Abstract
A casting die, for forming a segmented mirror, is formed by the steps including: providing a negative or positive casting of the desired continuous surface shape; cutting the casting into small segments to form non-circular gaps between segment cross-sections; translating the segments relative to one another in a common direction to contact a shaping surface or surfaces, while maintaining constant gap widths between the segments; joining the segments to form a unitary body by adding filler material to the gaps.
