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)
