Feedrate per revolution (G95)

G95 Feed rate in mm/revolution (modal)

During turning with active G95 a constant chip-thickness can be fixed using the F-Word in mm/rev, irrespective of the spindle speed (rpm).

The feed of the axes, thereby, is coupled to the rotational speed (rpm) of the position-controlled spindle. It is valid only in conjunction with the G-function at which it had been programmed. In case of a change from G95 to G94 or G93, thus, the F-word, valid for G95, is not adopted.

Programming example

N10 F1000 X100 M3 S1200 (Feed 1000 mm/min (G94))
N20 G95 F1.5 (Feed 1.5 mm/rev., spindle speed 1200 1/min)
N30 G94 X50 (Feed 1000 mm/min from N10 is valid)
N40 G93 F20 X20 (Machining duration 20 s) 
N50 G95 Y200 S2000 (Feed 1.5 mm/rev. from N20 valid,)
(spindle speed 2000 1/min)
N60 M30
