Facing the front of the chuck, it turns counterclockwise in forward and clockwise in reverse.My chuck rotates clockwise
If milling in a lathe the same principles apply.

First picture if table moves to right that’s conventional. Second pic if table moved left it would be climbing.
I don't believe that the terms climb and conventional apply to a lathe. The cutter on a lathe is stationary so the only way to feed is to rotate the worki into the cutting edge. Rotating in the opposite direction would create a drag situation.
Not sure which is the right way for conventional milling in the attached pictures which one is for conventional milling?
I would say picture2 is conventional milling (stock pushed against the cutter)

My mill spindle does reverse direction of rotation, but I'm having a devil of a time getting my end mills to cut in reverse.Both, the DIRECTION of spindle rotation determines climb or conventional, does your mill spindle not rotate in both directions (-:
Turn them upside down, this should help.My mill spindle does reverse direction of rotation, but I'm having a devil of a time getting my end mills to cut in reverse.
