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 axis velocities are determined from the share of the
axis path in the overall path.
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.

Remark: 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 inmm/min
●
G95 F as feedrate in mm/rev. of the spindle (only meaningful if the spindle is turning!)
Remark:
This unit of measure applies to metric dimensions. According to Section "Metric and inch
dimensioning", settings with inch dimensioning are also possible.
Programming example
N10 G94 F310
; Feedrate in mm/min
...
N110 S200 M3
; Spindle rotation
N120 G95 F15.5
; Feedrate in mm/revolution
Remark: Write a new F word if you change G94 - G95.
Information
The G group with G94, G95 also contains the functions G96, G97 for the constant cutting
rate. These functions also influence the S word.
