Assignment of names to machine axes
With the cd of the machine axes as a reference, a machine axis name is transferred to the
control system:
MD10000 $MN_AXCONF_MACHAX_NAME_TAB[0]="CM"
MD10000 $MN_AXCONF_MACHAX_NAME_TAB[1]="XM"
MD10000 $MN_AXCONF_MACHAX_NAME_TAB[2]="YM"
MD10000 $MN_AXCONF_MACHAX_NAME_TAB[3]="ZM"

Settings specific to TRACYL

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). For TRACYL a VALUE of 512 must be set for axis configuration 1 and a value of
513 for axis configuration 2 or 514 for no groove side offset with supplementary linear axis.
Transformation type 514 can also be activated with groove side offset by means of an
additional parameter. See the chapter "Activation".
Example for VALUE 512: MD24100 $MC_TRAFO_TYPE_1=512
The setting must be made before TRACYL(d,t) is called – "t" is the number of the declared
TRACYL transformation.
The TRACYL 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 514 in order to
compensate for a tool offset, for instance.
Transformation type 514 without groove side offset
Cylinder surface curve transformation TRAFO_TYPE_n = 514
If the machine has another linear axis which is perpendicular to both the rotary axis and the
first linear axis, transformation type 514 can be used to apply tool offsets with the real Y axis.
In this case, it is assumed that the user memory of the second linear axis is small and will
not be used to execute the part program.
The existing settings for MD10000 $MC_TRAFO_GEOAX_ASSIGN_TAB_n apply.
