The machine control unit (MCU) primarily functions as the brain of the CNC machine, responsible for interpreting and managing the operational commands. It reads the coded instructions provided by the operator or the programming software, which is typically written in G-code or another CNC programming language. Once the MCU decodes these instructions, it translates them into precise movements and actions for the machine's motors and tools, allowing for the correct execution of tasks such as cutting, milling, or drilling.

This capability of the MCU to interpret detailed instructions is what enables the CNC machine to perform complex operations with high accuracy. The ability to decode these commands is essential for ensuring that the machine adheres to the specified dimensions and specifications of the job being performed. This makes the MCU a critical component in the overall functioning and effectiveness of CNC technology.
