Abstract:  
Academic Study by Dr. David Kirk INTRODUCTION Peening intensity curves are of vital importance for effective shot peening. They can be either continuously measured or intermittently indicated. The difference in approach can be illustrated by an everyday example. Imagine that a daily outdoor temperature curve is needed. We could connect a thermocouple to a chart recorder and set that to run for twentyfour hours. That would correspond to continuous measurement of temperature changes and give us a continuous curve. Alternatively we could record temperatures intermittently using, for example, the radio signals from a digital thermometer. These recordings could be plotted on a graph but they would only be an indication of a curve. We would have to invoke a curve-fitting procedure to deduce a possible continuous curve. Fig.1 illustrates the essential difference between the two procedures.
