Abstract
A new removal optimization method called submerged jet polishing (SJP) is
reported. Experiments are conducted to obtain the removal shape. Results of SJP
indicate that a Gaussian shape removal function can be obtained and that the removal
rate is sensitive to variations in the standoff distance. SJP is applied to the
corrective figuring of a BK7 optical glass. The flatness is improved from
photovolatic (PV) 0.066 \lambda to 0.024 \lambda (\lambda=632.8 nm) after three
iterations, and the root mean square (RMS) value is improved from 0.013 \lambda to
0.00395 \lambda. The experimental result indicates that SJP has a capability for
ultra-precision figuring and can be applied in polishing complex-shaped surfaces.
