Circular Interpolation
Circular interpolation is when two axes work together to cause movement along the outer rim of a circle. The circular interpolation moves using the CIRP and CIRN commands will perform a complete 360° circle using any two axes. When less than 360° of motion is needed, then arc interpolation is used with the ARCP and ARCN commands. The two functions can be combined when more than 360° of motion is needed.
