M1: Kinematic transformation
7.2 TRACYL cylinder surface transformation (option)
Transformation geometry axes
For the transformation data set <n>, three (or 4) channel axis numbers must be specified for
TRACYL:
● MD24110 $MC_TRAFO_AXES_IN_1[0]=channel axis number of the axis radial to the rotary
axis.
● MD24110 $MC_TRAFO_AXES_IN_1[1]=channel axis number of the rotary axis.
● MD24110 $MC_TRAFO_AXES_IN_1[2]=channel axis number of the axis parallel to the
rotary axis.
● MD24110 $MC_TRAFO_AXES_IN_1[3]=channel axis number of the supplementary axis
parallel to the cylinder surface and perpendicular to the rotary axis (provided two axis
configurations are present).
The axis numbers must refer to the channel axis sequences defined by the following machine
data:
MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB_<n>
Grooves without groove wall offset
For transformation type 514 the following indices apply to MD24110
$MC_TRAFO_AXES_IN_<n>[ ].
Meaning of indices in relation to base coordinate system (BCS):
● [0]: Cartesian axis radial to rotary axis (if configured)
● [1]: Axis in generated cylinder surface perpendicular to rotary axis
● [2]: Cartesian axis parallel to rotary axis
● [3]: Linear axis parallel to index 2 in initial position of machine
Meaning of indices in relation to machine coordinate system (MCS):
● [0]: Linear axis radial to rotary axis (if configured)
● [1]: Rotary axis
● [2]: Linear axis, parallel to rotary axis
● [3]: Linear axis, perpendicular to the axes of indices [0] and [1]
