Ultrasonic vibration assisted machining with harder abrasives than the material to be machined can improve the quality of machined surface and manufacturing efficiency. Therefore, we integrated ultrasonic vibration (UV) into a recently developed technique chemo-mechanical bound-abrasive polishing in anticipation of further increasing the material removal rate (MRR) and/or surface roughness. The preliminary results indicate that ultrasonic vibration assisted chemo-mechanical bound-abrasive polishing can lead to increased material removal rate of manufactured optics while leaving the surface roughness comparable to conventional chemo-mechanical bound-abrasive polishing. The great MRR is attributed to the superiority of UV-assisted chemo-mechanical bound-abrasive polishing in discharging resultant swarf during machining.
