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, ...

Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials -- artificially engineered composite materials that derive their properties from patterned ...

While a part’s design may meet all the right functional requirements, that doesn’t mean the design is suited for cost-effective CNC machining. In fact, some part features may be difficult or even ...
