Example
In the example program below, a circle approached by a polygon definition is compressed.
The tool orientation moves on the outside of the taper at the same time. Although the
programmed orientation changes are executed one after the other, but in an unsteady way,
the compressor function generates a smooth motion of the orientation.

COMPCURV
; The movement describes a circle generated
from polygons. The orientation moves on a
taper around the Z axis with an opening
angle of 45 degrees.
