Literary gold mine for CNC millers From 1976 to 1983, Popular Science magazine, along with the American Plywood Association, ran an annual plywood panel project design contest for its readership. Often the winning projects were items of furniture, but that was not a requirement. A potter’s kick wheel and a folding plywood boat are notable exceptions. The rules were simple: Apart from common fasteners, the entire project had to be constructed from one or more panels of plywood, cut to make most efficient use of the material. In 1984, these projects were collected, by original contest editor Alfred W. 1984, of course, was decades prior to the advent of accessible home CNC milling, so all those carefully shaped and slotted parts, at the time, had to be laboriously hand-cut using a jigsaw or similar tool.
CNC Panel Joinery Notebook I’ve been collecting clever ways of slotting flat stock together since I first read Nomadic Furniture back in 1999, well before the advent of the accessible hobby-class CNC tools that today make manufacturing parts like these pretty easy. Now, the world is full of people designing models, project enclosures, sculpture, furniture, and all kinds of other cool stuff to be assembled from parts made on laser cutters and CNC routers. I keep expecting a definitive book or website to emerge that covers the “bag of tricks” in an organized way, but so far, I haven’t found it. In presenting this material, I want to first acknowledge my respect for the world’s established and ancient traditions of joinery. I may abuse some terms, without meaning to, and I am glad to be corrected by those who are in the know about traditional joinery. To simplify things, at first, I’m only considering joints between two panels. Laser vs. The router-cut version, however, doesn’t work. Biasing Cross (“X”) Joints
Lasersaur Manual CNC Joinery Notebook: Update 1 For about ten years, I have been collecting various clever ways of cutting flat stock to design 3D shapes that slot together in space. Back in April, I posted a long, rambling brain-dump from this personal file under the title “CNC Joinery Notebook.” If you pick up a copy of MAKE’s just-released Volume 33, you’ll find a much-polished version of that article on p.59. Since then, a few more patterns have come to my attention, and I thought the publication of MAKE’s new issue was a good opportunity to share them with you. Three Basic Approaches The design vocabulary of CNC panel construction is evolving rapidly. In his article, Bruce mentions a taxonomy of three rudimentary CNC panel-construction techniques that he attributes to Scott Klinker at the Cranbook Academy of Art: the “stack of sections,” the “grid of sections,” and the “graphic profile” technique. Three approaches to designing a router-cut lounge chair. The first two “sectioning” techniques are amenable to algorithmic design.
The future is here at Design Museum / toothpicnations Main and bottom left: The future is here exhibition designed by by Lucienne Roberts+ and drMM; Bottom right: KUKA Robotics' AGILUS robots Work has kept me quite busy lately, but I finally managed to visit "The future is here: a new industrial revolution" exhibition at the Design Museum on its last day at the last hours! We have all witnessed the industrial revolution ( I mean at the 2012 Olympics Opening ceremony directed by Danny Boyle), and this exhibition focused on the possibility of a new one based on the past, current industry trends and technology.

Build Your Own Beautiful Flat-Pack Chair I built this Eames-like chair without touching a single traditional woodworking tool. No, it's not because I'm some kind of Luddite. I just love the immediacy of rendering a chair with 3D modeling software and then cutting out the parts with a CNC machine. Everything snaps together like flat-pack furniture, but without the cheesy fasteners—just mechanically sound through tenons and lap joints.

Download all the files for this chair here and open the 3D model with a CAD (computer-aided design) application.

“The Future Is Here: A New Industrial Revolution” Coming to London’s Design Museum “The Future Is Here: A New Industrial Revolution” Coming to London’s Design Museum This summer, the Design Museum in London will be offering a glimpse into the future of fabrication and manufacturing with The Future Is Here: A New Industrial Revolution, a major new exhibition about the sweeping changes in manufacturing that are transforming our world. The exhibition, which opens July 24, is a collaboration between the Design Museum and the UK’s innovation agency, the Technology Strategy Board.
