Abstract

This article presents the design and implementation of ultrasonic inverter for use with a drilling machine, in order to compare the material penetration efficiency between non-ultrasonic and ultrasonic penetration.  In the design and construction of an ultrasonic inverter, the 500 V 20 A power MOSFET was used in conjunction with bridge rectifier and switching transformer.  The proposed ultrasonic inverter could drive a 25 kHz, 40 kHz, 60 kHz, 100 kHz and 120 kHz ultrasonic wave with electric power up to 1.1 kW.  It was assembled into a drilling machine and tested the penetration with 4 sample materials, 1 mm. steel sheet, 1.5 mm. stainless sheet,           1 mm. aluminum sheet and 2 mm. acrylic sheet.  The results showed that ultrasonic penetration was faster than non-ultrasonic penetration in all types of sample materials. The time spent in drilling from ascending order was 25 kHz, 40 kHz, 60 kHz, 100 kHz, 120 kHz, and without ultrasonic, respectively
