7. Transformations
Keyword/ 1st parameter
function
identifier
TRACYL REAL: Working
diameter
TRANSMIT INT: Number of
transformation
TRAANG REAL: Angle
TRAORI INT: Number of
transformation
TRACON INT: Number of
transformation
TRAFOOF
For each transformation type, there is one command for one transformation per channel. If
there are several transformations of the same transformation type per channel, the
transformation can be selected with the corresponding command and parameters. It is
possible to deselect the transformation by a transformation change or an explicit deselection.

2nd parameter Explanation
INT: Number Cylinder: Peripheral surface transformation
of Several transformations can be set per channel. The transformation
transformation number specifies which transformation is to be activated. If the
second parameter is omitted, the transformation group defined in
the MD is activated.
Transmit: Polar transformation
Several transformations can be set per channel. The transformation
number specifies which transformation is to be activated. If the
parameter is omitted, the transformation group defined in the MD is
activated.
INT: Number Transformation inclined axis:
of Several transformations can be set per channel. The transformation
transformation number specifies which transformation is to be activated. If the
second parameter is omitted, the transformation group defined in
the MD is activated. If no angle programmed:
TRAANG ( ,2) or TRAANG, the last angle applies modally.
Transformation oriented: 4, 5-axis transformation
Several transformations can be set per channel. The transformation
number specifies which transformation is to be activated.
REAL: Further Transformation concentrated: Cascaded transformation; the
parameters, meaning of the parameters depends on the type of cascading.
MD-dependent
Deactivate transformation
2nd parameter Explanation
and others
INT: Spindle Spindle position control ON: Switch to position-controlled spindle
number operation
INT: Spindle Spindle position control OFF: Switch to speed-controlled spindle
number operation
Set master spindle: Declaration of spindle as master spindle for
current channel.
With SETMS( ), the machine-data default applies automatically
without any need for parameterization.
