This laser calibration system is capable of evaluating the positioning accuracy of a numerically controlled axis of machine tools and coordinate measuring machines (CMM) under dynamic conditions. In order to assess the measurement uncertainty of this calibrator, an analysis of the uncertainty components that make up the uncertainty budget of this calibrator has been carried out. These uncertainty components can be classified into three categories as follows: (1) uncertainties intrinsic to the laser system; (2) uncertainties due to environmental effects; (3) measuring uncertainties due to the installation. The procedure for evaluating the uncertainty of this calibrator follows GUM (“Guide to the Expression of Uncertainty in Measurement”). This uncertainty analysis was carried out when this calibrator was used to assess the positional errors of the “X” axis of a moving bridge type CMM.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-07-05T13:55:39Z No. of bitstreams: 1 __ac.els-cdn.com_S014163...fcaf9c3d1fa14e606c5149dd2c84f.pdf: 194917 bytes, checksum: a12124bb5198d605e2820b9d132cacfc (MD5)Made available in DSpace on 2012-07-05T13:55:39Z (GMT).
