Fig.5.3 (a) Tangential feedrate (F)
- Feed per minute (G94)
After specifying G94 (in the feed per minute mode), the amount of feed
of the tool per minute is to be directly specified by setting a number
after F. G94 is a modal code. Once a G94 is specified, it is valid until
G95 (feed per revolution) is specified. At power-on, the feed per
minute mode is set.
An override can be applied to feed per minute with the switch on the
machine operator’s panel. (See II-5.3.1)
For detailed information, see the appropriate manual of the machine
tool builder.
