5. FEED FUNCTIONS
The feed functions control the feedrate of the nozzle. The following two
feed functions are available:
1. Rapid traverse
When the positioning command (G00) is specified, the nozzle moves
at a rapid traverse feedrate set in the CNC (parameter No. 1420).
2. Cutting feed
The nozzle moves at a programmed cutting feedrate.
Override can be applied to a rapid traverse rate or cutting feedrate using
the switch on the machine operator’s panel.
To prevent a mechanical shock, acceleration/deceleration is automatically
applied when the nozzle starts and ends its movement (Fig.5.1 (a)).
