6. Interpolation Functions
Detailed description
(1) Designate the stage P for the 1st block of NURBS interpolation.
(2) Designate the same coordinate value for the 1st block control point of NURBS interpolation as
that designated right before NURBS interpolation.
(3) Designate all axes to be used in the subsequent NURBS interpolation blocks for 1st block of
NURBS interpolation
(4) Set the same value for knot K from the 1st block of NURBS interpolation to setting value block
of the stage P.
(5) Command knot K exclusive block of the same number as the setting value of the stage P for
terminating NURBS interpolation. At this time, set the same value for knot K setting.
(Note) If an exclusive knot is commanded after NURBS interpolation immediately, NURBS
interpolation mode is active again.
An exclusive knot that is commanded after NURBS interpolation immediately is the same
meaning as following command.
