trapezoidal thread

[Nioh17]

hello to all, I am new in the craft of mechanical designer. I happen to have to do a trapezoidal thread to adjust a race. studying the thread I found that there are tables regarding the steps for each diameter. for work needs in the design I am doing would need a much smaller step on a tr30x6, for example a tr30x3. I have not found information at the standard iso level on the possibility to freely change the step and if it is possible to perform the processing (with the craft tools) and then insert as a step 3 for a diameter tr30.
Thank you.

what you ask is trapetidal thread 30 fine step. (3mm)
on any vademecum (e.g. baldassini) find information.

you summarize main parameters tr30x3

Thank you.

But do you really think that by exhorting you to do it yourself they are doing you a disrespect?

No no, but if it's good if I do it alone like he said who does it for three

If you know the theory you have the possibility to set the spreadsheet as you think, adapting it and enriching it with what you need. and above all you remain in mind as you do, reasoning in short.
