The case of articulated arms summarizes what has been told in the general discourse on calibration softwares. They are measurement machines, so their accuracy is a primary concern. In this case our software allows to compute a number of measurements taken on a known piece, so the error on those measurements can be minimized.

Furthermore, the choice of the error to be minimized ("maximum", "mean", "sigma" and/or their combinations) allow the user to compute the accuracy of the machine following the regulations of his own country.
