The paper reports a newly developed optical polishing process by means of ultrasonic-magnetorheological compound finishing (UMC finishing). The machining principle and the experimental procedure of UMC finishing are introduced in the paper for the first time. Experiments are carried out to study the material removal property in UMC finishing of optical glass. The polishing head in UMC finishing is adjusted for different positions to form different angles between its own spindle axis and that of t workpiece during polishing. Experimental results show that the shape of material removal profile changes with the angle. The shape of material removal profile of UMC finishing when the polishing head is oblique is more desirable than the ring-shaped one when the polishing head is vertical. Furthermore, the surface roughness is also analyzed.
