Paper Abstract

A novel device for testing internal threads' parameters is presented in this paper based on light sectioning approach, in which a line-shape light is projected on the internal surface of the tested thread, the distorted line is recorded and digitalized by a CCD camera, and a computer is used for further processing. A prototype system is built. The experiment results show that the accuracies of 10 micrometers for pitch measurement, 15 inch for tooth angle measurement and 15 micrometers for pitch diameter measurement have been achieved.
