Error Compensation of Coordinate Measuring Machines

Geometric error measurement and compensation of machines—An update

“…Kinematic errors are errors due to imperfect geometry and dimensions of machine components as well as their configuration in the machine's structural loop, axis misalignment and errors of the machine's measuring systems [1,41,28,89,45,134,158,126,127,116,130,8,128,2,121,95,44,62,96,48,123,153,12,17,46,118,90,19,20,166,170,171]. If the position of one axis influences the location and component errors of another, then the single errors of this axis are functions of the axis under test and of the influencing axis.…”

“…Due to the presence of, sometimes changing, internal and external heat/cold sources in machine tools and CMMs and the very often significant expansion coefficients and expansion coefficient differences of machine part materials, the resulting thermal distortion of the machine's structural loop often dominate the accuracy of an executed task [130,13,49,42,54,27,29,26,161,171]. Expansion coefficient differences may lead to thermal stresses if rules of exact constraint design have not been met carefully [121].…”

Typologie et conception des machines à mesurer tridimensionnelles : un état de l’art

“…C'est une hypothèse valide pour les machines à portique mais qui nécessite des modifications pour les machines à bras horizontal par exemple. [11] Si on reprend les notations classiques, pour la figure 17, on note pour décrire le vecteur rotation :…”

Generalized joint model for robot manipulator kinematic calibration and compensation

“…The coordinate measuring machine (CMM) modeled by Zhang et a1. 5 was of the moving-bridge configuration, as shown in Figure 3. The bridge moves in the Y direction.…”
