NDB Positioning under normal direction control is carried out:
0 : According to the conventional specification.
1 : By handling the C–axis angle immediately before the beginning of
the normal direction control mode, as an offset value.
With the tool to be used in the normal direction control mode mounted on
a magazine, this parameter is used if the C0 command cannot set the tool
in the +X direction (C0_) defined for normal direction control. If the C0
command sets the tool in the +Y direction (displacement of +90_), for
instance, the direction can be set as C0_ of normal direction control by
doing the following: Set this parameter to 1, and specify the displacement
as C90. before the system enters the G41.1 (G42.1) mode.
NDC Positioning under normal direction control is carried out:
0 : According to the conventional specification.
1 : By handling the C–axis angle immediately before the beginning of
the normal direction control mode, as the direction normal to the next
traveling direction.
This parameter is used to carry out positioning for setting the C–axis in
the normal direction before the system enters the normal direction control
mode. In the normal direction control mode, the positioned C–axis angle
is held in the direction normal to the first traveling direction in the normal
direction control mode.
