1.2.3 Switching between feed per minute mode and feed per revolu-
tion mode (G94/G95)
Before specifying a feedrate command (F), a G code that determines whether the
specified feedrate command is interpreted as feed per minute value or feed per
revolution value should be specified. These G codes (G94, G95) are modal and
once they are specified they remain valid until the other G code is specified. When
the feed mode designation G code is specified, the presently valid F code is cance-
led. Therefore, an F code must be specified newly after switching the feed mode
by designating G94 or G95 command. The initial status that is established when
the power is turned on is set by
