Research on the residual stress of glass ceramic based on rotary ultrasonic drilling

In the process of machining, the glass ceramic is easy to crack and damage, etc. And the residual stress in the machined surface may cause the crack to different extent in the later stage. Some may even affect the performance of the product. The residual stress of rotary ultrasonic drilling and mechanical processing is compared in different machining parameters (spindle speed, feed rate). The effects of processing parameters and methods are researched, in order to reduce the residual stress in the mechanical processing of glass ceramic, and provide guidance for the actual processing.
