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

Making the First Cut

Now that our CNC machine is operational and provisioned, we can begin to test out its capabilities through some basic cuts. Depending on the material and the nature of our project, we can choose to cut or engrave – or do both. For example, we might want to make an engraved plaque but then have the CNC machine shape it out of our work material. We might also want to machine a component that has grooves, countersunk holes, or markings.

This chapter will show you how to do the following:

  • Secure your workpiece especially if your ultimate objective is to end up with a finished product cut out of the stock material.
  • Select a test pattern to see the various effects. One of the options here is to use a laser to replicate shading effects as might be visible in a photograph. Think of a black and white image and the various shades of gray. You can replicate this using a laser on just about any material.
  • Manipulate configuration settings to achieve...
