WHEN great designs are turned into products compromises are made. The beautifully sculpted “concept” cars that regularly appear at motor shows never get built, at least not in the form they left the design studio, because they are inevitably too difficult and expensive to engineer for mass production. For decades this has meant products have had to be “designed for manufacture”, which essentially means their components must incorporate features that can be readily shaped by machines in order to be glued, screwed or welded together by people or robots. Now a combination of powerful computer-aided design (CAD) software and new manufacturing methods is changing the game.
Instead of being created with technical drawings and blueprints, most new products are today conceived in CAD systems in a three-dimensional virtual form. As these systems get cleverer some of the design processes themselves are being automated: algorithms suggest the most efficient shapes to save weight, or to provide strength or flexibility according to the loads and stresses placed upon them. Components and even entire products can be tested in their digital form, often using...Continue reading
