Evaluation of Modified Bore Erosion Gage

摘要

A bore erosion gage developed earlier (Krupski and Audino, WVT (1977)) for monitoring the coating thickness and erosion of the 105 mm M68 in the region up to 40 inches from the origin of rifling has been modified, and the problem of the lack of responsibility of radius measurements along the bore circumference has been successfully eliminated. Test data and statistical analysis of the results have demonstrated that the modified gage can measure the relative change in the bore radius with an accuracy of + or - 0.005 inch. The statistical accuracy can be further improved by increasing the number of data points.
