Circle with tangential transition: CT
Functionality
With CT and the programmed end point in the current plane (G18: Z/X plane), a circle is
produced which tangentially connects to the previous path segment (circle or straight line).
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.

Fixed point approach: G75
Functionality
By using G75, a fixed point on the machine, e.g. tool change point, can be approached. The
position is stored permanently in the machine data for all axes. A maximum of four fixed
points can be defined for each axis.
No offset is effective. The velocity of each axis is its rapid traverse.
G75 requires a separate block and acts non-modal. The machine axis identifier must be
programmed!
In the part program block after G75, the previous G command of the "Interpolation type"
group (G0, G1,G2, ...) is active again.

Note
FPn is referencing with axis machine date MD30600 $MA_FIX_POINT_POS[n-1]. If no FP is
programmed, then the first fixed point is selected.
