Type of machining for technology database access: tapping
Cycle run
1 Position spindle to spindle angle C (in Manual mode, machining
starts from the current spindle angle)
2 If defined, move at rapid traverse to starting point of hole Z1
3 Tap thread to hole end point Z2
4 Retract at return speed SR
 If Z1 is programmed, to hole starting point Z1
 If Z1 is not programmed, to starting point Z
5 Move to the tool change point according to the G14 setting
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 Displays which workpiece spindle is used to process the
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
The CNC PILOT uses the tool parameter driven tool to
determine whether the programmed spindle speed and
feed rate apply to the spindle or the driven tool.
