Abstract:
INTRODUCTION
For a shot peener, it might seem intuitive to run the process
for an extended amount of time to achieve full coverage.
However, excessive peening wastes time and materials and
can have adverse effects on the surface [2]. Accurate characterization
of the rate of coverage increase can more precisely
predict the time required to achieve the desired coverage
specification.
One common method for characterizing shot peen
coverage and intensity is to insert an Almen strip into
the process. The Almen strip can be taken to the lab and
evaluated under a microscope to track the shot peening
process. However, material differences between the Almen
strip and the component, as well as component geometry can
lead to different coverage amounts on the component when
compared to the Almen strip [3]. A system that can assess
shot peen coverage on the component itself while it is being
processed will provide a more accurate assessment of the shot
peen coverage and save time.
