Study of Process Parameters of Ultrasonic Machining on Borosilicate Glass

The relentless evolution of advanced manufacturing technologies demands the precise machining of high-strength, temperature-resistant (HSTR) materials including borosilicate glass, which are pivotal in aerospace, nuclear, and automotive industries. Modern materials like high-strength metals and ceramics developed to meet advanced industries’ needs are typically strong, hard, and brittle. These materials may not be suitable for traditional machining methods due to the chipping or fracturing of the surface layer or even the whole component, resulting in poor product quality. Ultrasonic machining is one of the most widely used non-traditional machining processes for machining non-conductive, brittle materials. Unlike other processes, ultrasonic machining does not damage the work surface thermally, contributing to the successful performance of these materials in service. The ultrasonic machining process has successfully made holes in borosilicate glass. Power rating and tool feed rate are the most important parameters that have more influence on MRR and overcutting.
