    Post Reading spindle load from HEIDENHAIN controller

    I need to record the value of the spindle load during the cut on my Quaser ux600 with the HEIDENHAIN controller (TNC640).
    I rather record it somehow synchronized with an external accelerometer using a NI-PXI, yet, I am open to any online method of reading and storing spindle load.
    I am working on it for a while and so far I have no clue how to do it. I would really appreciate it if someone can help me.

    hy hudson ... i have used load diagrams on okuma machines, in order to improve process stability, etc

    the controler can display such a diagram, for example, is possible to see how spindle load evolves for 60 seconds, then the diagram is refreshed

    i have also used ocr software with ping80-100ms to record axis data, including load, actual position and theoretical position; to reach a ping<1ms, you need to gather data directly from the servos ( i guess an electronist could do it )

    unfortunately, i dont have experience with heidenhain is it running on windows, or other OS ?

    i also don't know what an externall accelerometer is, so i also can't undersand how you wish to use it

    please, what do you wish to achieve ? kindly

    Hi HudsonMachines,

    This is a very interesting question- I will ask the team at Heidenhain for some info on this and get back to you.

    Most machine events are located in a logbook file- however spindle/axis load history is usually not saved in the older controls (I do not have a TNC640- mine are all older)

    However from what I remember, TNC 640 has a beautiful feature where in the machine automatically increases feedrate when spindle load is below a set point in order to improve machine efficiency and improve MRR- I am not sure if this is a standard feature or optional feature. As a result of this feature being there, I am of the assumption that the data should be logged for the controller to compute the changes needed.

    I will try to get back with more information once available.

    Best regards

    Jaideep
