Influence of the Blank Initial State on the Quality of the Small Drawn Parts

Abstract:

An optimum blank quality presents the following several benefits on the drawn part quality: it leads to an improved quality of the parts; it prevents some negative phenomena (like: fracture, a uniform distribution of material thickness in the drawn part and reduction of the blank holder force required during the drawing process). In the present work, an analysis was performed concerning the influence of the initial state of blank (microhardness, thickness, surface roughness and topography) on the quality of micro/milli cylindrical drawn parts made from aluminium alloy sheets having the following thicknesses: 0.10 and 0.20 mm.
