15. COMPENSATION FUNCTION
Specify the maximum distance for which machining is performed with
the same normal direction as that of the preceding block.
D Linear movement
When distance N2, shown below, is smaller than the set value,
machining for block N2 is performed using the same direction as that
for block N1.
When the diameter of block N2, shown below, is smaller than the set
value, machining for block N2 is performed using the same normal
direction as that for block N1. The orientation of the axis to which
normal–direction control is applied, relative to the normal direction of
block N2, does not change as machining proceeds along the arc.
1 Do not specify any command to the C axis during normal
direction control. Any command specified at this time is
2 Before processing starts, it is necessary to correlate the
workpiece coordinate of the C axis with the actual position
of the C axis on the machine using the coordinate system
setting (G92) or the like.
3 The helical cutting option is required to use this function.
Helical cutting cannot be specified in the normal direction
4 Normal direction control cannot be performed by the G53
5 The C–axis must be a rotation axis.
D Movement for which arc
insertion is ignored
