True Position formulas?

I just want to know which are the TP formulas, for cartesian and polar measurements.
Thanks.

  • Sorry for bringing this subject back up, but I also wanted everyone to understand that my theory also applies to telling the machinist technically the same thing, when making adjustments. For instance right now, I have a part the holes he drilled are .0058 off in X and .0028 in Y. I will tell him to go .0058 in the correct direction of X and .0014 in the direction of Y. This is important not to use the full deviation in both directions.


    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?
