CALIBRATION ANGLES AT THE LEVEL OF TENTH OF SECONDS

Walter Link, Marisa Ferraz Figueira Pereira
Abstract:
The main purpose of this paper is to show how to reach a high precision in calibration of angle measuring devices for industry. Actually, the demand for use of optical polygons is growing, manly for calibration of CNC machines, and so their own calibration. The article will deal with basic concept and the actual technology, giving information and testing results as well as the evaluation of the uncertainty using “CIRCLE CLOSURE”.
