Which term describes a machine that integrates multiple machining operations with automatic tool changes controlled by NC?

CNC Machining Center

A CNC machining center is a machine that can perform multiple machining operations in one setup and switch tools automatically under program control. It combines functions like milling, drilling, tapping, and boring, all managed by a numerical control system that coordinates tool changes from a tool magazine. This means you write a single program, and the machine moves the spindle, selects the right tool, and executes each operation in sequence without manual intervention. The result is the ability to produce complex parts quickly, with high repeatability and minimal handling.

This is different from a milling machine, which typically performs one main operation at a time and may have little or no automatic tool changing. A lathe specializes in turning operations on a rotating workpiece, not multi-operation milling in a single setup. A router is geared toward routing tasks, often in wood or softer materials, and generally lacks the rigid precision and automation of a machining center.
