What is the main purpose of a CNC program?

The main purpose of a CNC program is to provide instructions coded in G-code and M-code for the machine. G-code is the language that tells the CNC machine what actions to perform, such as moving the tool to specific coordinates, controlling the speed, and managing the tool changes necessary for machining operations. M-code, on the other hand, controls auxiliary functions of the machine, such as turning coolant on and off or specifying additional sequences in the machining process. This combination allows the CNC machine to execute complex tasks with precision and automation, thus enhancing manufacturing efficiency and accuracy.

In contrast, outlining budget requirements, managing inventory processes, and creating training materials for operators are distinct activities that pertain more to other aspects of business operations or human resources rather than the core function of controlling a CNC machine's machining processes. These activities might support the overall operation but do not directly relate to the specific instructions necessary for CNC programming and machine operation.
