Abstract: Orientation error specifies the ranges of permissible variations of the relative position between the basis systems so that a manufactured part will be correctly oriented. The purpose of this paper is to continue creating a mathematical model of orientation error. This model is based on the mathematical coordinates transformation theory and can be used into a CAD system. The results from our earlier work show that the proposed math model is compatible with the standards, and that it provides threedimensional relations for orientation error. The project includes the implementation of the error analysis system into a CAD system.
