TL;DR: The main influence on process efficiency in metal cutting can be related to the machining parameters, while performance also depends on the material behavior such as strain rate, machining temperature and cutting forces as discussed by the authors.

TL;DR: In this article, the authors present three groups of Smart Materials: piezoceramics, shape memory alloys and dielectric elastomers and their specific characteristics, including physical working principle, their mechanical behavior, the actuation and sensing properties.

TL;DR: In this article, an ultrasonic vibration assisted milling (UVAM) system was implemented in a high precision machining center and initial experimental investigations were carried out, and a surface simulation tool was developed and used for the structure design and modelling, which predicts a virtual micro structure using the relevant parameters.

TL;DR: In this article, the authors present results of the first systematic assessment of the biological transformation of the German manufacturing industry and identify ten fields of action for setting the course for a sustainable industrial value creation.

TL;DR: Calculated resonance frequencies are generally lower than measured values, which indicates, that numerical models lack stiffness in FE modeling of pelvic bone.
