limits for air pressure and shot flow rate is also discussed. Descriptors: Shot peening; Computer; Software; Statistical process control
