Opt, Dist and Angletol optimization possibility
Opt="P" specifies that the dynamic behavior of the following axis for the speed limitation of
the leading axes and, in particular, is recommended when kinematic transformations are
used.
The parameters (Dist and Angletol) limit the error between the following axis and the
tangent of the leading axes precisely.

Insert intermediate block at contour corners
Delete definition of a tangential follow-up.
Example: TANGDEL (FAxis)
Following axis: additional tangential following rotary axis.
Leading axes: path axes, which determine the tangent for the
following axis.
Coupling factor: relationship between the angle change of the
tangent and the following axis.
Parameter optional; default: 1
Identifying letter for coordinate system
"B" = Basic coordinate system; entry is optional; default setting
"W" = Workpiece coordinate system is not available
Optimization:
"S" Standard, Default
"P" automatic adaptation of the characteristic over time of the
tangential axis and the contour
Offset angle of following axis
Smoothing path of following axis, required with Opt "P"
Angle tolerance of following axis, (optional), evaluation only with
Opt= "P"
