Abstract:  
In my fifteen years as a shot peening machine manufacturer, I have seen machines with multiple nozzles installed in facilities around the world. Many of these machines were purchased with extra nozzles so they could peen a wide range of parts. A few of these machine probably have operators that are guilty of the "spray and pray" approach to shot peening: Spray a lot of shot at the part and hope that it's peened to the proper intensity.
