10.6.7 Circular interpolation with tangential transition (CT, X... Y... Z...)
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.
