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

Understanding Material Properties before Making the First Cut

The CNC machines we work with at the desktop level have limitations both in terms of how big a piece of raw material they can process and what the material itself can be made of. Every material has specific properties that require attention when being milled. These properties include hazards from cuttings/dust, viable milling speeds, and heat dissipation, among others.

By the end of this chapter, you will understand the following:

  • The fundamental properties of certain materials to help inform the process of material selection in your projects
  • How to tailor your cutting methods, settings, and preferences to your specific materials, machine and parts you are fabricating

You will also be able to select materials that are viable for your specific project (for example, a generic suggestion to use wood is not enough since you may need material that is light, or durable, or flexible). An important benefit...
