Single point incremental sheet metal forming


Oct 15, 2018 · What is Incremental Sheet Forming? Incremental sheet forming is a dieless sheet forming process which involves deforming sheet material little-by-little in progressive layers. Force is applied to the sheet material using a single point sphere. Incremental forming is an alternative to deep drawing and can be used to make similar parts. Building on previous and current work, this research utilizes Single Point Incremental Forming (SPIF) and Dual-Sided Incremental Forming (DSIF) to produce mass customized, double-curved (both positive and negative Gaussian curvature), three-dimensional forms from sheet metal.

Incremental sheet forming is an inexpensive technique for sheet metal prototyping and small batch works. The final product is formed by a series of incremental deformations. The tool path is programmed for a CNC-machine or a robot and the desired shape is formed without the need of a forming die. Single-point incremental forming (SPIF) is a new sheet-metal-forming process with a high-potential economic pay-off for rapid prototyping applications and for small-quantity production. The basic components in the SPIF process are presented in Fig. 1: sheet metal blank, blank holder, backing plate, and rotating single-point forming tool.
