Stabilized-speckle integral field spectroscopy: SPIFS

SPIE Proceedings, 2008
We 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 ...

The SPIF project

1997
This paper introduces the current developments of the SPIF (Systeme de Prototypage a Implantation rapide et Faible cout) project. The goal of SPIF is to provide a low cost environment for quick prototyping of embedded distributed real-time applications. The hardware platform is built with reusable, standard off-the-shelf components. SPIF is the name of

Experimental failure analysis in polycarbonate sheet deformed by spif

Journal of Manufacturing Processes, 2021
Abstract The analysis of polymeric sheet materials deformed by means of incremental sheet forming technologies has recently caught the attention of a number of research groups of the materials forming community. The versatility of the process, which allow manufacturing customised sheet components without the need of dedicated tools or dies, as well ...

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.

Effect of manufacturing process on mechanical properties of polyetheretherketone (PEEK) cranial implants produced by single-point incremental forming (SPIF)

Materials Research Proceedings
. Polyetheretherketone (PEEK) is one of the most commonly used materials for cranioplasty due to its biocompatibility, relatively high strength, and light weight.

Roughness Test of Aluminum A5052 before and after Forming by SPIF Process

Key Engineering Materials, 2023
Single point incremental forming process, which is also known as SPIF, that forms from one direction. SPIF process was used for milling an aluminum metallic sheet. In this paper, an aluminum (A5052) sheet was formed in a conical shape by the SPIF process.

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.
