✦ Synopsis

Deep drawing is one of the most common sheet-metal working processes and is used to make different items: automotive components, household goods, gas bottles, etc. The theoretical studies on this process are mostly related to axisymmetrical bodies, i.e., bodies that are geometrically symmetrical with respect to any diameter, are symmetrically loaded and have symmetrical constraints. When items of a more complex shape have to be produced, the process and its optimisation depend only on the operator's expertise. The present article reports a study made on non-symmetrical bodies. In particular, the effects are considered of some technological parameters, such as strain rate, type of lubricant, die-punch clearance and sheet-metal thickness, on drawing force and deformation, when producing mess tins.
