
If G19 is used, and the postion of an x-axis does not change, helical interpolation will be
equivalent to circular interpolation.

 Principles of writing an instruction: (1) Users have to specify a target position, and an arc
center. They do not have to specify the speed of interpolation. (2) If there is no vector from the
present position of an axis to its target position, users do not need to specify the target position
of the axis. The circular/helical instrctions listed below are available.

 The path of circular interpolation can not be a 360° arc. The path of helical interpolation which
is viewed from the top can not be a full circle.

Example 1
Absolute coordinates are set, and G02 is used. The arc start point set is (5000, 5000), the arc
end point set is (10000, 10000), and L is 5000. The angle subtended by the arc is less than
180°, and therefore the value of R is a positive value. The axes move at a speed of 1,000 per
second.
