Top tips for choosing the right harmonic filter
In 1976, it was discovered that the bacteria causing Legionnaires disease, an atypical strain of pneumonia, had always been present in water, but it was the precise temperature of the water in heating, ventilation and air conditioning systems that facilitated the bacteria’s maximum reproduction levels. This is just one example of the unintended consequences of technology. A similar and more recent story comes from the world of industry and features the growing problem of harmonic currents and utility level voltage distortion, as a result an increasing number of non-linear loads in industrial and commercial environments. Here, John Mitchell, global business development manager of CP Automation, shares his top tips for companies that want to commission or replace harmonic filters.

Flexible manufacturing through automated engineering
Science fiction has taught us to fear things that are out of our control. Whether its alien invaders from another planet, highly-evolved apes or artificially intelligent robots, sci-fi culture is built on humanity’s fear of being second in command. With that being said, automated equipment and robotics are the basis of any smart factory, meaning that to stay competitive, manufacturers must learn to embrace this technology. Here, Jonathan Wilkins, marketing director of EU Automation, discusses automated engineering.

Flexible machines to produce at batch size 1
Lenze as an automation provider view Industry 4.0 is simply another phase in the increasing automation that has been underway for many years. Automation is being consistently advanced by digitisation, networking and the use of new communication systems. This progress allows automation providers to provide smart systems that satisfy the changing demands of makers of machinery who in turn must fulfil the market needs. One of these demands is the growing individualisation of products. A car maker no longer simply offers a wide range of models, nowadays buyers can select a mix of options that is only produced once for their car. This is batch size 1.

Using Ethernet alongside a dedicated motion network
Open communications are an ever-growing requirement and with industrial Ethernet offering speeds high enough for even demanding deterministic motion control applications, is there still a role for dedicated motion networks? Mitsubishi Electric’s Product Manager Barry Weller argues that there is…

Oxy-fuel safety: it’s everyone’s responsibility
Oxy-fuel processes such as heating, cutting, brazing and welding create a potential danger from flames, sparks and intense heat. Despite these hazards, millions of people work accident free. By design, manufacturers build safe equipment. This decreases the likelihood of a potential incident. However, good oxy-fuel operators know that their own safety, as well as the safety of those around them, depends on proper and responsible use of oxy-fuel equipment. This article by Paul Woodford, Global Product Manager, ESAB, provides guidelines for proper set-up and shutdown procedures, as well as technical and safety principles.

11 challenges machine designers face
Machine design has seen rapid developments in recent years, especially with increasing popularity of smart machines. These advances include the development of intelligent components, better communication between operator and machine, automated machine decisions and more. Smart machines are more efficient, with interconnected components expanding the capabilities of machines to communicate with and respond to their surroundings like never before. By Evan Artis, Global product manager, Eaton Electronic Controls and Software
