This volume explains how computer numerical control milling or CNC milling complements the other processes completed in a Fab Lab. It explains where the CNC milling machine operator fits as a maker. This book includes a robust further information section that fulfills Common Core Standards by offering a means through which readers may draw on information from multiple print or digital sources, demonstrating the ability to locate an answer to a question quickly or to solve a problem efficiently. The projects are ranked by difficulty, allowing readers to build confidence as they go along, or jump ahead if they're advanced of the lower-levels. Real-life examples of how milling machines solve problems are included, along with many photographs of children enjoying Fab Lab activities.
