Which of the following commands is used to change the tool in FANUC control systems?

The command used to change the tool in FANUC control systems is the TOOL command. This command is designed to define or modify the active tool being used by the CNC (Computer Numerical Control) machine. In FANUC systems, utilizing the TOOL command effectively allows operators to switch the tools as needed for different machining operations, which is essential for multi-tool setups.

Understanding this command's role is crucial for ensuring that the correct tool is engaged for a specific task, as each tool is typically assigned a designated number or code within the system. This facilitates the seamless transition from one tool to another during the machining process, optimizing workflow and enhancing precision in operations.

Other commands such as CHANGE, SELECT, and SET do not have the specific function of changing tools within the FANUC control system. While they may serve other purposes like changing settings or selecting options, they do not directly address tool management, which is vital for successful CNC machining.
