Burr avoidance in flash-free forging of aluminum under consideration of industry-related process parameters and variation of tool-integrated sealing concepts

The use of flash-free forging in the aluminium forging industry is significantly complicated by the formation of burr, which limits the advantages on the process side and extends the process chain through machining finishing.

The research objective is to avoid the burr by tool-integrated sealing concepts and to predict the formation of burr taking into account industry-related process parameters in the flash-less forging of aluminium. In cooperation with Otto Fuchs KG, a systematic investigation of the process conditions in an examination tool with four universally valid burr cases will be carried out and subsequently a sealing concept will be developed. For this purpose, the influence of the sealing concepts on the sealing effect is identified in experimental investigations consisting of functionality and wear investigations.

Based on the findings, an extended forecast model for burr can be developed.
