How to use this tool

  1. Enter every input in the labeled units; use measured or independently specified properties.
  2. Check the stated model assumptions before calculating.
  3. Interpret the output as a model estimate and verify it independently for the intended application.

{
  "uncut": 0.1,
  "chip": 0.2,
  "rake": 10
}

Accuracy and scope

Orthogonal single-shear-plane cutting idealization; measured chip must represent a steady continuous chip. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
