TL;DR: In this article, wire electrical discharge dressing (WEDD) is used to improve the grinding performance of metal-bonded diamond wheels, and a model to calculate the axial dressing feed rate is proposed.

TL;DR: In this article, a theoretical model to explain the residual stress behavior and reduction with multi-laser beam offset strategy during the LPBF process is presented, and the results of the microstructure from the last mentioned multi laser beam approach, which creates re-melting cracks, which create new defects, are presented and analyzed.

TL;DR: In this article, a system-simulation based universal modeling approach for NVH-based simulation of electric drive is presented. But the main idea is to use commercial FE-tools for model order reduction and implement generic reduced electrodynamic and acoustic models in a system simulation environment.

TL;DR: In this article, the structure and composition evolution of α-Fe2O3 doped alumina granules during calcination were investigated by means of synchrotron X-ray powder diffraction.

TL;DR: In this paper, an innovative CAM-system has been programmed to allow the manufacturing of advanced geometries using a 4-axis laser machine test bench developed by ETH Zurich, which is capable of providing flawless tools with diameters as low as 50 μm and aspect ratios up to 6.
