To enhance milling performance on ISO S materials, cutting tool and tooling system specialist, SandvikCoromantis introducing a series of end mills featuring geometries and grades. TheCoroMillPluraHFS (High-Feed Side milling) ISO S cutters deliver reliable and productive results onworkpiecesmade from titanium and nickel-based alloys, bringing benefits to both aerospace engine and frame applications.

Researchers have shown how the principles of general relativity open the door to novel electronic applications such as a three-dimensional electron lens and electronic invisibility devices. In a study funded by the Academy of Finland, Aalto University researchers Alex Westström and Teemu Ojanen propose a method to go beyond special relativity and simulate Einstein's theory of general relativity in inhomogeneous Weyl semimetals.

If you have ever watched television in anything but total darkness or used a computer while sitting underneath overhead lighting or near a window, you have experienced a major nuisance of modern display screens: glare. Most of today’s electronics devices are equipped with glass or plastic covers for protection against dust, moisture, and other environmental contaminants, but light reflection from these surfaces can make information displaye...

Shaping nanometric gold particles-of the size of millionths of a millimeter-to improve their properties in biomedicine and photonics has been made possible thanks to a special laser system in a work carried out at the Universidad Complutense de Madrid (UCM) and now published inScience.

There is a current project underway at the Centre for Fine Print Research (CFPR) which is looking at 3D printing from a totally different angle - where the emphasis is placed on meaningful expression, rather than the accurate reproduction of digital data, and at the centre of the project lies a flexible Mitsubishi Electric MELFA RV-7FLM articulated arm industrial robot.

Meshes made from fibres with nanometer-scale diameters have a wide range of potential applications, including tissue engineering, water filtration, solar cells, and even body armour. But their commercialisation has been hampered by inefficient manufacturing techniques.

Due to a strong demand for reliable maching solutions in the aerospace industry, cutting tool and tooling system specialist Sandvik Coromant has launched new tapping and thread millung tools forISO S materials (titanium and nickel-based alloys).The products have been purpose designed to deliver process security on high value components, such as engine casings, thus providing reductions in scrap rates and machine downtime.

If a robot is sent to disable a roadside bomb — or delicately handle an egg while cooking you an omelet — it needs to be able to sense when objects are slipping out of its grasp.Yet to date it’s been difficult or impossible for most robotic and prosthetic hands to accurately sense the vibrations and shear forces that occur, for example, when a finger is sliding along a tabletop or when an object begins to fall.

Improving the design of drills capable of excavating deep holes should increase their performance and longevity. Scientists from A*STAR develop a computational model that can determine the ideal drill design, achieving significant savings.In designing a drill, a crucial consideration is the effective removal of material, known as chips. A standard drill bit, the part of the drill that excavates the hole, removes chips by having a spiral shape tha...

When light is confined between two partially reflecting mirrors and amplified by some material in between them, the resulting beam can be extremely bright and of a single colour. This is the working principle of the laser, a tool used in all areas of modern life from the DVD player to the operating theatre.
