Abstract
AbstractThe paper presents results of investigations on the direction-dependent accuracy of the point identification during contact probe measurement with a Coordinate Measuring Machine (CMM). Considering the contact point identified by orthogonal to the surface probe movement, transformation of coordinates was made in order to calculate the displacement of the measured point. As a result, positioning accuracy was estimated in three axes. The experiments demonstrated strong dependence of the displacement on the declination angle. Moreover, it was found that the directional surface texture which provided different roughness in perpendicular directions, had impact on the positioning accuracy.KeywordsCoordinate measuring machineAccuracyProbing point
