“…The maximum working length (100mm) was achieved for the lowest step size, increasing also the obtainable wall angle of 1° (compared with higher step size selection). Investigating a 65/35 brass, Fritzen et al (2016) investigate the mechanical resistance of a brass alloy of SPIF, using a CNC parallel robotic arm. The authors conclude that for brass, similar to other metals, the forming forces and the occurrence of fracture increase with the blank thickness increasing.…”
