Activation Via Parts/Program/Softkey; Orientation Compression; 5-Axis Transformation; Kinematic Transformation - Siemens SINUMERIK 840D sl Function Manual

If the tool orientation changes, the tool length offsets that apply are rotated so that the pivot
point for the orientation movement always refers to the corrected tool tip.

Activation via parts/program/softkey

The machine data relevant to the kinematic transformation has thus far been activated mostly
through POWER ON.
Transformations MDs can also be activated via the part program / softkey and it is not
necessary to boot the control system.

Orientation compression

During the execution of NC programs containing blocks with relatively short traverse paths,
the interpolator clock cycle can lead to a reduction in tool path velocity and a corresponding
increase in machining time.
COMPON, COMPCURV, COMPCAD
You can run NC programs with short traverse paths without reducing the tool path velocity by
activating "compressors" COMPON, COMPCURV or COMPCAD. The compressor also
smoothes the programmed movements and consequently tool path velocity.
Programming of direction vectors
Programming of tool orientation that is independent of the kinematics, can be achieved through
programming of direction vectors. NC programs with such direction vectors can be executed
with compressors COMPON, COMPCURV and COMPCAD.

Kinematic transformation

Task of orientation transformation
The task of orientation transformation is to compensate movements of the tool nose, which
result from changes in orientation, by means of appropriate compensating movements of the
geometry axes. The orientation movement is therefore decoupled from the movement on the
workpiece contour. Various machine kinematics each require their own orientation
transformation.
