Kinematic transformation, toolholder with orientation capability
If a toolholder with orientation capability is taken account of during the tool length calculation, the following
vectors are included in that calculation:
In generic 5-axis transformation, the following machine data are included in the tool length calculation for
transformer types 24 and 56:
Transformation type 56 corresponds to type M for a toolholder with orientation capability.
With this 5-axis transformation in the software versions used up to now, the following vector is equivalent to the
sum of the two vectors l
1
and l
3
for a toolholder with orientation capability type M.
MD24560/24660 $MC_TRAFO5_JOINT_OFFSET_1/2 (vector of kinematic offset of the first/second 5-axis
transformation in the channel)
Only the sum is relevant for the transformation in both cases. The way, in which the two individual components
are composed, is insignificant. When calculating the tool length, however, it is relevant which component is
assigned to the tool and which is assigned to the tool table.
This explains the introduction of new machine data:
MD24558/24658 $MC_TRAFO5_JOINT_OFFSET_PART_1/2 (vector kinematic offset in table).
It is equivalent to the vector l
3
.
