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.

This is when I discovered the table’s legs were made of this exquisite and still good hardwood. Naturally, they encountered my miter saw and now, slices of the table’s legs are workpieces for my CNC machine and laser cutter.

The denser the material you cut, the more your machine needs to be rigid and your axes precise. As you gain more experience with various materials, you will find the feed rate for the denser materials, such as hardwood, will have to be slower and require multiple passes. As before, we are going to use a downcut bit because we want...
