Evaluation of the Formability and Dimensional Accuracy Improvement of Ti6Al4V in Warm SPIF Processes
Metals, 2019 Single Point Incremental Forming (SPIF) has great potential as it can be easily implemented and the forming process does not require the use of dies. However, its application to high performance alloys such as Ti6Al4V has not been resolved due to its ...

SPIF of brass alloys: Preliminary studies
AIP Conference Proceedings, 2016This article discusses the preliminary studies of the Single Point Incremental Forming (SPIF) process applied brass alloy Cu-35Zn, with different sheet thicknesses and formed geometries. Despite being a material widely used in industry, with excellent cold formability, there is still no relevant research on this material concerning SPIF. As a result of

Role of Tool Size in Suppressing Defects in SPIF Process
Advanced Materials Research, 2013In the present work, the role of tool radius in suppressing forming defects in SPIF process is investigated. It is shown that a strong correlation exits between tool size and defect appearance. Moreover, there is a certain limit on choosing low limit of tool size for defect-free forming.

Geometry Compensation Methods for Increasing the Accuracy of the SPIF Process
Key Engineering Materials, 2021Despite years of supporting research, commercial use of the Single Point Incremental Forming process remains very limited. The promised flexibility and lack of specific tooling is contradicted by its highly complex deformation mechanics, resulting in a process that is easy to implement but where workpiece accuracy is very difficult to control.

Stabilized-speckle integral field spectroscopy: SPIFS
SPIE Proceedings, 2008We describe an instrument concept and basic feasibility study for a new observational technique which we call Stabilized-sPeckle Integral Field Spectroscopy (SPIFS). SPIFS will enable, under certain observational conditions and constraints, low-to-modest-Strehl diffraction-limited imaging spectroscopy from large ground-based telescopes in the ...

A Dynamic Model for KUKA KR6 in SPIF Processes
Materials Science Forum, 2019The paper presents the development of a dynamic model for the KUKA KR6 robot during single point incremental forming (SPIF) of metal sheets. The dynamic model of the KUKA KR6 robot is created in MATLAB®-SimMechanics. This dynamic model is necessary to verify that the mechanical structure of this low payload industrial robot of 36 Kg capacity can ...

Investigation of Deformation Phenomena in SPIF Using an In-Process DIC Technique
Key Engineering Materials, 2009Single point incremental forming (SPIF) is a promising new production technique in which a metal sheet is formed stepwise by a spherical tool. However, the technique still shows some particularities. It is observed that the final geometry of a SPIF part can deviate significantly from the programmed tool path.
