Abstract: A numerical control method and apparatus for directing a controlled element such as a cutting tool through a fairing contour between two normally intersecting linear displacement segments. The fairing contour is an approximation of a parabola, the actual tool path comprising a number of contiguous linear segments, the end point coordinates of which are calculated by a relatively simple arithmetic process. Both programmable and hardwired computer implementations are disclosed.
