STAT–PZ : Absolute Z coordinate of the start point for center
drilling or chamfering. The position of the start point
on the end face of the workpiece is determined
automatically. It can subsequently be changed
manually, however.
END–PTZ : Absolute Z coordinate of the end point for center
drilling or chamfering. End point Z, used for
chamfering, is determined automatically.
Pressing the [DEPTH] soft key enables the depth of a
hole, relative to the start point, to be input.
TOOL–NO : Tool ID number for center drilling or chamfering
For starting, a drill having a tip angle of 90° is
determined automatically.
For center drilling, a center drill having a tip angle of
60° is selected automatically.
In center drilling plus chamfering, a center drill
having a tip angle of 90° is determined automatically.
T–CODE : T code for the tool described above
CUT–SPD : Cutting speed
The actual spindle speed is calculated from the
circumferential speed and nominal diameter of the
tool.
Pressing the [SPINDL SPEED] soft key enables input
of the spindle speed.
FEED/REV : Feedrate
DWELL : Dwell at the bottom of a hole
Data items other than those described above are displayed on the detail
data screen in the same way as those for bar machining.
