Can you explain why it is important not to use the full deviation in both directions? Why wouldn't the machinist correct the full amount of X and Y to bring the holes back to nominal?
Thought I explained that above? Treat your hole as 2 Radii. If you move your Center point in the worst case direction, Draw a Radius with a protractor in the plus Direction lets say your X is your worst, and you draw a Radius in X minus, Your circle is complete. But you haven't accounted your Y, But YOUR CIRCLE IS COMPLETE, so the only thing your circle or your 2 Radii have in common is a center point, so you already accounted for the 2 Radii in each direction of X and you can't create 2 more Radii in the Y direction, You'll end up with a wollered hole or circle. Now if you shift the 2 Radii equally from the center, again because your circle is complete. if you move it half the deviation, Then the 2 radii will move equally in the Y direction, without distorting the circle, because It was already created in the X direction. If this is to complicated for you. I would strongly urge you not use this. <<<< not being rude, just don't know if I'm explaining my theory good enough, I'm stating it works for me.
I'm with Buck on this one. Why would you tell a machinist to only adjust half the deviation in one direction? No need for calculations when making adjustments to nominal...
