How does direct numerical control coordinate several CNC machine tools?

Direct numerical control (DNC) coordinates multiple CNC machine tools by connecting them to a large central computer. Instead of each machine operating independently, this central system serves as the primary hub that stores and processes the operational procedures required for machining.1

By distributing these instructions from a single source, DNC allows for the centralized management of manufacturing tasks across several machines. This setup is a key component of computer-integrated manufacturing, facilitating more efficient control and oversight of the production process.12
