Modeling and analysis of the material removal rate for ultrasonic vibration–assisted polishing of optical glass BK7

The emergence of ultrasonic vibration–assisted polishing technology has effectively improved the machining accuracy and efficiency hard brittle materials in modern optical industry; however, material removal mechanism (UVAP) still needs to be further revealed. This paper focuses on glass (BK7), application axial vibration, atomization slurry; model was established. Based analysis relationship between nominal distance d pad actual contact area distribution, prediction profile is realized. In addition, effects different parameters rate (MRR) were analyzed, including force, spindle speed, abrasive particle size, amplitude, feed rate, flow slurry. motion equation particles, trajectory particles slurry simulated, simulation results show that introduction vibration field changes state embedded free particles. new cannot only qualitatively analyze influence process MRR, but also predict depth providing a possibility for deterministic theoretical basis subsequent complex curved surfaces glass.
