Evaluation of forming forces in ultrasonic incremental sheet metal forming

Abstract: In this paper, a new type of sheet metal forming technology using ultrasonic vibration applied to SPIF (single point incremental forming) process is presented. Forming force during forming process can induce fracture and affect accuracy of the sheet metal. Design of ultrasonic sheet metal forming equipment can be based on this study, which takes into account magnitude and changing law of the forming force. ABAQUS finite element software was used to simulate and analyze influence of different frequencies and am… Show more

“…Hence, manufacturing of small batch size products and prototypes is not very economical using conventional forming processes in sheet metal forming. Multi-variety components in small batches can be manufactured at low cost with singlepoint incremental forming (SPIF) technology, which prevents limitations of traditional sheet metal forming processes [2]. SPIF is more suitable for the batch type and prototype production due to economical tooling cost, shorter lead time and ability to form nonsymmetrical geometries without using expensive dies for manufacturing complex components of sheet metal [3,4].…”

“…To quantitatively study the influence of the frequency and amplitude on the radial accuracy, a stepless frequency modulation ultrasonic generator was selected as the vibration generator. Experiments have been conducted to [24]. The influence of vibration parameters on the accuracy was studied experimentally when the tool head diameter was 8 mm, the layer spacing was 1 mm, the sheet thickness was 0.8 mm, and the forming angle was 50°.…”
