    HELP -- ACME .125 pitch with double start clipped

    I'm not sure on how to program this double start ACME .125 pitch that I asume is with a 8TPI insert, I'm guessing that the feed would be F.250 and each treading lead would have a different starting value (double)

    first start at
    Z.250
    second start at
    Z.500

    the clipping would be the exact same programs but with a grooving tool at much lower RPM...

    please anyone would help.
    thanks

    The second threading cycle should start at 0.375
    The F-value in the threading cycle would be 0.250

    Not quite 'exact same' you want the grooving tool offset half a pitch and it pulls out at the beginning not at the end.
    An open mind is a virtue...so long as all the common sense has not leaked out.
