Experimental Investigation on the Single Point Incremental Forming of AlMn1Mg1 Foils using Flat End Tools

Single Point Incremental Forming (SPIF) is one of the main and most used variants of Incremental Sheet Forming (ISF), a flexible rapid prototyping technique in the sheet metal sector. In this paper, the effect of flat end tools on SPIF with variable wall angle geometry was studied under different process parameters. Experiments on AlMn1Mg1 sheets with 0.22 mm initial thickness are carried out by a CNC Milling Machine. Geometry measurements of the formed parts carried out on a coordinate measuring machine (CMM) are also presented.
