So I am trying to learn how to cut some threads. I am using a Siemens 840D controller on a fryer easy turn lathe.
I am using the manual thread program.
I would like to cut a 1/2 inch 20 thread or 20 threads per inch
The thread program only gives me the option of inches/rev or inches / min for the feed rate.
It seems a bit absurd to me.
How can I convert 20 threads per inch - > inches per rev?
I dont get it. Tried googling but have not found some simple formula
Can someone lend a hand?
I thought for a second all I have to do was say 1/20 - .05 inches per rev
I tried that and put a pitch gauge on it and its not even close.
I am at a loss
