Biography/History:

Najia Samer: Samer has been extremely interested in things that fly since he was six years old. An avid pilot, flight instructor, rocketeer and plastic modeler, he has been building things that fly or look like they might for as long as he can remember, including a full scale aircraft in the garage. Samer has a background in Mechanical Engineering and is a CNC and Laser hobbyist, but currently is working in IT specifically software development. Samer resides in Alexandria, VA with his wife and two children and participates in his local maker space by teaching metal shaping techniques, rocketry and homebuilt aircraft construction.

Summary:

Get started with CNC machining using this hands-on guide that tells you exactly what you need to know without overloading you with useless theory Key Features Get started with the basics of CNC machining and set up your own computerized workshop Explore loads of do-it-yourself projects to practice what you've learned Take advantage of the potential of home machining thanks to the power of CNC Book Description 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. What you will learn Configure, calibrate, provision, and test your CNC machine Add a laser engraver to your machine for finer precision cutting Use the machine to fabricate new components for itself Explore the design impacts of carving on a rotary axis Adapt other machines for CNC Engrave opaque and semi-opaque materials Cool your machine with an air assist system Design and develop a customized laser mount Who this book is for This book is for tinkerers, hobbyists, and craft aficionados comfortable using hand tools, aspiring to accelerate or develop more complex and challenging projects. Before starting this book, you should be comfortable around basic shop tools, as well as have a basic understanding of computers. While the book will speak to the specifics around the electronics of CNC machines, the terms used, such as motherboard, USB, positive/negative terminal, and power supply should not be too daunting to understand.
