A quick guide to extension springs
Lee Spring extension springs – otherwise known as tension springs – are useful for many operations in vehicle applications and elsewhere, for example as returns on engine controls, also farm machinery, horse boxes, caravans, trampolines, garage doors, medical devices, toys, washing machines/white goods, and in the construction industry. They are characterised by a loop or hook on either end which is connected to other components giving them extra strength and manoeuvrability.

How to simplify industrial process automation using IO-Link
Industry 4.0 continues to gather pace as more manufacturers are looking to benefit from the ever-expanding array of automation tools and products available. At the heart of every system are network and communication protocols that connect sensors and devices to controllers; sites often combine industrial ethernet with fieldbus systems such as CANopen, AS-Interface, Profibus, CC-Link or DeviceNet, so where would a new I/O solution sit? Kieran Bennett, Field Segment Manager for hygienic – Food and Beverage at Burkert, looks at IO-Link and the advantages it offers for industrial process control.

Can your CAD system select the right threaded fasteners?
Challenge Europe often comes across the risks of excessive reliance on the automatic specification selection feature in many CAD systems at the design stage. These systems match physical dimensions but frequently neglect the materials or stock availability. This is also the case where, for example, a standardised component is requested, but in a material not covered by that standard. This focuses on the need to consult a specialist fastener supplier, especially regarding subcontract assemblies, since it may be that they cannot actually comply with the original drawing. In turn this has a major time implication in getting changes made when compliance is impossible.

CNC or PLC – what is best for Cartesian co-ordinate robots?
In order to remain competitive, it is generally accepted that industries should adopt lean manufacturing strategies to improve process efficiency. A key action can be to reduce part count, i.e. the number of components in an assembly or system. This is particularly challenging when it comes to highly accurate Cartesian co-ordinate (linear) motion applications. In these cases, machine builders would often need to use both PLCs and computer numerical controllers (CNCs) in order to fully manage movement within the machine – until now. Barry Weller, Product Manager at Mitsubishi Electric, looks at how to simplify the control architecture of Cartesian co-ordinate robots.
