Hey I have a feed / speed spreadsheet too! : https://discuss-assets.s3.amazonaws.com/original/3X/9/8/988930d2ef4c574b732dd258e048fa8cbaac63f7.xls
you can read about it here. Repeatable process for setting Feed Rate and Depth of Cut in Easel and elsewhere
making one of these is starting to feel like a rite of passage,
like breaking in a new glove,
or calculating the trajectory book for your new howitzer…
am I naieve to think someday we may get to a single canonical version of one of these…?
