Abstract

Incremental Sheet Forming (ISF) is gaining importance because of its flexibility to form customized/low volume sheet metal parts. Out of different variants of ISF, Double Sided Incremental Forming (DSIF) is most flexible variant which uses two tools, one to form the geometry and the other to provide local support. Complex geometries with features on both sides of sheet can be formed in single setup by changing the roles of forming and supporting tools based on the geometrical characteristics. This article presents the evolution of DSIF process, machines, methodologies and strategies to form complex geometries and their prediction. A multi-stage methodology is attempted to enhance the accuracy of large components is presented. Results show that the accuracy of a 250 mm × 250 mm size conical component is enhanced by 50% (maximum error reduced from 2.9 mm to 1.4 mm) using two-stage forming.

Summary

Introduction

Incremental Sheet Forming (ISF) is gaining importance because of its flexibility to form customized/low volume sheet metal parts [1, 2, 3, 4, 5]. Double sided incremental forming is the most flexible variant of incremental sheet forming. It uses two independently controlled tools, one on either side of sheet, to form the geometry. One tool will be forming the geometry while the other provides local support that enhances the accuracy of components. The role of tools (forming or supporting) can be changed to form complex three-dimensional parts having features on both sides of sheet and/or multiple features. A multi-stage methodology is attempted to enhance the accuracy of large components formed using DSIF. While forming large components, compliance of scaled-up DSIF machines results in either loss of support tool contact or squeezing of sheet material.
