Example of a 3-axis and 4-axis transformation

3.13.2.1

Example of a 3-axis transformation

Example: For the schematically represented machine (see "Figure 3-1 Schematic diagram of
3-axis transformation (Page 139)"), the 3-axis transformation can be projected as follows:
Program code
$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
3.13.2.2

Example of a 4-axis transformation

Example: For the schematically represented machine (see "Figure 3-2 Schematic diagram of
a 4-axis transformation with moveable workpiece (Page 140)"), however, with an additional
axis (Y), the 4-axis transformation can be configured as follows:
Program code
$MC_TRAFO_TYPE_n = 18
$MC_TRAFO_GEOAX_ASSIGN_TAB_n[0] = 1
$MC_TRAFO_GEOAX_ASSIGN_TAB_n[1] = 2
$MC_TRAFO_GEOAX_ASSIGN_TAB_n[2] = 3
$MC_TRAFO_AXES_IN_n[0] = 1
$MC_TRAFO_AXES_IN_n[1] = 2
$MC_TRAFO_AXES_IN_n[2] = 3
$MC_TRAFO_AXES_IN_n[4] = 0
3.13.3

Example of a universal milling head

General
The following two subsections show the main steps which need to be taken in order to activate
a transformation for the universal milling head.
