Spline Motion Type
When performing operations such as welding, cutting, and applying primer; using the spline
motion type makes teaching for workpieces with irregular shapes easier. The path of motion is
a parabola passing through three points. When spline motion is used for teaching a robot axis,
the move instruction is MOVS.
Single Free Curve
When a single free curve movement is required, teach the spline motion for three points, P1 to
P3, as shown in the figure below. If joint or linear motion is taught at point P0, the point before
starting the spline motion, the manipulator moves from P0 to P1 in a straight line.
Continuous Free Curves
The manipulator moves through a path created by combining parabolic curves. This differs
from the circular motion type in that steps with identical points are not required at the junction
between two free curves.
When the parabolas overlap, a composite motion path is created.
