Re: Export tracking on Fanuc 31i.
hy there are 2 things to consider : frequnecy at which you gather data, and reaction
low frequency, like seconds, etc is like a timestamp, you can check cycle time consistency
0.1seconds is for code variants consitency, going for improvements
0.01seconds is for controler stuff, like different set of parameters, without chainging the code
<1/1000 is live servo data
reaction is if you decide something and implement from outside, or build inner logic within the machine program
record production parameters
for cycle time consistency, you should simply at 1st be sure that your programs are stable at 100% override; once stability is achieved, decide your next move
Are there variables in the CNC that directly return the values of spindle load, axis load, real spindle rotation, real feed rate
i am not a fanuc guy, so i can't provide specific controller advice
yet i can do such things on okuma ... spindle rotation and feed consistency can be checked by cycle time analysis; some programers preffer to disable input from potentiometers, as to be sure that the operators won't use the override ...
loads, promising as they are, are much more tricky and chalenging; at 1st you should scan for peaks, to avoid axis shocks, thus ensure smooth motion ... once all ok, develop futher / kindly
