Programming Basics
1.2 Basics of feed function
An F command specified in the simultaneous 2-axis linear interpolation mode or in
the circular interpolation mode represents the feedrate in the tangential direction.
Example of programming (linear interpolation mode)
G95 S1000 (r/min);
G91 G01 X60. Z40. F0.5;
Fig. 1-1
Example of programming (circular interpolation mode)
G95 S1000 (r/min);
G91 G03 X ... Z ... I ... F0.2;
Fig. 1-2
Notice
An F0 command causes an input error.
S
A feedrate in the X-axis direction is determined by the radial value.
S
A feedrate of a cutting tool per minute (mm/min, inch/min) can be designated by
a numeral specified following address character F.
