10.3.4 Circular interpolation via intermediate point: CIP
Functionality
The direction of the circle results here from the position of the intermediate point (between
starting and end points). Specification of intermediate point: I1=... for the X axis, K1=... for
the Z axis.
CIP remains active until canceled by another instruction from this G group (G0, G1, ...).
The configured dimensional data G90 or G91 applies to the end point and the intermediate
point.
