Transformation With Swiveled Linear Axis - Siemens SINUMERIK 840DE sl Function Manual

Parameter assignment procedure
● Enter the type of transformation according to the previous table as machine data:
$MC_TRAFO_TYPE_n
● Assign channel axes to the geometry axes of the transformation.
● For a 3-axis transformation, set the values for the axis, which is not required:
– $MC_TRAFO_GEOAX_ASSIGN_TAB_n[<geometry axis>] = 0
– $MC_TRAFO_AXES_IN_n[<geometry axis>] = 0
● For a 4-axis transformation, set the following for the 3 linear axes
– $MC_TRAFO_GEOAX_ASSIGN_TAB_n[<geometry axis>] = ...
– $MC_TRAFO_AXES_IN_n[<geometry axis>] = ...
Complete examples of a 3-axis and 4-axis transformation can be found in "Example for 3- and
4-axis Transformation" section.

Transformation with swiveled linear axis

General information
The "transformation with swiveling linear axis forms" a transformation group of its own. It can
be used when a kinematic as described in the Section "Orientation transformation with a
swiveling linear axis. (Page 140)" is present:
● Three Cartesian linear axes (X, Y, Z) and two orthogonal rotary axes (A, B).
● The rotary axes are parallel to two of the three linear axes.
● The first rotary axis (A) is moved by two Cartesian linear axes. It rotates the third linear axis
(Z) that moves the tool.
● The tool is aligned parallel to the third linear axis (Z).
● The second rotary axis (B) rotates the workpiece.

$MC_TRAFO_AXES_IN_n[ 4 ] = 0; → there is no 2nd rotary axis
$MC_TRAFO_AXES_IN_n[ 4 ] = 0; → there is no 2nd rotary axis
