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.

Building a More Capable CNC Machine

While we have focused our attention on the 3018 machine for most of this book so far, at some point, you will outgrow it. Maybe you need a bigger work area, improved metal machining capabilities, or greater accuracy. The 3018 is a very good all-purpose design, but by now, you will have seen its limitations, and if you have bigger projects in mind, the 3018 definitely will only be part of your overall toolchain.

When I first started with CNC, I built an airplane that required the fabrication of 52 wing ribs. Those were cut from sheet aluminum, and I had to cut the outlines and various-sized holes by hand. I hit upon the idea of cutting the ribs (and some other parts) with a CNC machine, and from there, I never looked back. If you are in the same boat, I am sure you are wondering, what next? So, in this chapter, let’s discuss what you could do to machine bigger things. We have a couple of avenues:

  • Improve and enlarge the 3018
  • ...
