feed rate format


Recommended Posts

It's been ages since i've changed one of my posts and I have a new machine to get up and running.

 

Its a heidenhain control (i miss my fanuc) and the one thing I can't quite figure out is the format statement to change the feed rate

 

A feed of 25 output to the machine results in 2.5" per minute feed rate.   How can I get the post to output a 250 instead of the 25...ie multiply the feed rate by 10?

 

appreciate the help

Look at the fmt process above the fmt area. It normally tells you how to break it down.

From MPFAN:

#region Format statements
# --------------------------------------------------------------------------
# Format statements - n=nonmodal, l=leading, t=trailing, i=inc, d=delta
# --------------------------------------------------------------------------
#Default english/metric position format statements
fs2 1   0.7 0.6      #Decimal, absolute, 7 place, default for initialize (:)
fs2 2   0.4 0.3      #Decimal, absolute, 4/3 place
fs2 3   0.4 0.3d     #Decimal, delta, 4/3 place
#Common format statements
fs2 4   1 0 1 0      #Integer, not leading
fs2 5   2 0 2 0l     #Integer, force two leading
fs2 6   3 0 3 0l     #Integer, force three leading
fs2 7   4 0 4 0l     #Integer, force four leading
fs2 9   0.1 0.1      #Decimal, absolute, 1 place
fs2 10  0.2 0.2      #Decimal, absolute, 2 place
fs2 11  0.3 0.3      #Decimal, absolute, 3 place
fs2 12  0.4 0.4      #Decimal, absolute, 4 place
fs2 13  0.5 0.5      #Decimal, absolute, 5 place
fs2 14  0.3 0.3d     #Decimal, delta, 3 place
fs2 15  0.2 0.1      #Decimal, absolute, 2/1 place (feedrate)
fs2 16  1 0 1 0n     #Integer, forced output
fs2 17  0.2 0.3      #Decimal, absolute, 2/3 place (tapping feedrate)

# These formats used for 'Date' & 'Time'
fs2 18  2.2 2.2lt    #Decimal, force two leading & two trailing (time2)
fs2 19  2 0 2 0t     #Integer, force trailing                   (hour)
fs2 20  0 2 0 2lt    #Integer, force leading & trailing         (min)

# This format statement is used for sequence number output
# Number of places output is determined by value for "Increment Sequence Number" in CD
# Max depth to the right of the decimal point is set in the fs statement below
fs2 21  0^7 0^7      #Decimal, 7 place, omit decimal if integer value
fs2 22  0^3 0^3      #Decimal, 3 place, omit decimal if integer value

Find the one for feed and then try to see if you can cheat using fmt, but I would use a multiplier in the post to do this verses messing with the fmt statement.

Colin what do you think would be the best way to go about this request?

Yes, a Global Formula, entered in the 1st column, is probably the best way to handle this. That way your Mastercam File units are correct.

Are you positive the feed is exactly a factor of 10 different? Could it be in Metric mode, rather than inch? 25mm per minute instead of inches per minute, would be .984" of travel, in 1 minute.  Not that I doubt you, just wanted to be sure that multiplying the Feed value by "10" in a Global Formula, is the correct fix.
