EVALUATION OF EFFECT OF PARAMETER ON SINGLE POINT INCREMENTAL FORMING OF TITANIUM

Abstract

Single Point Incremental Forming (SPIF) has emerged as a promising technique for shaping complex geometries in various materials. This study investigates the influence of process parameters, specifically step size and tool diameter, on the SPIF of titanium sheets. The experiment comprises three different step sizes (0.2, 0.4, and 0.6 mm) and three tool diameters (6, 10, and 14 mm), applied to titanium sheets. The research focuses on evaluating the impact of these parameters on three crucial aspects of SPIF: thickness reduction, fracture depth, and forming angle in the fracture zone. Through a series of experiments, the relationship between step size, tool diameter, and these performance indicators is thoroughly examined. Results indicate that smaller step sizes lead to higher thickness reductions and more precise forming angles in the fracture region and smaller tool diameters also increased fracture depths. Understanding the interplay between these parameters is vital for optimizing SPIF processes in titanium sheet forming applications, offering insights for enhanced production efficiency and quality in industries relying on advanced forming techniques. The CNC forming process took about 10 hours.
