Many of today’s digital fabrication technologies are not all that new, just a variation on a theme. For instance, electric motors and methods of controlling their speed have been around for more than a century, but new technologies in motor types and their control are critical to the operation of CNC equipment.



Staying sharp, but rooted in traditional ways

cutting2Oftentimes, when a woodworker hears about a CNC machine, the conversation revolves around a three-axis router for cutting sheet goods, along with debates about the machine’s costs and benefits. Yet very few give thought to how CNC machines other than three-axis routers bring benefits to their shops.



Easy digital shortcuts are worth the time and money

Many woodworkers are intimidated by digital fabrication, scared away by the prices of hardware and software components and the amount of training required. But there are some inexpensive shortcuts.



Post-processor software provides the final kick

When starting in the digital fabrication world, there are many pieces — both hardware and software — that are obvious. Eventually you’ll discover other sophisticated technology that affects performance.



The intricate science behind CNC tooling

john_englishJohn Parsons was born in Detroit in 1913. Thanks to Henry Ford and others like him, that was a good place to grow up if you wanted to be an inventor. After two world wars and an economic depression, Parsons was working at Wright-Patterson Air Force Base near Dayton, Ohio during the late 1940s. He and his assistant, Frank Stulen, were designing propeller blades for helicopters when Parsons conceived the notion of using nascent computer technology to control the path of a cutter.
