6.19 3-DIMENSIONAL CIRCULAR INTERPOLATION (G02.4 AND
G03.4)
Specifying an intermediate and end point on an arc enables circular
interpolation in a 3-dimensional space.
An arc in a 3-dimensional space is uniquely defined with its start point
(current position) and a specified intermediate point and end point, as
shown below. Two command blocks are used to define this arc. The
first command block specifies the tool path between the start point and
intermediate point. The second command block specifies the tool path
between the intermediate point and end point.
