BP: Interval time – time span for interruption of the feed
The chip is broken by the (intermittent) interruption of the feed.
BF: Feed period – time interval until the next break
The chip is broken by the (intermittent) interruption of the feed.
MT: M after T: M function that is executed after the tool call T
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.
The control uses the tool parameter driven tool to
determine whether the programmed spindle speed
and feed rate apply to the spindle or the driven tool.
