Is there a parameter on a Fanuc O-TC that will let me change on the Program Check screen where it says "ACT.F ##.## INCH/M" to read Inch/Revolution?
Thanks

the ACT.F reading is set at 'per minute' and can't be changed. That's one of the things you don't get with the cheaper 0-series controls. On 15/16/18 there is another item that shows actual feed/rev when the feed rate override knob is changed plus or minus.
The cheaper controls show FEED/REV but it's only the programmed feed rate. If you override it the ACT.F changes (which of course is not helpful because it's feed/minute) but FEED/REV stays the same as per the programmed feed rate.
I believe this is the same for 21-series as well.
In any case, it's simple to work it out from your programmed feed rate. work out 10% of your programmed feed rate and multiply it by how many 10-percents you increased or decreased and add/subtract to your programmed feed rate.
example: programmed feed is 0.012 and over ride is + 20%
0.012 / 10 = 0.0012 (i.e. move decimal point one place to the left)
0.0012 * 2 = 0.0024
0.0024 + 0.012
= 0.0144
Doing it this way these calcs can be done in your head, no calculator is required.
Then simply update your program with this feed rate
You can change the display on 0i 18i 21i and 32i controls by changing parameter 3191 bit 5 and 3107 bit 3 both to a 1.
Ah yes good catch! But not all of the manuals for each model have the information listed. That's why I initially said it wasn't possible.
But researching it further.....
In my 21i-A manual there is no listing for parameter 3191 and 3107 bit 3 is blank (undocumented)
However in my 21i-B manual parameter 3191 is indeed the correct parameter but it is listed as bit 0
3191 Bit 0 (FPS)
The unit function (feed per revolution) for actual cutting feedrate display
displays numerals of:
0 : Feedrate per minute.
1 : Feedrate per spindle revolution.
In the same manual the description of bit 3 of parameter 3107 is blank (undocumented)
This may also apply....
3116 Bit 4 (FOV)
In the field of specified feedrate F on the program check screen,
0 : The specified feedrate is displayed.
1 : (Specified feedrate) x (override) is displayed.
In my 0i-D manual 3191 bit 0 is undocumented.
In my 0i-C manual it says......
3191 Bit 0 (FPS)
The unit of values in the display of actual speeds in feed per
revolution mode is:
0 : Feedrate per minute.
1 : Feedrate per spindle rotation.
This parameter is valid when bit 3 (REV) of parameter No. 3107 is set
to 1.
In the same manual.....
3107 Bit 3 (REV)
The actual speed in feed per revolution mode is displayed in:
0 : MM/MIN or INCH/MIN.
1 : MM/REV or INCH/REV.
I think possibly 3191 bit 0 and 3116 bit 4 and 3107 bit 3 all need to be set to '1' to solve the 'Actual Feedrate' display problem.
a quick update on this....
it doesn't work. it may work for some machines depending on system software revision but on my 21i-TA even with all 3 parameters set to 1 it doesn't do anything.
