NUMERICAL SIMULATION OF TRUNCATED PYRAMIDAL CUPS OF AA1050 - H18 ALLOY FABRICATED BY SINGLE POINT INCREMENTAL FORMING

The purpose of the present project work was to understand the formability of AA1050 - H18 alloy to fabricate truncated pyramidal 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 proce ss parameters have been optimized using Taguchi techniques. The major process parameters influencing the SPIF of truncated pyramidal cups were tool radius and coefficient of friction.
