Abstract
The current world’s economical crisis raised the necessity from the industry to produce components cheaper and faster. In this sense, the importance of smart manufacturing techniques, proper articulation between CAD/CAM techniques and integrated design and assessment becomes critical. The Single Point Incremental Forming (SPIF) process represents a breakpoint with traditional forming processes, and possibly a new era in the small batches production or customized parts, being already used by automotive industry for light components. While classical stamping processes need a punch, a die, a holder and a press, in the SPIF process the final geometry is achieved incrementally through the action of a punch with a spherical head. Since the blank is clamped at the edges, there is no need to employ a die with the shape of the final part. However, this process must be further improved in terms of speed and dimensional accuracy. Because the process is cheap and easy to implement, it is currently the subject of intensive experimental and numerical research, but yet not deeply understood. This chapter gives an overview on the techniques currently being employed to optimize the process feasibility.
