Designers of composite parts can choose from a huge variety of fiber reinforcements and resin systems. Knowledge of material properties is a prerequisite to satisfactory product design, but cost is a ...

There are thousands of designers who design injection molded parts but there is an elite group within this large community who can actually design parts for injection molders. Injection molded product ...

Editor's Note: An updated version of this information can be found here. What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, ...

When it comes to creating miniature parts, innovative cutting and machining processes continually make more intricate features and precise geometries possible. Although advanced machining can create ...

Thanks to a team of mechanical engineers at the University of Wisconsin-Madison, design engineers now have Web access to 3D design-optimization software that will help them more quickly create parts ...

Last week, we took a cursory look at the collaboration between General Motors and Autodesk, resulting in refined part designs made real by 3D printing. The system promises significant benefits to ...

OpenSCAD has a lot of fans around these parts — if you’re unaware, it’s essentially a code-based way of designing 3D models. Instead of drawing them up in a CAD program, one writes a script that ...

In Part 1, I discussed the background behind lock-in amplifiers. Here, I’ll cover analog and digital lock-in amplifiers, software-defined radio, de-embedding, and the hardware and software ...
