Jerry, here is a link to a pdf file on the Fanuc site. It lists 13
canned cycles for one type of control, the Oi (the oldest and least
complicated one).

http://www.gefanuc.com/pdfs/0iCannedCycles.pdf

If you study the diagrams, it should become apparent that comparisons
between controllers is not a simple process at all. If you browse
through the Fanuc site, you will find that they have somewhere
between 5 and 8 different lines of controls *today*,each with it's
own unique feature set, and supporting some or all or more of the
same kinds of cycles. They also have 4-6 obsolete controls that are
not even listed. If you look at the various hobbyist configurations
that are included with VectorCam, you can see the variety in the
hobby class machines. They generally have similar functions, just
not as complicated, tending to omit rigid tapping and some others
that require spindle control on machines that do not have switched or
synchronized spindles.

This is just one manufacturer of probably 10 that are commonly sold
on industrial equipment at the present time. There are similar
charts for Fadal, Haas, Seimens, Milltronics, Centroid, Yasnac,
Mitsubishi, SouthWestern Industries, Bridgeport, etc. They all roll
their own and do things just a little different. Don't forget all
the obsolete and orphaned controllers too. Yikes! I am guessing that
there are over 200 and maybe over 300 identifiable, unique varieties
of controller and hence dialects of G-code.
