About Us
Machining Calculator Hub is an independent educational machining calculator website for CNC programmers, machinists, manufacturing engineers, students, and shop owners.
What we build
We build practical calculators and reference charts for speeds and feeds, milling, turning, drilling, threading, material weight, unit conversions, and machining setup planning.
Accuracy policy
Our formulas are based on common engineering relationships and public technical references. When a result depends on a standard, material grade, tool coating, or proprietary manufacturer data, the page marks it as an estimate and recommends verification.
Independence
This site is an original implementation. It does not copy proprietary databases, paid algorithms, brand grade tables, or page designs from third-party websites.
