ABSTRACT
So far, we have reviewed the nondestructive techniques to find misalignment, studied good
baseplate and foundation design principles, looked at the multitude of flexible and rigid
couplings, reviewed the critical preliminary steps that should be performed prior to an
alignment job, covered a variety of measuring tools that are used in the alignment process,
and discussed how to position machinery to correct a misalignment condition. Sounds like we
are just about done with the entire subject at this point, but exactly how do we actually
measure the positions of the shafts? Once we get the shaft-to-shaft measurements, how do we
decide which way and how much of a move is required on the machinery to correct the
misalignment in the most efficient manner?
