Example 4: MIXED 2
In this example, the reference points of the toolholder and the
tool are identical, as well as the reference points of the table
and the machine.
Thus: I1 = -I2 and
resulting in each case in a closed system.
The advantage of this method is that the position values do not
change in the unswiveled state, regardless of whether the swivel
head or table is selected.
