VALIDATION OF SINGLE POINT INCREMENTAL FO RMING PROCESS FOR DEEP DRAWN PYRAMIDAL CUPS USING EXPERIMENTAL GRID - BASED DEFORMATION

The use of finite element analysis in manufacturing has enabled the development of several new sheet metal forming processes. Recent advances have enabled th e localized deformation to be accurately controlled using CNC technology. Single point i ncremental f orming has the potential to revolutionize sheet metal forming, making it accessible to all levels of manufacturing. This paper describes the validation of single point increment forming of pyramidal cups with the experimental grid - based deformation. The present investigation confirms that the FLD is sensitive to strain path of aluminum alloy 2004.
