Classic machining patents

Below are a few of the machining patents that are relevant to my work and I’ll add to them as I encounter others. I would like to include foundational patents on which machining has been built, especially those that have expired, and perhaps more recent ones that have created fundamental change, but are not exotic. Please send me your recommendations.
