The feasibility of using modern computers in manufacturing has evolved an era in the development of several new sheet metal forming process. The concept of profile forming technique has been investigated for production of sheet metal components. Profile forming is a very promising technology to manufacture sheet metal producs by CNC controlled movement with simple forming tool. Profile forming was developed as a flexible, alternative manufacturing method to effectively prototype stampings and produce in small lots. Cylindrical Cup is formed on Aluminium sheet of grade Al 3003 (O) without using punch and die. Formability of material, maximum wall angle, Surface roughness, thinning of sheet and Microstructural characteristics of Aluminium sheet are studied.

Cold Metal

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.

To improve sheet metal forming process simulation using finite element method, there is a need to incorporate an appropriate constitutive equation capable of describing the Bauschinger effect and the so-called cyclic transient, derived from a near to actual sheet metal forming process testing tool. A cyclic loading tool has been developed to test and record the characteristics of sheet metal deformation by investigating the Bauschinger effect factors (BEF) and cyclic hardening behaviour. Experimental investigation conducted on low carbon steel and stainless steel demonstrates that the tool is able to record sheet metal behaviour under cyclic loading. The results are analysed for signs of the Bauschinger effect and cyclic hardening effect. It was found that the Bauschinger effect does occur during bending and unbending loadings in sheet metal forming process.
