Fine offset parameters
$TC_CARR41 to $TC_CARR65 include fine offset parameters that can be added to the
values in the basis parameters. The fine offset value assigned to a basic parameter is
obtained when the value 40 is added to the parameter number.
Example
The toolholder used in the following example can be fully described by a rotation around the
Y axis.
