On the effective peek application for customized cranio-maxillofacial prostheses: An experimental formability analysis
(Elsevier, 2023)
Single Point Incremental Forming (SPIF) is a dieless and flexible forming technology that allows performing complex shapes and presents a high economic payoff for low production series. In this context, this research ...

Numerical Modelling of Conventional and Incremental Forming of Thin-Walled Tube
(Trans Tech Publications Ltd., 2022)
This study presents a numerical analysis of the tube expansion process by conventional tube-end forming versus single point incremental forming (SPIF) using DEFORM. The work includes the assessment of the strain paths ...

Tube Expansion by Single Point Incremental Forming: An Experimental and Numerical Investigation
(MDPI, 2021-09)
In this paper, we revisit the formability of tube expansion by single point incremental forming to account for the material strain hardening and the non-proportional loading paths that were not taken into consideration ...

Analysis of formability in conventional hole flanging of AA7075-O sheets: punch edge radius effect and limitations of the FLC
(Springer, 2020-03)
Hole flanges are commonly manufactured in mass production by conventional press-working. In an industrial context, the process limits are usually evaluated by means of the Limiting Forming Ratio (LFR), which defines the ...

Analysis of the influence of stress triaxiality on formability of hole-flanging by single-stage SPIF
(Elsevier, 2019-02)
Traditionally the fracture in sheet metal forming is characterized by the fracture forming limit (FFL) curve typically obtained by using conventional Nakajima tests. This curve is implicitly assumed a material property. ...

Stretch-flanging of AA2024-T3 sheet by single-stage SPIF
(Elsevier, 2021-03)
Flanging is a forming process that is commonly used in many high technology industrial applications such as the manufacturing of thin-walled aircraft structures as wing ribs that are formed using rubber-pad forming during ...

On the study of the single-stage hole-flanging process by SPIF
(Elsevier, 2015)
Recent studies show the capability of single-point incremental forming to perform successfully hole-flanging operations using multi-stage strategies. The aim of this work is to investigate the ability of the SPIF process ...

Hole-flanging of AA7075-O sheets: Conventional process versus SPIF
(Elsevier, 2020)
Recently, the research interest in hole-flanging for small and medium-sized batches has turned from conventional press-working to SPIF due to the advantages of incremental forming, such as flexibility and cost ...

Revisiting flangeability in hole-flanging by single-stage incremental forming and conventional process
(PoPuPS (University of LiFge Library), 2021-04)
Recently, hole-flanging by single-stage incremental forming (SPIF) has been proposed as a suitable process to perform hole flanges for small- and medium-sized batches with high flexibility in shape. However, this incremental ...

Analysis of Flangeability by Single-Stage SPIF and Press-Working in AA7075-O Sheet
(American Society of Mechanical Engineers (ASME), 2021-01)
Recently, the research interest of hole-flanging has turned from conventional press-working to single-point incremental forming (SPIF) as a viable process for small- and medium-sized batches. Both technologies have been ...
