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