Circle with tangential transition: CT

Functionality
With CT and the programmed end point in the current plane G17 through G19, a circle is
generated which is connected tangentially to the previous path segment (circle or straight
line) in this plane.
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.
