Abstract

In this paper, a vision-based inspection system has been proposed for the roundness error measurement of a cylindrical part. Evaluation is based on minimum zone (MZC) circle method as to comply with the definition of roundness error given by Y14.5M-1994 and ISO 1001. New approach in the system set-up and image capturing technique has been performed to be in line with the measurement requirement of this form tolerance. The result shows that this system can be used and implemented in the evaluation of roundness error of a cylindrical part. The advantage of using machine vision is the non contact nature of the measurement process which can be implemented in-process of making the cylindrical part.
