Circle with tangential transition: CT

Functionality
With CT and the programmed end point in the current plane G17, 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.
