An efficient and accurate algorithm for generating circular arcs on arbitrary planes is presented and its implementation in the context of CNC is discussed. Besides having significant application potential as a CNC feature, it exemplifies a class of precise interpolation algorithms which can be developed on the basis of an integer programming formulation of Danielson’s step selection criteria.
