    Question Pre-Loading force

    Hi,

    I am building a W-EDM and I will make an AB nut for it.

    just like this one

    I was wondering, how could I calculate the preloading force of the spring. I know it must exceed the load of the carriage but how can I calculate it in terms of spring parameters?

    Will be waiting for reply,

    Thanks

    Hi,

    I can't really help but here's a link that might point you in the right direction for "spring parameters".
