Measurement of thread pitch of casing coupling using a laser triangulation 2D scanner

Abstract

An experimental setup was assembled for measuring of the thread pitch. An experiment to test the law of distribution of measurements of thread pitch of 2D laser scanner is held. Experimentally the optimal values of the angle of incidence of the laser beam to the surface plane of the thread tooth and the exposure time of matrix of scanner are calculated. The possibility to meet regulatory requirements to measurement error was experimentally confirmed by means of 2D laser scanner.
