Circular Interpolation With Tangential Transition (Ct, X - Siemens SINUMERIK 828D Programming Manual

9.6.7 Circular interpolation with tangential transition (CT, X... Y... Z...)
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
previously.
Determination of the tangent direction
The tangent direction in the starting point of a CT block is determined from the end tangent
of the programmed contour of the last block with a traversing motion.
There can be any number of blocks without traversing information between this block and
the current block.
