5. FEED FUNCTIONSPROGRAMMING
55
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 from 0% to 150% (in 10% steps) can be applied to feed per
minute with the switch on the machine operator’s panel. For detailed
information, see the appropriate manual of the machine tool builder.
