Abstract

Shearing of bulk material is a cost efficient method of producing billets for subsequent forging operations. The procedure of rod shearing is characterised by high billet output quantities without metal removal. This technique is widely used in industrial processing of steel materials. Aluminium billets however, are mostly produced by sawing, causing higher manufacturing costs due to comparably low output. The aim of this paper is an enhancement of sheared aluminium billet quality in order to fulfil industrial standards required for further forging operations. To enhance the quality of sheared aluminium billets, the shearing process parameter clearance (distance between the blades) was varied to create billets of four different aluminium alloys, as EN AW 5754 (UNS A95754), EN AW 5083 (UNS A95083), EN AW 6082 (UNS A96082) and EN AW 7075 (UNS A97075) in different conditions. The quality of sheared billets is assessed by analysing inclination angle, waviness and surface defects of the sheared parts with 3D-measurement. In the investigation, it can be shown that the tensile strength of the investigated alloys influences the billet surfaces. High tensile strength results in positive billet quality. Further, small clearances show best results concerning inclination angles, while higher clearances result in decreased waviness.
