Description
The innovation proposed is a method for the fabrication of a very low cost, very light weight large aperture Al10SiMg aluminum alloy mirror by the combination of three manufacturing processes. 1. Additively manufactured mirror substrates as demonstrated in previous Phase 1 NASA SBIR S2.03-9125 with 0.2 mm contour accuracy. 2. Precision robotic welding of hexagonal on-axis and hexagonal off-axis segments to produce a larger mirror. 3. Large capacity diamond turning can produce any desired mirror aspheric contour to visible tolerances on the monolithic large mirror.
