I certainly get confused here also, but from my
Machinery's Handbook, 26th Ed:

Relating to Axes Nomenclature "The assignment of these
letter addresses has been standardized on a worldwide
basis and is contained in three standards, all of which
are in agreement. These standards are EIA RS-267-B,
issued by the Electronics Industries Association;
AIA NAS-938, issued by the Aerospace Industries
Association; and ISO/R 841, issued by the International
Organization for Standardization."

Machinery's Handbook has a good section on what these
standards specify, and this matches what Ballendo and
others have been describing.

FYI, this edition of Machinery's Handbook lists two
pages of "Numerical Control Standards".

Hope this helps.
