Aspherizing with MRF
- MRF can generate high removal rates
- ~30 microns / min !
- > 0.5 mm3/min VRR
- No need to grind and prepolish asphere
- No special equipment is needed
- No Mid-spatial frequency (MSF) residuals often generated by this equipment
- Starting from best-fit sphere is "easy" & "cheap"
- D11 & large wheel provides ability to create large diameter precision asphere without aspheric grinding and pre-polishing equipment
- Residual error shown is after one aspherization run, and the part is now ready for figure correction if higher precision is required
