3.3.4 NURBS Interpolation
M720VW
M system ―
L system ―
This function realizes NURBS curve machining by commanding NURBS curve parameters (number of
stages, weight, knot, control point). The path does not need to be replaced with fine segments.
This function operates only in the high-speed high-accuracy control 2 mode, so the high-speed high-
accuracy control 2 option is required.
During NURBS interpolation, interpolation takes place at the commanded speed. However, if the curvature is
large, the speed is clamped so that the machine's tolerable acceleration rate is not exceeded.
NURBS interpolation cannot be used during graphic check (continuous/step check).
Linear interpolation that connects the control points is used during graphic check.
