Towards Fracture Prediction in Single Point Incremental Forming [PDF]

Key Engineering Materials, 2013
The stress state in metal forming processes usually implies low values of triaxiality. It is well known that damage models based only on triaxiality fails to capture the damage behavior properly, and recent articles have stressed the effect of the Lode parameter in describing damage.

Emerging Trends in Single Point Incremental Sheet Forming of Lightweight Metals

Metals, 2021
Lightweight materials, such as titanium alloys, magnesium alloys, and aluminium alloys, are characterised by unusual combinations of high strength, corrosion resistance, and low weight. However, some of the grades of these alloys exhibit poor formability

Forming Limit Predictions for Single-Point Incremental Sheet Metal Forming [PDF]

AIP Conference Proceedings, 2007
A characteristic of incremental sheet metal forming is that much higher deformations can be achieved than conventional forming limits. In this paper it is investigated to which extent the highly non‐monotonic strain paths during such a process may be responsible for this high formability. A Marciniak‐Kuczynski (MK) model is used to predict the onset of

Prediction Of The Coefficient Of Friction In The Single Point Incremental Forming Of Truncated Cones From A Grade 2 Titanium Sheet

Tribologia - Finnish Journal of Tribology, 2023
The aim of this paper is to analyze the effect of the process parameters on the coefficient of friction (COF) in the single-point incremental forming process. This investigation may be useful for further FEM analyses where the tool-workpiece contact must

The Analysis of Forming Forces in Single Point Incremental Forming

MATEC Web of Conferences, 2016
Incremental forming is a process to produce sheet metal parts in quick. Because there is no need for dedicated dies and molds, this process is less cost and time spent.

Interaction of Process Parameters, Forming Mechanisms, and Residual Stresses in Single Point Incremental Forming

Metals, 2020
The residual stress state of a sheet metal component manufactured by metal forming has a significant influence on the mechanical properties, and thus determines the time until the component fails, especially for dynamic loads. The origin of the resulting

Single Point Micro Incremental Forming of Miniature Shell Structures

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
This study focuses on single point micro incremental forming (SPMIF) applied to the forming of miniature shell products in meso-scale. For this study, a desk-top type of CNC forming machine was newly constructed as an experimental apparatus.
