robing size error All
PSize.Sph.All:j:ODS
error of indication of the difference between the diameter of a least-squares fit of all points measured on a test sphere and its calibrated diameter
Note 1 to entry: The symbol “P” in PSize.Sph.All:j:ODS indicates that the error is associated with the probing system performance, the qualifier “Size.Sph” indicates that it is associated with the probing size error, the qualifier “All” indicates that all measuring points are used for the calculation and the qualifier “ODS” indicates that it is associated with the optical distance sensor. The qualifier “j” identifies the measuring conditions of the CMM. PSize.Sph.All:Tr:ODS is the optical probing size error translatory, which is given when the sensor is moved by the CMM and measurements are taken at several positions. PSize.Sph.All:Art:ODS is the optical probing size error articulating, which is given when the alignment of the sensor is additionally modified by means of an articulating system. PSize.Sph.All:St:ODS is the optical probing size error stationary, which is given when the sensor is not moved by the CMM during measurements (see Figure 3).
Note 2 to entry: Probing size error All is determined by the errors of the sensors (such as noise, digitizing errors, image distortion, optical interaction with the surface of the material standard, calibration errors of the sensor, faulty algorithms in measured data processing) and those of the CMM.
