Haven’t yet been able to wrap my mind around the Jupyter notebooks, but did hit upon another way to present this data, so got started w/ a chart which lists feeds and speeds in rows and columns and materials at the intersections — since one can do a textual search, one can pull up where things are, and I think it’s interesting to see adjacent materials &c.

I think it’ll be useful at least for extrapolating feeds and speeds for similar materials, and evaluating them to determine if they make sense. Entering the 1/8" endmill values to start, and will be putting in as much from the Materials page as will fit — we’ll see how it works out.
