The direction of the imaginary tool nose viewed from the tool nose center
is determined by the direction of the tool during cutting, so it must be set

The direction of the imaginary tool nose can be selected from the eight
specifications shown in the Fig.15.2.2 below together with their
corresponding codes.
This Fig15.2.2 illustrates the relation between the tool and the start
