The Society of Automotive Engineers, U.S.A. has recommended some methods of evaluating the quality of shot-peening, most of which are utilized widely in Japan. Accordingly, the measurements of archeight or coverage are commonly practised to control or to assure the effectiveness of peening operations. It was made clear, however, after study of some aspects of archeight, coverage and surface roughness under various hardness combinations of shots and specimens, that the above-mentioned SAE formulae are not always stable factors for verifying the peening effect and are valid under certain conditions. Furthermore, the possibility of "reflecting-surface shot-peening" is confirmed, and it's practical conditions or appicable ranges are fully explained.
