CNC Calculator: Speeds Feeds

About

Numbers you need standing at the machine, not at a desk. WHAT IT WORKS OUT • Feed and speed from material, tool and diameter — SFM and RPM, IPM and chip load • Tap drill size for a thread, and the thread data behind it • Taper, angle and offset for turning • Bolt circle coordinates • Unit conversion between inch and metric, including feed units WHERE THE NUMBERS COME FROM Every table shows its source: published cutting-data ranges and standard thread and drill tables. Nothing is invented and nothing is guessed. A range is shown as a range, because that is what the source says — the final call is the machinist's. BUILT FOR THE SHOP FLOOR • Works with no signal • No account, no sign-up • Big numbers, readable with safety glasses on Terms of Use: https://denwee.com/app/cnc_calc/terms Privacy Policy: https://denwee.com/app/cnc_calc/privacy
