Abstract

Single Point Incremental Forming (SPIF) is a promising manufacturing technology concerning the production of customized products, low batches or prototyping of ready-to-use parts, given its easy implementation and absence of dedicated tooling. The range of application is wide, covering many materials and virtually unlimited geometries. Indeed, nowadays’ process downsides are more related to high forming times and dimensional inaccuracy. There are many processing parameters that can be optimized to circumvent such problems. In this work, focus is given on the effect of increasing tool feed rate. To this end, a dedicated SPIF machine is employed. After forming steel and aluminum sheets, parameters like forming force, maximum wall angle and formability are assessed for a range of velocities from 1500 to 12,000 mm/min. Parameters like step down or tool diameters are kept constant for a clear comparison. It will be shown how the process can be fastened up without seriously compromising its feasibility.
