Inflatable deployable parabolic space antennas have received increasing attention from researchers due to their remarkable advantages. The authors proposed a process to form a reflective surface with an inverse cutting formation. A number of gores were designed that would form an ideal parabolic surface, flattened sequentially, cut, and then the seams were glued together inversely to form a whole reflector surface. The factors causing deviations from the expected ideal surface, that is, surface errors, were investigated thoroughly. Surface error parameters were carefully defined, such as the root mean squared (RMS) of variations in form accuracy, volume, and area. The influences of the number of gores, the fitting procedures and the number of discrete shapes were comprehensively evaluated. Finally, the effects on the precision of the stressed surface were analyzed with respect to the microgravity of the film, the spray-paint and the support structure. This work should be valuable in the design of inflated space antennas.
