1.13.2.1

Example of a 3-axis transformation

Example: For the machine schematically presented in Figure "Schematic Presentation of a 3-
axis Transformation" (see Chapter "3- and 4-axis Transformation", Short Description), the 3-
axis transformation can be projected in the following way:
$MC_TRAFO_TYPE_n = 18
$MC_TRAFO_GEOAX_ASSIGN_TAB_n[0] = 1
$MC_TRAFO_GEOAX_ASSIGN_TAB_n[1] = 0
$MC_TRAFO_GEOAX_ASSIGN_TAB_n[2] = 3
$MC_TRAFO_AXES_IN_n[0] = 1
$MC_TRAFO_AXES_IN_n[1] = 0
$MC_TRAFO_AXES_IN_n[2] = 3
$MC_TRAFO_AXES_IN_n[4] = 0

; x-axis is channel axis 1
; y-axis is not used
; z-axis is channel axis 3
; there is no second rotary axis
