Cutting Time Calculator

CORE CNC

Estimate machining time for a single feature or pass from cut length, feed rate, and number of passes.

—
Cutting Time (min)
—
Cutting Time (sec)

Formula: Time = (Cut Length times Number of Passes) divided by Feed Rate.

How it works

This is the basic time-in-cut estimate. It does not include rapids, tool changes, or dwell, just the time the tool is actually feeding through material across all passes.

FAQ

Does this include rapid moves between passes? No, this is cutting time only. Add rapid/positioning time separately for a full cycle time estimate.
