Friction at the tool-chip interface during orthogonal nanometric machining

Jean-François Molinari, Guillaume Anciaux, Pedro Romero

Understanding the unfolding of friction between the tool and the generated chip is of fundamental importance to nanometric machining processes. To this end, this paper investigates the influence of tool geometry, lattice orientation, machining velocity and ...

Locomotion studies and modeling of the long-tailed lizard Takydromus sexlineatus

Auke Ijspeert, Konstantinos Karakasiliotis

Morphology is an important factor in locomotion. It may guide the control strategies that an animal or a robot uses for efficient locomotion. In this paper we try to understand the locomotion strategies of a lizard with a distinctive feature, the long-tail ...

Actuator and diagnostic requirements of the ITER Plasma Control System

Jonathan Bryan Lister, Yong Yang

The ITER Plasma Control System (PCS) requires an extensive set of about 50 diagnostic systems to measure the plasma response and about 20 actuators to act on the plasma to carry out its control functions. The specifications and real limitations of the actu ...

Imitation Learning of Motion Coordination in Robots

Elena Gribovskaya

The ease with which humans coordinate all their limbs is fascinating. Such a simplicity is the result of a complex process of motor coordination, i.e. the ability to resolve the biomechanical redundancy in an efficient and repeatable manner. Coordination e ...

Fractional Brownian motion and anomalous diffusion in vibrated granular materials

Daniele Mari, Gérard Gremaud, Alessandro Luigi Sellerio

We propose a new approach to the study of diffusion dynamics in vibrated granular systems. The dynamic of a granular material is mainly defined by dry friction interactions. This type of interaction is difficult to model for a large quantity of particles. ...

Peak and residual strengths of brick masonry spandrels

Katrin Beyer

Unreinforced masonry (URM) walls comprise vertical piers and horizontal spandrels, which together form the lateral load resisting system. Whereas past research yielded significant advances in the understanding of the force-deformation characteristics of ma ...

Damping properties of the nucleus pulposus

Dominique Pioletti, Arne Christian Vogel

Background: The nucleus pulposus is extremely deformable and it is not uncommon to observe strain amplitudes as large as 12.5% in physiological loading conditions. It has been shown that the nucleus pulposus contributes to the damping properties of the int ...

Evaluating the use phase energy requirements of a machine tool system

Paul Xirouchakis

This paper has an energy consumption reduction perspective by considering alternative machining strategies and system components interactions translated into variable and constant power flows with respect to various use phase regimes of a machine tool syst ...

A multi-criteria decision method for sustainability assessment of the use phase of machine tool systems

Paul Xirouchakis, Ian Anthony Stroud, Ioan Oliver Avram

In recent years, going green has become a strategic priority in manufacturing which has evolved from the growing awareness of the need for environmentally friendly processes and products. Recent trends in developing new machining strategies able to support ...
