Über uns - Feed Rate Calculator
Engineering accuracy, transparent formulas, and accessible CNC calculation tools
Feed Rate Calculator was created to provide CNC machinists, programmers, toolmakers, and students with an uncompromised, mathematically rigorous calculation platform.
Calculation Transparency
We believe engineers should never receive a black-box answer without seeing the underlying mathematics. Every result displays the exact formula, substituted values, and foundational engineering assumptions.
Client-Side Privacy & Speed
All machining calculations execute directly in your browser. Your tooling parameters, cut depths, and program details are never transmitted to external servers.
Engineering Reference Benchmark
Our mathematical formulas align with cutting tool industry standards (including Sandvik Coromant, Kennametal, and Machinery's Handbook conventions) across milling, turning, and holemaking operations.
