4. DESCRIPTION OF PARAMETERS
65
When the machine requires little change in cutting feedrate during
cutting, a cutting feedrate can be specified in the parameter. This
eliminates the need to specify a cutting feedrate (F command) in the NC
program.
The cutting feedrate set by this parameter is valid after the CNC is placed
in the clear state by power–up or a reset until a feedrate is specified by a
program command (F command). After a feedrate is specified by the F
command, the feedrate becomes valid.

Specify the maximum cutting feedrate.
A feedrate in the tangential direction is clamped in cutting feed so that it
does not exceed the feedrate specified in this parameter.
