3.2 Creating and Writing Programs
Possible feed rate input
Functions for setting the feed rate Soft key
Rapid traverse, non-modal Exception: If defined
before an APPR block, FMAX is also in effect for
moving to an auxiliary point(see “Important
positions for approach and departure” on page
210).
Traverse feed rate automatically calculated in
TOOL CALL.
Move at the programmed feed rate (unit of
measure is mm/min or 1/10 inch/min). With
rotary axes, the TNC interprets the feed rate in
degrees/min, regardless of whether the program
is written in mm or inch
With FT, instead of a speed you define a time in
seconds (input range 0.001 to 999.999 seconds),
in which the programmed path is to be traversed.
FT is effective only blockwise
With FMAXT, instead of a speed you define a time
in seconds (input range 0.001 to 999.999
seconds), in which the programmed path is to be
traversed. FMAXT is effective only for keyboards
with a rapid traverse potentiometer. FMAXT is
effective only blockwise
Define the feed per revolution (units in mm/rev or
inch/rev). Caution: In inch-programs, FU cannot
be combined with M136
Define the tooth feed (units in mm/tooth or
inch/tooth). The number of teeth must be defined
in the tool table in the CUT. column.
Functions for conversational guidance Key
Ignore the dialog question.
End the dialog immediately.
Abort the dialog and erase the block.
