Description:
When the 3rd axis which is vertical to arc plane moves, G02/G03 is to
be helical interpolation. The choice of helical interpolation is the same as
circular interpolation. Helical interpolation uses G code(G17/G18/G19) to
decide which plane to do circular interpolation.
G17 form: synchronously with arc of X-Y plane.
G18 form: synchronously with arc of Z-X plane.
G19 form: synchronously with arc of Y-Z planeExample:
