00925njm 22002777a 4500 dc Quiroga Mellado, Juan Antonio author Rodríguez Ibáñez, Diego author Alonso Fernández, José author 2013-09 This paper proposes a calibration procedure for the squareness error of small-sized coordinate measuring machines like those used for ophthalmic lenses quality control. The proposed procedure only requires a spherical lens as a reference surface and it only needs to be measured once making this calibration method faster and cheaper than the existing ones. 0268-3768 10.1007/s00170-013-4746-y https://hdl.handle.net/20.500.14352/33371 http://dx.doi.org/10.1007/s00170-013-4746-y http://link.springer.com Squareness error calibration of a CMM for quality control of ophthalmic lenses
