BORE QUALITY OF SHOTGUN BARREL BLANKS

Abstract

This paper provides a novel manner of shotgun barrel bore surface texture specification. The current state of shotgun barrel blank bore surface texture specification and measurement is analyzed. Comparative measurements of samples with good and inferior surface quality are used to demonstrate the shortcomings of current specifications. In seeking improvement, six profile parameters are evaluated and their sensitivity to prevalent surface imperfections is determined. Similarly, six areal parameters are evaluated, and suitable measurement settings are determined for the most sensitive one. The parameters are ranked according to their level of sensitivity to change in bore surface quality. Based on all of the above, profile and areal parameters particularly suitable for specification of shotgun barrel bore surface texture are singled out.
