Graphics and Analytics for Numerically Designed Nonlinear Surfaces 660353
This paper describes in some detail the method by which a typical airplane manufacturer derives and defines basic surface curves used in the engineering, tooling, and manufacturing of an airframe. The described system permits rapid and accurate surface development and has been proved to be thoroughly predictable. The ability to compute the coordinates and surface normals of a large number of arbitrarily selected points on a nonlinear surface is mandatory with numerical control applications. The described system affords this capability for the five axis part programming of compound surfaces.
