Feedrate F

Functionality
The feed F is the path velocity and represents the value of the geometric sum of the velocity
components of all axes involved. The individual axis velocities therefore result from the
portion of the axis path in the overall distance to be traversed.
The feedrate F is effective for the interpolation types G1, G2, G3, CIP, and CT and is
retained until a new F word is written.

Note
For integer values, the decimal point is not required, e.g. F300.
Unit of measure for F with G94, G95
The dimension unit for the F word is determined by G functions:
● G94: F as the feedrate in mm/min
● G95: Feedrate F in mm/spindle revolutions
Programming example
N10 G94 F310
...
N110 S200 M3
N120 G95 F15.5
Note
Write a new F word if you change G94 - G95.
240
(only meaningful when the spindle is running)
Note
This unit of measure applies to metric dimensions. According to Section "Metric and inch
dimensioning", settings with inch dimensioning are also possible.
; Feedrate in mm/min
; Spindle rotation
; Feedrate in mm/revolution
