What is the purpose of a subprogram command?

The purpose of a subprogram command is to activate a different program. In CNC programming, a subprogram is a separate block of code that is written to perform a specific task, which can then be called upon from the main program. This modular approach allows for code reusability and simplifies the main program by breaking down complex sequences into manageable sections.

When the subprogram command is executed, the CNC machine temporarily halts the main program to execute the instructions within the subprogram. This means that any operations defined in the subprogram can be completed before control returns to the main program, allowing for a more organized and efficient machining process.

Programs that use subprograms can reduce errors and enhance clarity, as repetitive tasks are encapsulated within their own sections of code rather than being repeated multiple times throughout the main program. This also makes it easier to update or modify specific parts of the machining process without having to rewrite the entire main program.
