## Interpolated operations

Interpolated operations involve two or more axes whose movements are interdependent. Interpolation consists of generating data points between given coordinate axis positions and using this data to generate a path in space (linear, arc, circle, or helix) related to the coordinated axes. There are many types of interpolated moves. Linear interpolation is when two or more axes works together to cause movement along a straight line. For linear interpolation, each axis moves in only one direction, and start and stop at the same time. Circular interpolation is when two axes work together to cause movement along the outer rim of a circle. For circular Interpolation, each axis will change direction and speed as required to allow for a circular path of movement. A popular subset of circular interpolation is arc interpolation, when two axes work together to move along the outer rim of a circle for a set number of degrees. Helix or tangential interpolation is when a circular or arc interpolation of the X and Y-axis is combined with linear interpolation of the center point of the circle and the Z-axis. This allows for movement along a helical motion path. These moves can be buffered together to allow for seamless continuous motion.
