Review on the influence of process parameters in incremental sheet forming

Incremental sheet forming (ISF) is a relatively new flexible forming process. ISF has excellent adaptability to conventional milling machines and requires minimum use of complex tooling, dies and forming press, which makes the process cost-effective and easy to automate for various applications. In the past two decades, extensive research on ISF has resulted in significant advances being made in fundamental understanding and development of new processing and tooling solutions. However, ISF has yet to be fully implemented to mainstream high-value manufacturing industries due to a number of technical challenges, all of which are directly related to ISF process parameters. This paper aims to provide a detailed review of the current state-of-the-art of ISF processes in terms of its technological capabilities and specific limitations with discussions on the ISF process parameters and their effects on ISF processes. Particular attention is given to the ISF process parameters on the formability, deformation and failure mechanics, springback and accuracy and surface roughness. This leads to a number of recommendations that are considered essential for future research effort

Sull'età degli zirconi di Campanella di Altissimo (Valle del Chiampo, Lessini Orientali)

A single crystal of zircon from the basal sequence of Tertiary lavas outcropping at Campanella di Altissimo (Vicenza) was dated by the U-Pb radiometric method, applying the Sensitive High mass Resolution Ion MicroProbe (SHRIMP) tecnique. An age of 44.9+/-2.8 Ma was obteined, as a mean, on six analysed points. As some distinctive features (e.g. Th/U ratio, cathodoluminescence image) indicated that the zircon is of magmatic origin, the mineral age corresponds to that of the host rock. It is therefore possible to attribute the initial basaltic emission, produced by the volcanic activity in the Veneto area, to the Lutetian
