A Review of Ultrasonic Assisted Electrolytic In-Process Dressing (UA-ELID)

Abstract

This paper presents previous research work of researchers on electrolytic in-process dressing and its ultrasonic-assisted system variant. This paper also contains information about the ELID system and applications of ultrasonic-assisted ELID. This technique enables continuous dressing of wheels made using metallic bond in the grinding process itself while retaining sharp grits from the super abrasive wheels. An ultrasonic-assisted setup requires an ultrasonic power generator, piezoelectric transducer (PZT), horn assembly. An ultrasonic generator generates ultrasonic pulses, which are supplied to the piezoelectric transducer. The piezoelectric transducer then converts electrical energy to mechanical energy and vibrates either in longitudinal mode or in transverse mode. The horn system then amplifies these vibrations, and amplified vibration is supplied to the grinding tool. The relevance of research papers referred to regarding setup development of ultrasonic-assisted electrolytic in-process dressing, effect of process parameters and modeling of the ultrasonic-assisted ELID process is described in this paper.
