Feedrate F
Fu n ctionality
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.
Programming
F...
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
(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.
Programming example
N10 G94 F310
; Feedrate in mm/min
N110 S200 M3
; S pindle rotation
N120 G95 F15.5
; Feedrate in mm/revolution
Note
Write a new F word if you change G94
- G95.
11.3.3
Linear interpolation with feedrate: G1
Fu n ctionality
The tool moves from the starting point to the end point along a straight path. The
path velocity
is determined by the
programmed
F word
.
All axes can be traversed simultaneously.
G1 remains active until canceled by another instruction from this G group (G0, G2, G3...).
Programming
G1 X... Y... Z... F...
; Cartesian coordinates
G1 AP=... RP
=... F...
; Polar coordinates
G1 AP=... RP=... Z... F...
; cylindrical coordinates (3-dimensional)
Note
Another option for linear programming is available with the angle specification ANG=... (see Section "
Contour definition
programming
(Page 110)").
