The What and Why of CNC
Computer numerical control (CNC) is a software-based method of moving tools and machinery. This method has traditionally been under the purview of factories and manufacturing facilities and well beyond the reach of a garage tinkerer.

Our objective in this chapter is to provide a basic understanding of CNC from a hobbyist’s/tinkerer’s perspective as we prepare to take a deep dive into obtaining, operating, and customizing our own machine.
In this chapter, we will cover the following topics:
- Branches of CNC machining
- Differing approaches ...
