MFS : M at beginning : M function that is executed at the
beginning of the machining step
MFE
:
M at end
:
M
function that is executed at the end of the
machining step
WP : No. of spindle – Displays which workpiece spindle is used
to execute the cycle (machine-dependent)
Main drive
Opposing spindle for rear-face machining
BW : Angle in the B axis (machine-dependent)
CW
:
Reverse the tool
(machine-dependent)
HC : Shoe brake (machine-dependent)
DF : Miscellaneous function (machine-dependent)
Type of machining for technology database access
depends on the tool type:
Drillg for twist drills
Predrilling
with indexable insert drills
If
AB
and
V
are programmed, the feed rate is reduced by
50 % during both pre-drilling and through-boring.
Cycle run:
1 Position the spindle to the
Spindle angle C
(in
Machine
mode:
machining from current spindle angle)
2 If defined, move at rapid traverse to the Start point drill X1
3 If defined, spot drill at reduced feed rate
4 Depending on
Drilling variants V :
Through-drilling reduction:
Drill at programmed feed rate to position X2 – AB
Drill at reduced feed rate to
End point drill X2
No through-drilling reduction:
Drill at programmed feed rate to End point drill X2
Remain at end of hole for Period of dwell E if defined
5 Retract
If
X1
is programmed, to
Start point drill X1
If X1 is not programmed, to Start point X
6 Move to the Tool change point according to the setting in G14
