Effects of Feed Rates on Deformation Forces and Thickness Distribution in an Ultrasonic-Assisted Incremental Sheet Forming Process
The ultrasonic vibration-assisted incremental sheet forming (UISF) process already indicates its potential in reducing forming forces and increasing the material formability. However, most of previous studies focused on easy-to-deform materials (e.g., Al 1050 and Al 1060 aluminum alloys). It is nece...

| Summary: | The ultrasonic vibration-assisted incremental sheet forming (UISF) process already indicates its potential in reducing forming forces and increasing the material formability. However, most of previous studies focused on easy-to-deform materials (e.g., Al 1050 and Al 1060 aluminum alloys). It is necessary to investigate its effectiveness with harder materials to further understanding this process. The experiments conducted in this work employed the UISF process with a 0.5 mm step depth size, and the high feed rates vary from 1200 mm/min to 2400 mm/min to form truncated cones with a wall angle of 45°, a depth of 20 mm, and thicknesses of 0.5 mm and 1.0 mm. The effect of feed rates on the reduction in component force was experimentally investigated, as well as the distribution of wall thickness after forming process with and without ultrasonic vibration. The results show that ultrasonic vibration not only reduces deformation force but also contributes to more uniform plate thickness distribution. |
