Transformations
6.8 Kinematic transformation
TRANSMIT transformation types
The TRANSMIT machining operations have two parameterizable forms:
• TRANSMIT in the standard case with (TRAFO_TYPE_n = 256)
• TRANSMIT with additional Y linear axis (TRAFO_TYPE_n = 257)
The extended transformation type 257 can be used, for example, to compensate clamping
compensations of a tool with real Y axis.
Syntax
TRANSMIT or TRANSMIT(n)
TRAFOOF
Rotary axis
The rotary axis cannot be programmed because it is occupied by a geometry axis and cannot
thus be programmed directly as a channel axis.
Significance

TRANSMIT(n):
TRAFOOF:
OFFN:
Note
An active TRANSMIT transformation is likewise deactivated if one of the other
transformations is activated in the relevant channel (e.g., TRACYL, TRAANG, TRAORI).
372
Activates the first declared TRANSMIT function. This function is also
designated as polar transformation.
Activates the nth declared TRANSMIT function; n can be up to 2
(TRANSMIT(1) is the same as TRANSMIT).
Deactivates an active transformation.
Offset contour normal: Distance of the face machining from the
programmed reference contour.
