Abstract
In this study, it is proposed to analyse the influence of the process parameters on formability of the GI sheet of grade 80GSM and to obtain the condition for maximum formability. The study on incremental sheet metal forming is conducted using multi point incremental forming (MPIF) tool on GI sheet in cold working condition. MPIF offers advantage over single point incremental forming (SPIF) due to its reduced processing time by increasing tool contact with workpiece. The methodology involves using of grid circle method to analyse formability. The procedure utilized was cylindrical forming process and parameters chosen were feed rate, spindle speed and step depth. To analyse the data and to optimize the condition, Taguchi L18 orthogonal array was used as design of experiment (DOE). The research gap involves limited study of forming process using multi point tool and GI sheet as material. Incremental forming provides greater advantage for rapid prototyping. Optimization of process parameters using MPIF tool helps to reduce material wastage and time in forming process.
