  abstract =   "This paper presents an efficient and robust algorithm for
               the geometric determination of swept volumes during the
               simulation of NC-milling (three-axis machining and five-axis
               machining). The boundary Y of the volume swept by a cutter F
               is represented polygonally by using instantaneous helical
               motions to exactly determine the line of contact between F
               and Y. Applying concepts of differential geometry allows a
               better and more efficient approximation of tool paths. Tool
               paths are explicitly calculated when a design surface G is
               to be milled along prescribed curves. We also describe how
               to quickly determine a polygonized representation of the
               truncated material during the milling process by means of
               'G-buffering'. This polygon-oriented algorithm is perfectly
               suitable for Boolean subtractions and error assessment.",
