Additional notes
The number of the respective toolholder to be
programmed is specified with "m".
The start/endpoints of the distance vectors on the axes
can be freely selected. The rotation angles around the
two axes are defined in the initial state of the toolholder
with 0°. In this way, the kinematic description of a
toolholder can be programmed unambiguously for any
number of possibilities.
If the two rotary axes intersect, it is not necessary to
specify the distance between the two axes.
Toolholders with only one or no rotary axis at all can
be described by setting the direction vectors of one
or both rotary axes to zero. With a toolholder without
rotary axis the distance vectors act as additional tool
offsets whose components cannot be affected by a
change of machining plane (G17 to G19).
