Abstract

Industry uses a variety of devices to measure dimensions. Profile projectors are widely employed in metrology, and numerous factors affect measurement uncertainty. These elements must be understood for precise and traceable measurements. In co-ordinate metrology, ideal 2 or 3 dimensional geometric shapes are fitted against measured points to determine actual measurement results. Several approaches can fit geometric shapes to measured points. We determine the elements that affect Mitutoyo PJ-H3000F profile projector measurements of circular forms in this study. The paper examines connections between the number of the measurement points, diameter, and measurement error.
