Further to my thread on changing feedrates, I have managed to knock up an Excel thingymabob to do some of the work for me. Smiley-eatdrink004

Could one of this forums Guru's have a look as I can't get the Imperial thread calcs right.  Slaphead
The metric calcs work  as does the travel feed rate calcs.

Any help would be immensely and gratefully received. Thumbsup 

Cheers.
