Off-the-Shelf Technology for Gun Barrel Straightness Measurement, 10th U.S. Army Gun Dynamics Symposium

Abstract

Gun barrel straightness is one of several manufacturing variables that must be held to a specified tolerance; therefore, barrel centerline measurement is a necessity. In the past, centerline measurement techniques have been developed specifically for this application, and machines to accomplish this have been produced on a small-quantity basis. This report describes the application of an off-the-shelf; three-dimensional laser tracker system, manufactured by Spatial Metrix Corporation (SMX), to measure the bore centerline of a 120-mm tank gun barrel. An introduction and tutorial about barrel straightness terminology, coordinate systems, and the level of precision required for such measurements are presented. A side-by-side comparison is then made between the SMX-based measurement and the standard or conventional measurement of several barrel centerlines, with the advantages and disadvantages of each system noted.
