Abstract: A tape course generator produces tape course definitions for use in programming a CNC composite tape lamination machine. The tape course generator includes a reference surface parameterizer that maps a contoured surface onto a parametric reference surface, and a reference plane instantiator that maps the reference surface onto a reference plane. The tape course generator also includes a tape boundary plotter that plots a tape boundary, and a boundary mapper that maps the tape boundary and a ply boundary into the reference plane. In addition, the tape course generator includes an intersection locator that identifies intersections of the ply boundary and the tape boundary, and a tape course delimiter that defines tape cuts and determines which points in the reference plane are within a tape course. Moreover, the tape course generator includes a tape course transformer that maps the defined tape course back onto the contoured surface.

Abstract: A method of defining a composite tape course to form at least a portion of a composite part ply comprises approximating a contoured surface with a reference plane. The method further includes selecting a three-dimensional reference surface to approximate the contoured surface and defining a first function to correlate a first point from the contoured surface to a first intermediate point on the reference surface. The method includes selecting the reference plane to approximate the reference surface, defining a second function to correlate the first intermediate point to a reference point in the reference plane, and mapping a ply boundary from the contoured surface to a reference ply boundary in the reference plane. A tape boundary may be mapped from the contoured surface to a reference tape boundary in the reference plane.
