backlash was Re: Comments from expert PID programmers?

Ron, Group,

I just did a yahoo search on "climb milling metal". This link was one
of, if not the first:

http://ase.tufts.edu/mechanical/shop/classes/me1/milling.html

Scroll about halfways down the page--to the pic of climb vs.
conventional milling...

Notice what it says ABOVE the picture?

This is from a university course, and is obviously for beginners
(like this CCED group).

FWIW, There are literally thousands of other places this WELL-known
advice is given as part of "basic" mill/metalworking instruction. And
it has been given for decades. (WAAaaay before 1971...)

Hope this helps,

Ballendo
