Siemens SINUMERIK 840D sl Function Manual page 109

Suitable assumptions were made for the following values in the data block:
● The two rotary axes intersect at one point.
All components of l
● The first rotary axis lies in the x/z plane, the second rotary axis is parallel to the x axis.
These conditions define the directions of v
they are not equal to zero).
● The reference point of the toolholder lies 200 mm in the negative x direction viewed from the
intersection of the two rotary axes.
This condition defines l
Specify associated data block values
The following associated data block values are specified for the toolholder shown on a machine
with rotary toolholder:

Angle of rotation α1 (in degrees)
Angle of rotation α2 (in degrees)
x component of offset vector l
y component of offset vector l
z component of offset vector l
Explanations
The toolholder kinematic chosen in the example is such that the two rotary axes form an angle
of 45 degrees, which means that the orientation cannot take just any value. In concrete terms,
this example does not permit the display of orientations with negative X components.
x component of the tool base dimension:
y component of the tool base dimension:
z component of the tool base dimension:
