- Circular interpolation controls two or
more axes so that the start point and
the end point (target position) are
connected with circular arc.
- As there are innumerable number of
arc locus connecting two points, an
auxiliary point, the arc radius, the
X axis
center or the direction should be
specified in addition to the start point
and the end point to determine the
circular arc.
