MPEE
Volumetric Length Measuring Error MPEE
A set of 5 gages has to be measured 3 times with one probing at each end, while the block is being aligned in 7 different directions in space. All measuring results must fulfil the Specification "E".
MPEP
Volumetric Probing Error MPEP
A Precision sphere has to be measured with 25 equally distributed probings. P is the range of all radii (sphere form). (Rmax - Rmin = Sphere form).
MPETHP
Volumetric Scanning Probing Error MPETHP
A precision sphere is to be scanned with 4 defined lines. THP is the range of all radii (sphere form-scanning) (Rmax - Rmin = Sphere form)
MF, MS, ML
Fixed Multiple-stylus Probing System Error MF, MS, ML
A precision sphere is to be measured with a 5 probe-star (fixed probe head) or with 1 probe in 5 different orientations (revolving probe head), with 5x25 probing. Form, size and location error over all 125 probings.
