Abstract: The surface integrity of the machined surface is having a significant impact on the application of the glass and ceramic materials. Surface integrity is of paramount importance to the industries to prevent the loss of useful life of critical components. However, conventional machining processes are unable to fulfill the demands of the present scenario but hybrid machining processes such as rotary ultrasonic drilling process has shown its potential for enhanced surface integrity. Nowadays, researchers are focused on getting superior machined glass quality because of the hardness and esthetic look. Therefore, the authors performed an experimental investigation to estimate the surface roughness while drilling a hole in glass specimen using rotary ultrasonic machining (RUD). It is concluded that the best drilling condition to get the least value of average surface roughness (167.702 nm) is the usage of coolant with 5000 rpm of spindle speed. At 5000 rpm with coolant supply, the cutting force and drilling temperature have been reduced. It is noticed that the least value of drilling temperature is 54.7 �C with a cutting force of 26.65 N. Finally, the improved surface integrity has been achieved noteworthy using RUD process. It would directly enhance the life span of the glass component and increase its functional usage.
