The research team led by Norberto López de La Calle at the Department of Mechanical Engineering at the University of the Basque Country, have designed a new model for optimising the high-speed, 3- or 5- axis milling of complex parts. One of the objectives in this field has been the development of a methodology for the a priori estimation of errors due to flexion of the milling-machine housing system given that some errors, induced by cutting forces, lead to non-compliance with the tolerances of certain applications such as plastic or aluminium injection moulds, precision matrixes and the and the teeth of turbines and compressors.
Now there is available a module that operates with CAM and enables the selection of those milling trajectories, whether in 3- or 5-axes, that minimise the force producing the error. The final result is a saving in milling time and greater added value of the manufactured tools.
The value of this field of research has been tested with applications in a number of moulding and matrix companies.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
