Explanation
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: 0
y component of the tool base dimension: 0
z component of the tool base dimension: 250
Note
The required data cannot be determined unequivocally from the geometry of the toolholder,
i.e., the user is free to a certain extent to decide the data to be stored. Thus, for the example,
it is possible to specify only one z component for the tool base dimension up to the second
axis. In this case, l
2
would no longer be zero, but would contain the components of the
distance between this point on the second axis and a further point on the first axis. The point
on the first axis can also be selected freely. Depending on the point selected, l
1
must be
selected such that the reference point (which can also be selected freely) is reached.
In general: vector components that are not changed by rotation of an axis can be distributed
over any vectors "before" and "after" rotation.
