Interpolate Axes 233
Full Circles
A complete circle is a special case of a circular arc in which the start and
end point of the arc are the same.
Example 5: Full Circle in Absolute Mode
In Absolute Mode (using either Radius Arc or Intermediate Arc
interpolation), the destination for each axis must be exactly equal to the
command position of the axis at the beginning of the circle. Using the
center point parameters of the previous example (Example 4:
Intermediate Arc Incremental Mode), the Interpolate Axes parameters
shown below use Interpolator 1 to move the axes in the following full
circle as shown in the diagram below.
