History and Definition of CNC 202

History and Definition of CNC provides a fundamental overview of the development of machine control, from numerical control (NC) to computer numerical control (CNC). NC machines emerged in Industry 2.0 thanks to the invention of the ballscrew and advancements in servomotors and digital tape. Technological developments in Industry 3.0 allowed machines to directly interface with computers, resulting in the first CNC machines. Continuing advancements in digital automation and data exchange are creating new applications for CNC in Industry 4.0. CNC machines are crucial to modern manufacturing and their importance is growing as technology advances. After taking this class, users will be familiar with the origins and defining characteristics of CNC systems. This knowledge will prepare users to learn more about, and ultimately work with, CNC machines.
