Ultrasonic vibration assisted single point incremental forming (UVaSPIF) is based on localized plastic deformation in a sheet metal blank. It consists to deform gradually and locally the sheet metal using vibrating hemispherical-head tool controlled by a CNC milling machine. The ultrasonic excitation of forming tool reduces the vertical component of forming force. In addition, application of ul...

Abstract Today the topic of incremental sheet forming (ISF) is one most active areas metal research. ISF can be an essential alternative to conventional for prototypes or non-mass products. Single point (SPIF) innovative and widely used fields in with potential form The formed components by SPIF lack geometric accuracy, which obstacles that prevents from being adopted as a process industry. Pil...

In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

BACKGROUND Viable embryos secrete preimplantation factor (PIF), a peptide that has autocrine effects where levels correlate with cultured embryos development. sPIF (PIF synthetic analog) promotes implantation by regulating decidual-cells immunity, adhesion, apoptosis and enhances trophoblastic cell invasion. Herein sPIF priming effects on non-decidualized endometrium and decidualized-stroma are...

This paper introduces the current developments of the SPIF (Système de Prototypage à Implantation rapide et Faible coût) 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 the testbed itself, a mobile autonomous ro...
