The FLC, enhanced fromavbility, and incremental sheet forming [PDF]

, 2009
The FLC is a well known concept in the sheet metal forming world. It is used to map the material’s formability and the make-ability of a product. The FLC is valid only within certain restrictions.

A Comparative Investigation of Conventional and Hammering-Assisted Incremental Sheet Forming Processes for AA1050 H14 Sheets

Metals, 2021
Incremental Sheet Forming (ISF) is emerging as one of the popular dieless forming processes for the small-sized batch production of sheet metal components. However, the parts formed by the ISF process suffer from poor surface finish, geometric inaccuracy,

Research on the Negative Multistage Incremental Forming of Straight-Wall Parts Based on the Extrusion from the Forward and Reverse Side of the Sheet

Metals, 2022
Because the forming area involved in traditional reverse multistage incremental forming is only located inside the model, the sheet-metal thinning rate is relatively large.

Forming Limit Diagram, Void Analysis, Strain Distribution and Surface Roughness for SS430 Sheets During Multipoint Incremental Forming [PDF]

Archives of Metallurgy and Materials, 2018
Single point incremental forming process is a most economical Die-less forming process. The major constraint of it is that it is a time consuming process. In this work, a new attempt was made in incremental forming process using Multipoint tool for SS430
