8 Programming: Cycles 144
8.2 Point Tables (only TNC 410)
You should create a point table whenever you want to run a cycle,
or several cycles in sequence, on an irregular point pattern.
If you are using drilling cycles, the coordinates of the working plane
in the point table represent the hole centers. If you are using
milling cycles, the coordinates of the working plane in the point
table represent the starting-point coordinates of the respective
cycle (e.g. center-point coordinates of a circular pocket). Coordinates
in the spindle axis correspond to the coordinate of the workpiece
surface.
