Chapter 1: Understanding CNC Machining

1.1 What is CNC Machining?

CNC machining is a manufacturing process that utilizes computer-controlled machines to perform precise milling, turning, drilling, and other machining operations. Unlike traditional machining, which involves manual operation, CNC machining relies on pre-programmed software to dictate the movements of machinery, allowing for a higher degree of accuracy and repeatability.

1.2 Core Components of CNC Machining

CNC Machine: The primary equipment used, which can include mills, lathes, routers, and laser cutters.

Computer Software: Programs such as CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) that help design and generate machining instructions.

Tooling: Specialized cutting tools and fixtures for specific applications.
