Common defects of parts manufactured through single point incremental forming

Abstract

Single point incremental forming is one of the most intensely researched die-less manufacturing process. This process implies the usage of a CNC equipment or a serial robot which deforms a sheet metal with the help of a relatively simple tool that follows an imposed toolpath. As every cold metal forming process, besides the many given advantages it has also some drawbacks. One big drawback in comparison with other cold metal forming processes is the low accuracy of the deformed parts. The aim of this research is to investigate the sheet metal bending mechanism through finite element method analysis. The results shows that the shape of the retaining rings has a big influence over the final geometrical accuracy of the parts manufactured through single point incremental forming.

Influence of Input Parameters on the Coefficient of Friction during Incremental Sheet Forming of Grade 5 Titanium Alloy

“…The computational results showed that moth-flame optimisation, multiverse optimisation and Harris Hawk optimisation provided highly competitive geometry optimisation results. Popp et al (2021) investigated the sheet bending mechanism in the ISF of Al-Cu4PbMgMn aluminium alloy blanks using finite element based analysis. The study showed that the shape of the retaining rings significantly influenced the final geometric accuracy of the parts produced by ISF.…”

Prediction Of The Coefficient Of Friction In The Single Point Incremental Forming Of Truncated Cones From A Grade 2 Titanium Sheet

“…The computational results prove that moth-flame optimization, multiverse optimization and Harris Hawk optimization are very competitive in geometry optimization. Popp et al [30] studied the sheet metal bending mechanism in the SPIF of AlCu4PBMgMN aluminium alloy drawpieces using an FE-based method analysis. It was found that the shape of the retaining rings has a large influence on the final geometrical accuracy of the parts manufactured using SPIF.…”
