Digital Fabrication for Designers: CNC Cut Wood Joinery This topic discusses the design and cutting of wood joinery using CNC routers. In learning about CNC cut joinery it is well worth looking at the types of wood joints that have been cut with traditional tools (saws, chisels, tablesaws, bandsaws, etc.) for many years. This will help develop an understanding of the use conditions of the joints, and to visualize some solutions that have been created to deal with them. Later we'll see that the constraints of using CNC routers make clear that joints which are specifically designed or adapted to the process are the most suitable. Terminology Here are some basic terms used in all the forms of joinery discussed below: Pocket: A recess cut into a piece, usually to accommodate a mating part from the other member in the joint. Groove: A slot (U shaped flat bottom cut) or channel made with the grain. Dado: A slot made across the grain. Rabbet: A slot cut parallel to, and along the edge of, a board.

Media Quick Links Useful Searches Recent Posts Open CNC Furniture Open design isn’t just for machines and electronics, With the rise in popularity of CNC routers and laser cutters, there is now an expanding open furniture movement. The result is a fabrication movement where designs are shared globally but fabricated locally and parametric design enables infinite configuration for personal fabrication. Every design featured in this article is available for download. Lean Desk – Original OpenDesk, an open-source project commissioned by Mint Digital. Open Desk Edie Set – designed by brothers Joni and David Steiner, for their niece, Edie, when she was 18 months old. The OpenDesk project provides free downloads of designer furniture files that you can CNC. Lynton Pepper’s Wiki Booth was designed to provide extra privacy in shared workspaces. All designs on Open Desk are downloadable, but their attributes are not easily editable to adjust for different material thicknesses or spacial configurations.

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. The manufacturing process takes 2 hours.

Download all the files for this chair here and open the 3D model with a CAD (computer-aided design) application. Reed Young I built this chair at the Visible Futures Lab of the School of Visual Arts in New York City. (Photograph by Reed Young) If you're working from our files, you'll see I've completed the following software steps for you. All set? Now for the fun part: the assembly. Download This Chair

I wanted to be able to look at them all at once at marvel at their beauty, so I whipped up this poster-format visual reference. It's under CC non-commercial share-alike license.

CNC Joinery part 2: Complex Jigsaw Miter Flat Joint This is part two of our tutorial series entitled "Practical CNC Joinery." In part two of the series we will be discussing how to create complex jigsaw miter flat joints. Material: 3/4" sheet stock MDO (Medium Density Overlay), four inch pieces of wood in a flat arrangement Machine: 3 axis greenBull CNC machine Software: AutoCAD (Design), CAMBAM (Machine tools), Mach3 (Post processor) This is the second part in a tutorial about fashioning joints using a CNC machine. First take into consideration the following: the amount of material will matter due to vibrations and beware of a sawtooth issue. We start out with four inch pieces of wood, just like last time, but in a flat arrangement. However, there are a couple problems with this joint. Now the joint looks like it will be usable and does not go outside of the boundary. Next we used the BO command to put a polygon to make sure there is a nice corner around the edge.
50 Digital Wood Joints | Flexible Stream Wood Joints are fascinating! They embellish old furniture and wood constructions of ancient Japanese temples alike. Everytime we come across them, we are filled with admiration: Admiration for the skill of the master craftsman, as their creator, but also admiration for the balance between function and beauty, which turns the furniture or temple into a work of art. With the onset of industrialisation, the traditional wood joints have been banned more and more to the background. Manufacturing has to be above all efficient, so there is no more room for traditional wood joints. As computer-controlled wood processing machines move into the cabinet-makers' workshops, the way two pieces of wood are joined together in a construction needs to be reconsidered. The result of this research are 50 digital wood joints, divided into frame joints, board joints and carcass joints. We are looking forward for the submission of your modifications and pictures of implementation.
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. 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 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.
CNC Panel Joinery Notebook | Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers 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. Maybe this article can serve as a jumping-off point. In any case, I think it’s time to share my notebook of CNC panel joinery. 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. Laser vs. Biasing Cross (“X”) Joints
