Abstract

A novel manufacturing method that is different from the traditional method for off-axis parabola is described. Generally, the figure error between the best-fit sphere and the parabola is many microns. It cannot be measured by high-precision interferometer and traditional hand finishing is not efficient. An advanced technology is introduced and the desired off-axis parabola is produced directly from the best-fit sphere. In this paper, magnetorheological finishing (MRF) technology is employed. The character of polishing spot, the material removal rate and the major manufacturing parameters are described. Fabrication parameters are optimized and the problems of fabricating off-axis parabola in practice are also discussed. A 150 mm diameter part was produced in a period of time in the experimentation with new deterministic polishing method. The final results show that the manufacturing ratio is more obviously improved than the traditional manufacturing method. It is a valid means to fabricate off-axis parabola with high efficiency and high-accuracy.
