MPE_E

Volumetric Length measuring error MPE_E

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".

MPE_P

Volumetric probing Error MPE_P

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).

MPE_THP

Volumetric Scanning probing Error MPE_THP

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.
