Top tips for selecting the right grease
ExxonMobil offers a five-point plan for ensuring that the right grease is selected for each application.
The six trends of Industry 4.0
The path to the fourth Industrial Revolution is not always clear. Many companies and industrial organisations have different views on the precise meaning of Industry 4.0. As a pioneering technology group, Harting has offerings for these rapid developments and, to make them more comprehensible, has grouped them into six recognisable trends.
The differences between guarding standards ISO 14120 and EN 953
Jeremy Procter, a member of standards committees ISO/TC 199/WG 6 (Safety distances and ergonomic aspects) and BSI MCE/3 (Safeguarding of machinery), and Managing Director of Procter Machine Guarding, explains how the new edition of ISO 14120, the international standard for machine guards, differs from the standard it has replaced in Europe, EN 953.
Top 10 factors to consider when selecting linear systems
Bob Love, Business Development Manager at Schaeffler UK, outlines the top 10 factors engineers should consider when specifying linear modules for single and multi-axis handling and positioning systems.
Proven ways to maximise spring life
Spring life is a very important factor to consider in the design and specification process because springs are often vital components within an assembly where failure may lead to significant consequences. Chris Petts at Lee Spring offers the following thoughts on the subject.
Regenerative braking: the road to energy efficiency starts here
Did you know the invention of robots dates back to XVth century? When Leonardo da Vinci explored the idea of the human body as a machine, he came up with a robotic knight – medieval armour designed with gears, wheels, pulleys and cables that allowed it to move its arms and legs. Premature inventions like this one populate the engineering landscape to this day, often when it comes to energy-saving technologies such as regenerative braking. Here, Tony Young, owner director of supply and repair specialist CP Automation, explains how easy it can be to make industrial applications more energy efficient by using regenerative braking.
Virtual and augmented reality in manufacturing
The Oculus Rift, Microsoft HoloLens and even Google Cardboard are a far stretch from the first virtual reality (VR) headset, created in 1968 by computer scientist, Ivan Sutherland. The concoction was called the sword of Damocles and, because of its formidable size and weight, had to be anchored to the ceiling so it didn’t crush the user. Almost 50 years later, we are only now seeing VR and augmented reality (AR) being used in manufacturing environments. Here Leroy Spence, head of sales development at industrial spares supplier EU Automation, looks at how AR and VR are changing the world of manufacturing.
Resistor liquid cooling boosts 3.3kV medium voltage loads
In motor-driven applications like cranes, lifts, hoists and conveyors, air cooled resistors are common, but in medium-voltage, high-power applications liquid cooling wins out. A medium voltage drive running off a 3.3kV supply to turn a 500kW motor will put a severe heating load on the application’s power transistors – hence the need for water cooling, as David Atkins, projects director at Cressall Resistors explains.
