What is the role of 'external axes' in a FANUC robotics system?

External axes in a FANUC robotics system play a crucial role in expanding the robot’s workspace and range of motion. By integrating additional axes, such as conveyors, turntables, or other mobile platforms, these external systems allow the robot to reach areas that would be inaccessible with its inherent movements alone. This capability is particularly beneficial in applications where parts may need to be moved while being handled by the robot, facilitating a more efficient workflow.

The use of external axes enhances the versatility of the robotic system, enabling it to perform tasks that require movement beyond the standard reach of the robot’s arm. For instance, combining a robot with an external axis allows for complex paths to be executed, improving productivity and extending the application range in various industries such as packaging, automotive, and material handling.

Thus, the integration of external axes is essential in optimizing the overall functionality of FANUC robotic systems, providing significant benefits in terms of workspace enhancement and the ability to automate processes that would otherwise require more manual intervention.
