(1) When the normal direction changes between blocks N1 and N2,
cutting point compensation is applied between blocks N1 and N2.
As shown in Fig.4.10 (i), cutting point compensation is applied
according to (1) of cutting point compensation, described above,
together with the movement resulting from normal direction control
between blocks N1 and N2.

and N2
(2) When the normal direction is changed by gradual curve normal
direction control together with the movement of a specified block,
cutting point compensation is performed together with the
movement of the specified block. When a rotation of θ1 is made on
the normal direction control axis together with the movements of
blocks N1 and N2 as shown in Fig.4.10 (j), cutting point
compensation based on vector V1 movement is also performed
together with the movement of block N2.
