Abstract: The purpose of the present project work was to understand the formability of AA1100-H18 alloy to fabricate conical cups using single point incremental forming (SPIF) process. The finite element analysis has been carried out to model the single point incremental forming process using ABAQUS software code. The process parameters of SPIF were sheet thickness, step depth, tool radius and coefficient of friction. The process parameters have been optimized using Taguchi techniques. The major process parameters influencing the SPIF of pyramidal cups were sheet thickness and step depth of incremental forming process.
