What does "S-curve acceleration" refer to in FANUC motion control?

"S-curve acceleration" in FANUC motion control refers to a method of acceleration characterized by a smooth transition in speed, resulting in a motion profile that resembles an 'S' shape when graphed over time. This method reduces shock to the system and improves response by gradually ramping up the velocity, reaching a constant speed, and then gradually decelerating.

Implementing S-curve acceleration is particularly advantageous in machining applications, as it minimizes abrupt changes that can lead to vibrations and potential damage to the machinery, tools, or the workpiece. The gentle acceleration and deceleration not only enhance the machine's longevity and reliability but also improve precision by ensuring that the machine maintains control throughout its movements.

This approach stands in contrast to more abrupt acceleration methods, which can induce mechanical stress and lead to inaccuracies during operation. Hence, S-curve acceleration is fundamental in optimizing both performance and safety in FANUC controlled systems.
