### G95 - Feed Per Revolution

G95 (Feed Per Revolution) is a modal G-code that instructs the control to interpret feed commands as mm per revolution (mm/rev) or inches per revolution of the spindle.

# Syntax & Parameters

• G95
• F Value The F value specifies the distance travelled per revolution of the spindle used to calculate the G95 feed rate.
• S Value This specifies the spindle speed used to calculate the G95 feed rate

# Example program

N10 G21
N20 S800 M3
N30 G95
N40 G01 X20 F0.1


The above program code would cause the X axis to advance 10mm for every revolution of the spindle until the X axis reaches 20mm.

The Feed rate will be 80mm per minute

G95 feed rate above is calculated as follows

(Spindle speed) x (Specified feed rate) = G95 feed rate

800 x 0.1 = 80mm

INFORMATION: G96 spindle speed has no effect on the G95 feed rate.
