Abstract: Rotary Ultrasonic Machining process is one of the best-suited advance machining processes for machining nonconductive, hard, brittle and non-metallic materials such as glass, alumina, ceramic, ferrite, quartz, zirconium oxide, ruby, sapphire, beryllium oxide, composites, etc. Soda lime glass has a wide range of application in the field of electronics optics and fluidics. In present work, a setup Rotary Ultrasonic Machining (RUM), and the experimental study of rotary ultrasonic machining (RUM) is performed. From innovative research, it is observed that high MRR, low overcut find out. The analysis helps us to analyze the effect of various input parameters like ultrasonic power (70, 80, 90 %W), spindle (1000 rpm), frequency (21.5, 22.5, 25.5 kHz) and abrasive grit number (30, 46, 60) on MRR which help to enhance the productivity of ultrasonic drilling. Taguchi's orthogonal array designs the experiments, Taguchi L9 orthogonal array for three factor-three level design is selected. Rotary ultrasonic machining is conducted by performing experiments work and optimizes output characteristics individually with rotary ultrasonic machining at 1000 rpm. Taguchi method is an approach to optimize the process parameters and improve the quality of machining components that are manufactured. By the help of graphs, optimum parameter values were obtained, and the confirmation experiments were carried out the Taguchi optimization method.
