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 indus

Due to a complex load spectrum of mechanical, thermal and tribochemical loads, hot forging tools are subject to increased wear. This results in cost-intensive reworking and possibly unscheduled machine downtimes. To reduce wear, research is currently

Hot forging is an effective production method producing safety relevant parts with excellent mechanical properties. The economic efficiency directly depends on the occurring wear of the tools, which limits service lifetime. Several approaches of the

Shearing is particular economic for the production of forging raw parts but not implemented as an industrial production process because of insufficient shear qualities. To take advantage of the shearing of aluminium alloys, an experimental shear tool

Tools used in hot forging operations are subjected to high wear during processing due to complex load conditions with high temperatures and mechanical loads. The resulting abridged service lifetime of the dies highly restricts the cost-effectiveness

Dies in hot forging operations are subjected to a complex load combination consisting of thermal, mechanical and tribological loads. Therefore, hot forging dies exhibit short service life in comparison to other forming operations. An extension of too
