Performance Verification
MPEeo: Maximum permissible error on lenght measurement with standard probe OFFSET
Measurement of a set of 5 sizes, taken through two opposite probing points on two nominally parallel planes. the sizes are positioned with direction on the 4 volume diagnols and in 3 different positions chosen by the customer (or along the axes according to the standard) in the measurement volume. Each size is measured 3 times for a total of 105 measurements. All 105 measurements (100%) must be within the specified MPEeo.
MPEe150: Maximum Permissible Error on length measurement with probe OFFSET 150mm
Measurement of 1 set of 5 different sizes in 2 diagonal positions on the XZ or YZ plane with a probe OFFSET of 150mm. All 30 measurements must be less than the maximum permissible error MPE E150.
MPLr0 : Maximum Permissible Repeatability Limit
Evaluation of the 35 repeatabiliy values calculated from the difference between the maximum and minimum values of the three differents measurements made on the same length size on each of the 5 samples in each of the 7 positions. Each of these 35 R0 value must be less than the maximum permissible limit MPLR0.
MPE(PFTU): Maximum permissible single stylus form error
A reference sphere is measured with 25 equally distributed probings, estimate of the deviation in the shape of the sphere, obtained as a dispersion band of the 25 polar rays. The probing perfomance shall be verified in one position, placed in the middle of the CMM measure volume. Calculation of the gaussian sphere using the 25 measures. Calculation of the radial distances R, for each of the 25 measured points.Calculation of the PFTU point gripping error, as dispersion band of the 25 radial distances, Rmax-Rmin. The PFTU error must be within the MPE(PFTU).
