Abstract
An apparatus and method for fabricating accurate, numerically defined curved surfaces and volumes comprising a skeleton framework having a plurality of bulkheads fixed in spaced relationship with each other, each of the bulkheads having an equal number of boreholes passing through the outer perimeter thereof so as to provide a set of selected boreholes. A flexible spline having a memory is passed through each set of mating boreholes and is secured with the boreholes after the splines have reached their static states. The resultant framework is encased in a cured polymer and the polymer is trimmed and faired between the outer edges of the splines.
