The 2½ D path control makes it possible to carry out tool movements on several planes by switching the interpolation
in each case on one of the three main planes. All three axes are controllable in 2½ D path control,
however in every plane only two axes simultaneously. The third axes is the so-called infeed axis.
Depending on the selected machining plane different
axis can be controlled simultaneously so that it is
possible to travel in the following directions:
