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.
See the following illustration for circle with end point and intermediate point specification:

11.4.3
Circle with tangential transition: CT
Functionality
With CT and the programmed end point in the current plane (G18: Z/X plane), a circle is produced which tangentially
connects to the previous path segment (circle or straight line).
This defines the radius and center point of the circle from the geometric relationships of the previous path section and the
programmed circle end point.
See the following illustration for circle with tangential transition to the previous path section:
