Analyzing and improving surface texture by dual-rotation magnetorheological finishing

- Surface texture models for raster path and spiral path are established.
- DRMRF is presented and custom made setup is developed.
- The distributions of groove angles in common MRF and DRMRF are revealed.
- A quantitative evaluation is proposed to reveal the irrelevance of groove angles.
- Directional texture is suppressed and surface roughness is decreased by DRMRF.
