2.6 “F” WORK FEED
Function F (Feed) defines the work feed and can have two different significances, according to which
preparatory G function is active (G95 or G94 see par. 3.6 and par. 3.7):
mm/rev (usually used for turning operations).
mm/min (usually used for milling operations or for work movements with spindle stationary).
The programmed feed F can be modified through the axis trimmer with a variable value from 0% to 120%.
The programmed feed F remains active until another is selected.
2.7 “S” SPINDLE ROTATION SPEED
Function S (Speed) defines the rotation speed of the spindle. It can have two different significances,
according to which preparatory G function is active (G97 or G96 see par. 3.8 and par. 3.9):
rpm (usually used for machining without wide diameter variations e.g.: drilling, tapping and
thread cutting).
m/min (usually used for all turning operations).
The programmed speed can be changed through the spindle trimmer with a variable value from 50% to
120%.
