Settings specific to TRANSMIT

Type of transformation
The following paragraph describes how the transformation type is specified.
TRAFO_TYPE_n
The user must specify the transformation type for the transformation data blocks (maximum
n = 10). The value 256 must be set for TRANSMIT or the VALUE 257 for a rotary axis with
supplementary linear axis.
Example for VALUE 256: MD24100 $MC_TRAFO_TYPE_1=256
The setting must be made before TRANSMIT or TRANSMIT(t) is called, where "t" is the
number of the declared TRANSMIT transformation.
The TRANSMIT transformation requires only a rotary axis and a linear axis positioned
perpendicular to the rotary axis. A real Y axis is used with transformation type 257 in order to
compensate for a tool offset, for example.
Transformation type 257
Polar transformation with a rotary axis TRAFO_TYPE_n = 25710.04
Transformation with supplementary linear axis
If the machine has another linear axis which is perpendicular to both the rotary axis and the
first linear axis, transformation type 257 can be used to apply tool offsets with the real Y axis.
It is assumed that the working area of the second linear axis is small and is not to be used
for the retraction of the part program.
The existing settings for MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB_n apply.
Axis image
The following paragraph describes how the transformation axis image is specified.
