4.2 Example of a 3-axis and 4-axis transformation
4.2 Example of a 3-axis and 4-axis transformation
4.2.1 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
4.2.2 Example of a 4-axis transformation
Example: For the machine schematically presented in Figure "Schematic 4-axis
Transformation with movable Workpiece" (see Chapter "3- and 4-axis Transformation", Short
Description), the 4-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] = 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
