7.1.4 Feed per Revolution/Feed per Revolution without Position
Coder
Overview
- Feed per revolution
Specify G95 (feed-per-revolution mode), then directly specify a
numeric value, preceded by F, to indicate the amount by which the tool
is to be fed per rotation about the spindle. G95 is modal; once it is
specified, it remains effective until G94 (feed-per-minute mode) is
specified. Feedrate overrides can be applied to feed per revolution, in
the same way as feed per minute.

- Position-coder-less feed per revolution
For a machine without a position coder (or a machine that does not use
one), the feedrate specified in feed-per-revolution mode is converted
into a feedrate per minute, assuming that the spindle rotates under the
control of the spindle speed command (S code), and that tool is moved
along the feed axis at that rate.
