Many lathes have Module and Diametral settings for the gearbox. When it comes to precisely spaced round parts the only things I'm familiar with in regards to Module and/or Diametral pitch are gears, knurls, worms and pulleys. Are the Module and Diametral designations for cutting worms only or are there parts that would be produced on a lathe with the aforementioned designations? Thanks, Eric R Snow
Module & Diametral threads?

For cutting worms, and blanking hobbing cutters. Can't think of any other uses. Cheers Trevor Jones

That would be anything that looks like a screw and meshes with a gear. And the only thing coming to my mind are worms. Looking in a lathe operator's handbook, only worms. Googling, I found that module threads are rarely used for hydraulic fittings.
Trevor's hobs are right too.

Thanks Trevor. That's all I can think of too. Eric
I thought so. Thanks. ERS
