Improved SPIF performance through dynamic local heating

International Journal of Machine Tools and Manufacture, 2008
Abstract The limited accuracy of the single point incremental forming process [J. Jeswiet, F. Micari, G. Hirt, A. Bramley, J. Duflou, J. Allwood, Asymmetric single point incremental forming of sheet metal, Annals of CIRP 54(2) (2005) 623–650] has been identified as its major deficiency [J.M. Allwood, G.F. King, J.

Deviations between FE Simulation and Experiments in the SPIF Process

Key Engineering Materials, 2011
Single Point Incremental Forming (SPIF) is a modern and flexible alternative to traditional forming techniques. It thanks its flexibility to the fact that it does not require a dedicated tool set to operate. Numerical simulation of the SPIF process requires an accurate FE model.

Use of TPIF or SPIF for Prototype Productions: an Actual Case

AIP Conference Proceedings, 2007
The present research deals with sheet incremental forming (SIF), a recently developed technique characterized by high flexibility, reduced production times and costs. This is ideal when low volume batches or customized parts or prototypes have to be manufactured.

CAD/CAM Strategies for a Parallel Kinematics SPIF Machine

Key Engineering Materials, 2013
Single point incremental forming has attracted the interest of researchers in the last decade for the production of prototypes and small batch production of sheet-based parts [1, 2]. This technique allows the manufacture of parts without using expensive die sets.

SPIFS performance simulations: achieving diffraction-limited spatial resolutions for spectroscopy

SPIE Proceedings, 2008
We present the results of performance simulations characterizing the Stabilized sPeckle Integral Field Spectrograph (SPIFS). Our simulations of images distorted by Kolmogorov atmospheric turbulence confirm that stabilization of the single brightest speckle via a fast steering mirror (FSM) produces near-diffraction-limited spatial resolution for the red

Optimization lubrication and speed in SPIF processes

2018
Com a constante competitividade da indústria, existe a necessidade de criar novos métodos e processos que colmatem lacunas dos já existentes, assim como procurar soluções com rendimentos superiores, tanto quantitativamente como qualitativamente. A estampagem incremental surge aliada à dificuldade de produção de protótipos funcionais e reais.
