Manual lathe feed calculation update - Swarf_Newbie - 02-26-2019
Further to my thread on changing feedrates, I have managed to knock up an Excel thingymabob to do some of the work for me.
Could one of this forums Guru's have a look as I can't get the Imperial thread calcs right.
The metric calcs work as does the travel feed rate calcs.
Any help would be immensely and gratefully received.
Cheers.
Roy.

Sorry, but one of the things I don't miss about working is trying to figure out Excel.
