Abstract:
1. A method of optically inspecting manufactured rounds of ammunition or cylindrical components of the rounds to obtain rounds which exhibit superior accuracy when fired, the method comprising: providing a nominal numerical value and an acceptable range of numerical values for a size or a geometric characteristic of an acceptable manufactured round of ammunition or a cylindrical component of the round and a high-performance range of numerical values for the corresponding size or geometric characteristic of a high-performance manufactured round of ammunition or a cylindrical component of the high-performance round for a predetermined caliber of ammunition; optically gauging the size or geometric characteristic of a manufactured round of ammunition or cylindrical component of the round for the predetermined caliber at a vision station to obtain a measured value for the corresponding size or characteristic; determining whether the measured value is within the high-performance range of numerical values; and generating a signal if the measured value is within the high-performance range, the signal identifying the inspected round or a round including the inspected cylindrical component as having superior accuracy when fired relative to acceptable inspected rounds or inspected cylindrical components having a corresponding measured value which is outside the high-performance range but within the acceptable range of numerical values.
