Kinematics data expansions
• Possibility of direct access to existing machine axes in order to define the toolholder
• Extension of the kinematics with rotary workpiece and on kinematics with rotary tool and
• Possibility to permit only discrete values in a grid for the rotary axis positions (Hirth tooth
The extensions are compatible with earlier software versions and encompass the kinematic
data blocks from $TC_CARR18 to $TC_CARR23.
Machine with rotary tool
On machines with rotary tool there is no change in the definition of the kinematics compared
to older software versions. The newly introduced vector l

The term "Toolholder with orientation capability" is actually no longer really appropriate for
the new kinematic types, with which the table can also be rotated, either alone or additionally
to the tool. However, it has been kept for reasons of compatibility.
The kinematic chains used to describe the machine with rotary tool (general case) are shown
in the figure below:
