After the holes are drilled the turret should be positioned
to index the turret
G28 U0. W0. (SENDS TURRET HOME)
It is important to place a G7 at the beginning of any live
tool operation to program in radius mode, if this isn’t done all x
number will need to be doubled.
It is equally important to return to G8 after the features
are cut that way if a turning process follows milling the turning
can be programmed in diameter.
When programming a lathe it is also important to program
in Feed Per Rev if possible. The advantage to this is the spindle
will give feedback as to what the RPM is and calculate the IPM
from there. The biggest advantage to this is if a spindle were to
stall, the machine will recognize that the spindle has slowed or
stopped and adjust the feed accordingly. On milling tools this is
not acceptable because they normally have multiple flutes,
however for all drilling, tapping, and turning all feed rates
should be in Feed Per Rev.
The next step will be to mill to flats on the side of the part
using cutter comp.
