Abstract
Single point incremental forming (SPIF) is highly flexible sheet metal forming process used for small quantity production and new product development. The product with high strength, good surface finish, and higher formability has paramount importance in industrial and marine applications. SPIF has been carried out on AA5052-H32 aluminum alloy which has high strength and difficulty in the conventional forming process. The response characteristics such as surface roughness \(({R}_{\mathrm{a}})\) and maximum forming angle \((\varnothing _{\mathrm{max}})\) were evaluated by considering the independent process parameters such as spindle speed, table feed rate, step depth, tool diameter and sheet thickness through the design of experiments. The step depth and sheet thickness are the most influencing parameters for average surface roughness and maximum forming angle, respectively. It is found that neither the surface roughness nor the forming angle of formed sheets feels the effects of spindle speed significantly. An empirical relation has been formulated, and experiments were carried out to verify the reliability of the developed regression model.
