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
- 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
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.
