In FANUC terminology, what is "interpolation"?

In FANUC terminology, interpolation refers specifically to the method of calculating intermediate points between two coordinates. This process is essential for CNC (Computer Numerical Control) machining, as it allows the machine to move smoothly from one point to another by generating the necessary movement paths. Interpolation is crucial in ensuring the precision necessary for machining operations, as it determines not only the end points of a tool's path but also how the tool travels to those points.

Since CNC machines need to execute complex shapes and contours, interpolation algorithms help in determining how to best move the cutting tool between sets of coordinates while maintaining accuracy and speed. This involves different types of interpolation, such as linear interpolation, circular interpolation, and spline interpolation, each serving a unique purpose in motion control.

The other options do not accurately capture the concept of interpolation within FANUC terminology. Improving software performance, creating backups for CNC programs, and training robotic systems, while important in the broader context of CNC operations and automation, do not pertain to the specific process of calculating and executing paths between coordinates in machining processes.
