Feed rate F and miscellaneous function M
The feed rate F and miscellaneous function M are entered as
separate blocks. They become effective as soon as the TNC has
run the block in which they are programmed.
These blocks must be run before the positioning blocks for which
they are intended.
Entering the feed rate F
The machining feed rate is “modal.” That means that the entered
feed rate remains effective until you replaced it by entering a new
one.
