Feedrate F - Siemens sinumerik 808d Programming And Operating Manual

Programming principles
1.3 Axis movements
Note
Another option for linear programming is available with the angle specification ANG=. (For
more information, see the topic "Contour definition programming (Page 70)".)
Information
Another group of G functions exists for moving into the position (see the topic "Exact stop /
continuous-path control mode: G9, G60, G64 (Page 50)"). For G60 exact stop, a window
with various precision values can be selected with another G group. For exact stop, an
alternative instruction with non-modal effectiveness exists: G9.
You should consider these options for adaptation to your positioning tasks.
1.3.2

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. Refer to the sections Linear interpolation with feedrate:
G1 (Page 37) and Circular interpolation: G2, G3 (Page 38) to learn more information.

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 in mm/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.
