In order to reduce rotating masses, the Presta joining process is extended to the usage of aluminum shafts. For this purpose, the manufacturing process is modelled using the finite element method and a material model of large strain viscoplasticity to provide a realistic representation of the material behavior even for large deformations. The simulation sequence includes the rolling of the shaft, which causes a local widening of the shaft, and the subsequent joining step, where a cam with an inner profile oriented parallel to the shaft axis is forced onto the widened cam seat.
