7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
375
After specifying G95 (G99 for T series) (in the feed per revolution mode),
the amount of feed of the tool per spindle revolution is to be directly
specified by setting a number after F. G95 (G99 for T series) is a modal
code. Once a G95 is specified, it is valid until G94 (G98 for T series) (feed
per minute) is specified.
An override of between 0 and 254% (in steps of 1%) can be applied to feed
per rotation, using the feedrate override signals (*FV0 to *FV7). (See
Subsection 7.1.6.2.)
