3.6 “G95” FEED IN MM/REV
The G95 function selects the feed F in mm/rev. When this function is active the feed values will be
programmed as follows: F0.05, F0.15, F0.3, F0.5 and so forth. G95 is automatically activated when the
machine is switched on, therefore it is not necessary to specify its activation in the program. It is a modal
function and can be cancelled by programming code G94.

3.7 “G94” FEED IN MM/MIN
The G94 function selects feed F in mm/min. When this function is active the feed values will be
programmed as follows: F50, F150, F500, F2000 and so forth. This function is used to perform
movements with work feed when the spindle is stationary, or when it is necessary to release the axis feed
from the spindle revolutions (e.g.: when milling with motor driven tools). G94 is a modal function and can
be cancelled by programming the code G95.
