A CNC wood router is a tool that cuts out objects from wood. Objects are designed on the computer with CAD/CAM programs, then sent to the router for cutting, making CNC routers great for hobbies, engineering prototyping, art, robotic education, and other applications.
CNC routers are typically very expensive, costing thousands of dollars in some cases, but thereʼs recently been a movement in DIY CNC. One of the sites embracing this movement is http://hobbyrouterplans.com, which sells DIY CNC wood router plans. Designed for the hobbyist, these plans are perfect for most weekend warriors. Nearly 2,000 have been purchased over the last 10 years to build everything from model airplane parts, to toys, to milling PCBs.
The finished machine has a 9”x24” cut area – big enough for most hobby projects – and has open ends to allow for unlimited stock length, a neat little feature. Itʼs constructed from birch plywood and other easy-to-find materials such as a Dremel type rotary tool and inexpensive stepper motors and controllers.
One of my favorite features is the vacuum part hold-down feature. This ensures the pieces stay in place, but without compromising the cutting surface or harming the part with straps or clips. Also, it keeps the cut pieces in place to ensure they donʼt get snagged and damaged by the drill. In addition to standard cutting, the router can easily be converted to milling of PCB with the
included plans and instructions. The PCB cut area is 9”x9”, adding a new dimension to the router for rapid prototyping and circuitry-related hobbies. The plans are very comprehensive and include detailed construction notes, bill of materials and suppliers list, CAD drawings, 16 color photographs, and PCB milling conversion instructions.
