A new international standard has been published for the design, manufacture, and testing of electro-sensitive protective equipment for safeguarding machinery. The guideline, issued by the IEC, covers opto-electronic devices, such as light curtains and light-beam devices. Many machines have such devices to sense whether a person is hazardously close. The new standard covers only the functioning of the electro-sensitive protective equipment and how it interfaces with the machine. It does not specify the dimensions or configurations of the detection zone and how it relates to hazardous parts for any particular application. Nor does the standard specify what constitutes a hazardous state for any machine.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
