What does it mean if a FANUC machine is said to have high "repeatability"?

High "repeatability" in the context of FANUC machines refers to the machine's ability to execute the same task consistently with extreme accuracy over multiple cycles or operations. This characteristic is crucial for ensuring that the output of the machine remains within specified tolerances, even after numerous repetitions of the same task.

In manufacturing and automation, repeatability is essential for producing high-quality parts that meet tight specifications. Machines that exhibit high repeatability can perform processes like milling, drilling, or cutting with minimal variation, thereby increasing efficiency and reducing waste.

The other options, while they may describe important aspects of machine performance, do not accurately represent the concept of repeatability. For instance, operating at high speeds pertains more to the productivity of the machine rather than its ability to produce consistent results. Operating longer without breaks and requiring less human supervision relate to aspects of machine endurance and automation efficiency, but again do not define repeatability.
