Field notes
For speeds and feeds, the page describes selecting a material, cutter, and operation before returning spindle speed, feed rate, chip load, material removal rate, horsepower, and torque. It says the formulas appear beneath the results. The listed set also includes true-position, sine-bar, material-weight, and conversion tools; the site says the app works offline and remembers recent inputs.
