Metrological Support for Detecting Holes in Bushings for Camshaft Joints

Abstract

The study examined the influence of bore gauge measurement errors on the formation of the number of incorrectly accepted and incorrectly rejected bushing holes under the camshaft journals cylinder blocks of YaMZ engines. The rationality of using the most accurate bore gauge from a range of universal instruments that satisfy the basic conditions for selecting measuring instruments has been scientifically substantiated and practically proven; otherwise, even if the selection condition is met, the percentage of losses increases in the form of sending such expensive parts as cylinder blocks to scrap.
