Transformations

7.8 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.

TRANSMIT or TRANSMIT(n)

The rotary axis cannot be programmed because it is occupied by a geometry axis and

cannot thus be programmed directly as a channel axis.

An active TRANSMIT transformation is likewise deactivated if one of the other

transformations is activated in the relevant channel (e.g., TRACYL, TRAANG, TRAORI).

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.
