Implementing Incremental Sheet Metal Forming on a CNC Machining Centre

Abstract

Translate Article

Incremental Sheet Forming (ISF) process emerges as an alternative to classic shaping processes. Two variants of the IS process are used: negative forming or SPIF (Single Point Incremental Forming), in which it is not necessary using a die and positive forming or TPIF (Two Point Incremental Forming) ISF is usually performed on specifically designed machines controlled by CNC or in retrofitted CNC milling machines However, in the most of cases, the possibility of combining milling and ISF is not considered This paper is focused on a study about the implementation of ISF process in a CNC machining center through the specifi design of the clamping tools. So, it is not necessary to retrofit the machining center and it is possible to think abou combining both processes in multitask operations.
