In the present paper, we compared following diffuse fraction model: Erbs et al. [2], Maxwell [9], Skartveit and Olseth [10], Reindl et al. [11], Perez et al. [12], Boland et al. [13], and BRL [14].
Perez et al. [12] processed a large amount of data to develop two models.

In the HFQ forming process, the blank is first heated to its solution heat treatment (SHT) temperature, so that solute atoms and precipitates dissolve into the primary α-Al matrix; the material is more ductile due to fewer dislocations and fewer obstacles to dislocation movement, and the yield stress is reduced [5].

Contact model proposed by Aerens el al. [8], using to represent wrap around the inside of the tool and the scallop angle due to stepover
Effects of Process Parameters on Forming Forces.
Szekeres et al. [13] further identified the detailed features of the forming force in ISF using the developed tool with force sensors mounted.
Smith et al. [25] reported a simulation time of 24 days for a single point incremental forming process for a truncated cone shape.
Aerens et al. [8] studied the forces in incremental forming of truncated cones with different materials using experimental and statistical analyses.
It was reported that the forces were in good agreement with experimental results from Aerens et al. [8].
