外文摘要：Jade carries profound cultural significance and occupies an irreplaceable position in human society. This study proposes a magnetorheological finishing (MRF) process for jade to solve problems such as surface damage in traditional jade polishing. The original CNC jade engraving equipment was improved, and a jade MRF process experimental platform was established. Through comparative experiments between MRF process and traditional grinding wheel finishing, results were validated using a scanning electron microscope, confirming that MRF process could avoid surface damage and significantly improve polishing quality. The effects of abrasives and key process parameters, such as finishing gap, feed rate, and spindle speed, on surface quality and finishing efficiency were studied. For Hetian white jade (Ca2Mg5(Si4O11)2(OH)2), it was found that compared to diamond, CeO2, SiC, and ZrO2 abrasives, alumina abrasive yielded better finishing results. After 1 h of polishing, the surface roughness improved from Ra 615 nm to Ra 53.62 nm.
