Circular interpolation with tangential transition (CT)

Function
The Tangential transition function is an expansion of the circle programming.
The circle is defined by
• the start and end point and
• the tangent direction at the start point.
The G code CT produces an arc that lies at a tangent to the contour element programmed
previously.
