A CNC machinist math cheat sheet covers the formulas you actually use: speeds and feeds, basic trig, and bolt circles. Here is what to include and the real limit.
Day-to-day CNC programming runs on arithmetic, not calculus: offsets, two formulas, and direction sense. Which math you can dodge and which to keep.
Chip load connects tool data to the F word: compute feed forward from chip load, audit any program in reverse, or let macro variables do it in the code.
