When early manufacturing giants realized that their mass production techniques would not be effective if they wished to maintain their competitive edge, they started to research new manufacturing methods. One of the most remarkable outcomes of these efforts was rapid prototyping. In the past, production had always been a way to convert or shape a …
Some of the most significant challenges facing the automotive industry include raw material cost, light-weighting and achieving mass production. These are direct consequences of environmental requirements becoming more rigorous as concern about carbon emissions grows. Moreover, the use of carbon fiber is an important part of the answer to these problems but brings on its own set of issues that need to …
Astronomical telescopes enable astronomers to see into deep space and unravel the mysteries of the universe. Freeform mirrors surfaces offer substantial benefits by providing additional degrees of freedom that make it possible to improve the optical performances of the instrument. Freeform optical mirrors surfaces must be construct with nano-scale accuracy to produce clear images. Currently, …
The LEGO Company has built its brand on delivering quality products and experiences that boost creativity in children around the world. Every hour, more than 1.4 million LEGO parts are produced, making up the 100 million LEGO sets produced annually. For LEGO, each part and change – even small changes in material usage – has …
When discussing the benefits of simulation, time and money savings are usually the biggest headlines, as they should be. But these also promote better design. To avoid multiple iterations and meet design specifications, engineers tend to design conservatively, as was the case at TürkTraktör (Turkey’s largest producer of tractors). The problem with this approach is …
Cars, even when driven by careful drivers, will almost definitely experience misuse, peak load or strength events, such as driving over a curb or skidding against a curb a few times during their lifetimes. These durability load cases play can significantly influence the design for several components. At Volvo, the “driving over a curb” and …
