Abstract:
INTRODUCTION
Generally speaking, the management of shot peening would be conducted by arc height intensity, coverage and deformation of part. As standard method of measurement of
coverage, it should be required to use the strip that has the same hardness and material of the target. However, usually normal almen strip is used in place of correct
specimen for coverage measurement.
As standard method of coverage measurement, it is required to calculate by checking the weight rate of piece that was cut from an enlarged photo. Further at simplified
method it is requested to decide the coverage by comparing with the standard photo. The former method takes a longer measurement time and the latter is basically depend on
the skill.
So, in this paper we would suggest new measurement method to avoid above two problem by using mirror polished almen strip and image processing.
