Re: [CAD_CAM_EDM_DRO] Newbie Question - speeds and feeds

Eric,

I put a spreadsheet I created to accomplish the same things you want in the
following location:

http://groups.yahoo.com/group/CAD_CAM_EDM_DRO/files/Math/End mill
calculator.xls

This should handle what you're looking for and is customizable - feel free
to add to it as you see fit.

Another option is a free program called Cimco Speed and Feed Calculator:

Good Luck!

James
