TLDR
In this article, a robotic manipulator has been used to manipulate sheet metal with respect to tool to form steeper wall angle parts in a single stage in incremental sheet metal forming.Abstract:
Incremental sheet metal forming (ISF) is an emerging technology where the sheet is deformed incrementally by a stylus tool using a predefined tool path. Higher formability and process flexibility as compared to conventional forming can be achieved by this process. However, forming steeper wall angle parts in single-stage forming has been a challenging task in ISF. In this work, a robotic manipulator has been used to manipulate sheet metal with respect to tool to form steeper wall angle parts in a single stage. Process parameters have been varied to investigate the fracture limit of the sheet at steep wall angle. Effect of part inclination and part rotation using the designed manipulator on the formability of the sheet has been investigated. Analytical investigation of the effect of parameters on forming force and formability has been discussed and later validated by numerical simulation and experiments. The results show that the formability of the sheet changes by varying these process parameters. Formability can be improved by changing the part inclination and part rotation.read more

The influence of ultrasonic vibration on parts properties during incremental sheet forming
TL;DR: In this article, a series of truncated pyramids were formed with an experimental platform designed for the ultrasonic-assisted incremental sheet forming, and the results showed that the surface micro-hardness of the formed part was reduced since the vibration stress induced by ultrasonic vibration within the material which eliminated the original internal stress.
