TRAORI 5-axis transformation
3.5.1 Kinematics and tool orientation
If you were to compare different kinematics with one another, this would very quickly reveal that
different machine movements are required for the purpose of machining the same surface and
that different NC programs therefore also need to be created. In this example, a lateral cylinder
surface is to be machined.
Motion sequence for different kinematics
Motion sequence for head/head kinematics
For a rotation, a semi-circle must be defined in
X/Y and the tool rotated around Z at the same
time so that the tool remains perpendicular to
the surface at all times.
As a rule, if a machine is being used in conjunction with SINUMERIK, you need not con-
cern yourself with the machine kinematics during programming. All you need to concen-
trate on is the relative motion between the tool and workpiece. The control system will
take care of everything else.

Motion sequence for table/table
To achieve a rotation, the table swivels 90°
around the A axis. In each case, the C axis
rotates from +90° to -90° and the tool moves in
the Y axis.
