This paper describes a microcomputer controlled nozzle peening system which regulates the mass flow rate and velocity of the shot and enables a continuous recording of the peening cycle to be produced. A series of tests have been made on Almen strips with different shot flow rates. Results of arc height measurements are presented. Surface analysis results are presented which compare the finish produced by computer control to that of manual control. Descriptors: Microcomputer; Controlled; Nozzle peening
