Oops, I got my X's and Y's mixed up.

Dyslexics of the world,,, UNTIE !

Somehow or another untie actually does sound better!

To be honest with you, I have no trouble with x, y, or z on a Mill. But the only one I ever get right on a lathe is Z!

I have no clue on a surface grinder.

If anyone has a little ditty or memory jog, it would be appreciated by a whole raft of us untied sickos.

On a SG, the convention I was introduced to is the left/right motion is X, the motion towards you is Z and the up/down is Y.

This is because the spindle is always Z, and the most common or longest motion is X, and the remaining must be Y.

Yes, that's why I always have no trouble with Z - it is always the spindle axis of rotation.

It's X & Y I have trouble with.

Makes some sense to make the long axis X.
