Further information
Resolved kinematics
For machines with resolved kinematics (both the tool as well as the workpiece can be
rotated), the system variables have been expanded by the entries $TC_CARR18[m] up to
$TC_CARR23[m] and are described as follows:
The rotatable tool table consisting of:
● The vectorial clearance of the second rotary axis V
508
that can be rotated I of the third rotary axis.
