Review: PD 5304:2005 'Guidance on safe use of machinery'
Procter Machinery Guarding takes a close look at PD 5304:2005, 'Guidance on safe use of machinery' and compares it with the version dating from 2000.
The implications of IEC 62061 becoming EN 62061
Although it is all but identical to IEC 62061, BS EN 62061 (Safety of machinery, Functional safety of safety-related electrical, electronic and programmable electronic control systems) is now harmonised to the Machinery Directive, which makes a subtle but important difference. This article explains the implications for machine builders and those modifying machinery, and looks in detail at what the standard contains.
Rapid prototyping, rapid 3D printing and rapid manufacturing
The phrase 'rapid prototyping' means different things to different people. But the concept is now sufficiently established for its supporting vocabulary to be moving from confusing jargon to fixed and well understood definitions. Here Martin Stevens, MD of Unimatic, gives an overview of the techniques and reviews its benefits.
