Gang Drilling of Square Micro-Holes on Glass Using USM
The industry needs to develop faster and efficient production for the increase in demands of the society, without compromising the cost. Sometimes, gang operations are performed to generate multiple profiles on a workpiece at once to fulfill the demand. On the other hand, ultrasonic machining (USM) is one of the advanced machining processes used to machine brittle materials or ceramics like glass. This paper focuses on the drilling of multiple square micro-holes at a time on glass using USM. Initially, arrays of square micro-rods have been prepared using wire electrical discharge machining (Wire EDM) method. Using these micro-tools/micro-rods, arrays of square micro-holes have been drilled on the glass slides. In addition, the effect of the control parameters on the performance measures has also been observed.
