How to set CNC machining parameters — cutting speed, spindle RPM, feed rate, chip load and depth of cut — with the formulas, the starting points, a repeatable tuning method, and the recipe each operation actually needs.
Hard milling explained — cutting fully hardened tool and mold steels at 45–65 HRC: why the normal rules of milling stop applying, the three pillars that make it work, when to hard-mill instead of EDM or grind, and the tooling, machine and parameters it demands.
Milling chatter explained — what chatter actually is, how to tell it from resonance hum and rubbing squeal, the four 'springs' that decide which chatter you get, and a fix ladder ordered from the lever that works most often to the advanced ones.
High-efficiency milling (HEM) and trochoidal toolpaths explained — the chip-thinning mechanism behind them, how HEM differs from high-speed machining, which toolpaths do what, and the honest test of when they pay versus when conventional roughing is still right.
CNC speeds and feeds explained from zero — cutting speed vs spindle speed vs feed rate, why SFM stays constant while RPM changes, chip load as the real feed control, and full worked calculations in both imperial and metric.
