Overview of this book

Until recently, Computer Numerical Control (CNC) machines belonged to the realm of heavy industry, but as technology becomes cheaper and smaller, these machines now can be used in home workshops. It’s not easy to get started, though, but thanks to this guide, you’ll be ready to take on a variety of projects in no time. A Tinkerer’s Guide to CNC Basics contains everything you need to get set up at home with computer-controlled machining and fabrication. Sparing you the theory, this project-laden guide helps you learn by doing. Once you’ve got to grips with the principles of CNC and installed the 3018 Pro CNC machine, you’ll gradually move from simple projects such as basic engraving to more complex milling and machining techniques. You’ll even learn how to upgrade your machine to accomplish more sophisticated designs. The plethora of projects in this book will keep you busy and give you the practice you need to get started with your computerized workshop. By the end of the book, your computerized home workshop will be one step closer to realization, and your machining skills will be taken to the next level.

Chapter 11: Building a More Capable CNC Machine

Cutting hardwoods, plywood, and balsa

Wood is the easiest material to mill with desktop machines. The material is relatively plentiful and much of what we do with wood can also be applied to engineered wood such as MDF, pressed/particle board, and manufactured board. I have recycled materials from scrapped IKEA furniture for years and cut it with a CNC machine and laser for all sorts of projects. You can even make some interesting engraved art with the laminated stuff. A lot of what I do extensively recycles materials like this to minimize waste (I recently built a full flight-simulator panel using engineered wood repurposed from an old foosball table).

Softer woods, such as balsa, can’t be cut effectively with a high-speed end mill if they’re too thin. The fibers will quickly shred and destroy the workpiece. This is also true for any wood, but really soft wood is most susceptible. If I am cutting thin bulkheads for a model airplane it is far more efficient to use...
