Well, it depends on where you are standing. But, for
a Bridgeport type machine, where the X axis translates
left to right, and the Y is front-back and Z is up-down,
then A== pitch, B== roll, and C==yaw, assuming you
are standing in front of the machine so that the X does
move left and right from your perspective. Don't ask
me about the signs, though! It gets complicated, as the
motions of the machine are measured FROM the parts
perspective!
