Abstract
Incremental sheet forming (ISF) process show a great potential in the manufacturing of small series production or prototype development parts. One of the sheet metal forming process, where the contact between punch and metal sheet is in a single point, is known as single point incremental forming (SPIF). The part is manufacture with a simple tool, known as punch, that performs a series of combined movements on the vertically and horizontally directions. The paper introduces a study regarding the design rules and process modelling of this unconventional process, by means of a KUKA KR210-2 industrial robot as technological equipment able to control the correlated movement of the punch. Supplementary, the design of the experimental layout, the process simulations and the singularity problems are considered.

Due to the advantages that it offers in analogy with traditional sheet metal forming processes, in terms of lower production cost and shorter manufacturing time of the parts, mainly due to the fact that the forming process is achieved through a simple and relatively inexpensive universal tool [1], known as the punch, it can be stated that Incremental sheet forming (ISF) process allow a high degree of flexibility
Summary
Process flexibility is a critical design consideration in complex product supply chains facing an uncertain demand. Within the manufacturing processes of the sheet metal forming, using a conventional forming process means expensive dies, complicated forming tools and less flexibility. The challenge was to find a cost-effective flexible configuration that could meet industry demands regarding changing requirements in a timely and cost-effective manner. Due to the advantages that it offers in analogy with traditional sheet metal forming processes, in terms of lower production cost and shorter manufacturing time of the parts, mainly due to the fact that the forming process is achieved through a simple and relatively inexpensive universal tool [1], known as the punch, it can be stated that ISF process allow a high degree of flexibility
