Abstract:
The Almen gage has been dominant process control device for shot peening since its introduction in 1942. The ability of this gage to accurately determine shot stream
intensity is related to its construction and maintenance. Attributes investigated included proper placement and wear of balls and indicator tip, and influence of indicator
tip spring force upon the Almen strip. A new calibration blcok, flat on one side and curved on the other to represent .024 inch arc height, is defined. A procedure for
checking Almen gage repeatability is described.
