Método y patrón de características geométricas para calibración y verificación de la medición con brazos articulados de medir por coordenadas

摘要

The invention concerns a method and template with geometric features for checking and calibrating measurements with articulated arms for measuring using coordinates, which comprises solid spheres, virtual spheres, planes, inner cylinders (44), (45) and outer cylinders (42), (43), (58), (59) and inner cones (48), (49) or outer cones. The invention concerns a particular selection and spatial arrangement of geometric features which enable numerous geometric and dimensional tolerances to be produced. The measuring of the geometric features and comparison thereof with reference values in different spatial positions enable both the measuring technique and apparatus to be evaluated, such that operatives can be trained or accredited with respect to their use. The invention also concerns a method for calibrating and verifying by means of this template. The invention can be applied in sectors in which calibration templates are designed, produced and used, such as industrial dimensional metrology preferably with portable or fixed machines which measure using coordinates.
