Impatience is the enemy...or is it the mother of invention?

Have you seen my feeds & speeds page and if so did you turn away because of the math ?

The reason I am asking is because I wrote this after spending countless hours (and a fair number of reading and writing posts in this thread) myself to answer those same questions (or at least find something I would be comfortable using myself)

It looks bad, but it boils down to very, very little math:

And even that is taken care of by the spreadsheet

Basically: pick a tool diameter, pick a material, look-up target chipload, input RPM, boom, get feedrate and DOC

EDIT: but it’s still a coarse grain approach. For figuring out the optimum between two different species of hard wood, then experiment, as @WillAdams pointed out
