Sorry ,I completely forgot to mention that the i need to calculate the flat size for ACME thread gauges.The machinery handbook contains information about ACME thread,not the GAUGES.

RE: ACME threads

(OP)
Tnx dear KENAT.I looked in the ASME standard,B1.5 1997,
But there was nothing explaining the calculation method of ACME thread gauges flat size.

RE: ACME threads

Hang on, by flat size do you meant the flats at the crest and trench of the threads - or are you talking about rolling the gauge from a flat piece of material or something?

If the former, I'm surprised if it's not in the standard - at least implicitly.

RE: ACME threads

If your time is valuable, software is available that will make those calculations quickly and accurately.
