Abstract:  
Interactive control of shot peening is based on continuous monitoring of peening intensity changes. The latest development in monitoring presented here involves the use of an elastically-strained arm carring a strain guage that is in contact with a disposable steel disc. As the disc deforms, due to peening, the arm relaxes with consequent strain guage signal changes being continuously chart-recorded. The divice has been used to study the effects of peening distance, air pressure and peened area on peening intensity/peening time changes. The very high sinsitivity of the strain guage device allows very small changes in intensity to be detected.
