Speed & Feed Calculator

Illustrate speed/feed arithmetic using generic preset tables, not validated machine settings. Confirm tool-maker data, material grade, tooling, guarding and machine limits before use.

Generic, unsourced preset values are illustrative only, not operating recommendations. RPM uses SFM × 3.82 / diameter in inches. Feed uses RPM × chip load (and flute count for milling); MRR uses width × depth × feed / 1000. Diameter scaling and modifiers are generic examples. Obtain validated settings from the tool and machine manufacturers.
