“…This standard is ISO 14649 [4] and ISO 10303 AP 238 [5]. The STEP-NC AP238 standard is the result of a more fifteen years international effort to replace G code (ISO 6983 standard) with a modern associative language that connects the CAD design data used to determine the machining requirements for an operation with the CAM process data that solves those requirements [6].…”

“…Based on the geometry two choices existed for a die-to-specimen ratio: either the die is smaller than the specimen (to which a kind of gouging effect would be expected at the edges of the die), or the die is bigger than the specimen (to which the edge of the specimen is pinched between die and punch). These two issues are not normally seen in can ironing as the cylindrical geometry and tooling naturally provides no edge [116]. Since any video capture metrology required a view of ironing from the side, the design progressed with a wider die than specimen.…”

This project was undertaken to explore the viability of manufacturing polymer-coated cans using current drawing-wall-ironing methods, and centres around exploring polymer-coated alternatives to lacquered food and beverage cans. A full process FEA model was developed in Abaqus, and a polymer coating characterisation was attempted via tensile and compressive tests of available PET. As an alternative, the polymer was modelled as a force/over-closure con-tact deﬁnition in ﬁnite element analysis models, using force data derived from existing polymer data. The contact deﬁnition demonstrated an effective alter-native to modelling a ﬁnite element meshed polymer layer but needed opti-mising to match physical results. A tensile test machine rig was designed and manufactured capable of ironing strip metal specimens for otherwise unavail-able ironing metrology. The rig was calibrated using uncoated steel, then used to gain data on force and resulting geometry for polymer coated steel during and after ironing. Rig data was used in a ﬁnite element analysis automated feedback loop to optimise the force/over-closure and friction coefﬁcients for the contact deﬁnition. Finally, a full-process drawing-wall-ironing simulation on polymer coated steel was implemented in a design of experiments study, which mapped the previously unexplored design space. The most signiﬁcant parameters in resulting can geometry were the percentage of redraw and iron-ing during the respective forming phases, as well as the redraw radius. De-creasing the diameter of both redraw and ironing tooling rings resulted in a longer and thinner can, as did decreasing the redraw radius. Whilst not an ex-haustive study, the project ultimately demonstrated the viability of modelling polymer-coatings using contact deﬁnitions in ﬁnite element analysis and paves the way for further study into the polymer-coated steel can.
