Metalworking wall charts part two

It took a little longer to make, but I finished up a lathe speed chart tonight. I set this chart up as an excel spreadsheet so you can customize it. The spreadsheet accepts two control parameters feed, & doc (see cells K1 & K2). Doc has 5 possible settings 1.0″, 0 .4″, 0 .2″, 0.1″, 0.04″. Feed allows for any value from 0.002″ – 0.038″.

Please note that at the higher feed settings some cells will display¬† “N/A”.¬† The data I pulled from the “Machinery’s Handbook” has a small range, thus I decided it was better to provide no speed when a calculated value fell out side the range. I also preformatted the spreadsheet for printing on 3 letter sized sheets of paper.
