摘要
In the recent past, ultrasonic vibration-assisted single-point incremental forming has gained the attention of the metal forming researchers' interest. Being a latest development, the process is not completely established from the point of view of the underlying mechanism and the effect of the process variables on the formability of the component. The amplitude of vibration and frequency of vibration are two ultrasonic process-specific variables which may affect the formability of the component. In this research work, the effect of amplitude of vibration along with forming feed and step-depth have been studied by performing a groove test on AA3003 aluminum sheet. The FFL for the SPIF process is proposed based on the thickness strain of the tensile testing component. The critical value of amplitude of ultrasonic vibration and ultrasonic intensity is identified demarking the ultrasonic softening and ultrasonic hardening zone.
