Incremental sheet forming parameters and applications: a review

Parâmetros e aplicações de formação de folha incremental: uma revisão

Abstract

The present work introduces a literature review on the Incremental Sheet Forming process application and main parameters. This process is used to manufacture small batches of parts and formed sheets prototypes, as a semi-spherical-tipped tool yields form to a sheet using a pre-defined trajectory and various step-downs (Δz). In this work we describe the Incremental Sheet Forming process variations, application examples, the types of machines used and the diagram characteristics that describe the formed material’s strain limits. The article also presents a detailed study on the influence of the main strength parameters required to execute the process, material formability, surface finishing and final product accuracy.
