Flank Wear — Remaining Life Estimator
Linear-zone projection of remaining minutes until the VB wear limit from two wear measurements.
Carbide wear runs in three acts: fast break-in, long linear middle, runaway end. Two measurements in the middle act predict the cliff well — but stop trusting the line beyond ~0.25 mm VB, where the runaway zone begins.

About Flank Wear — Remaining Life Estimator
Flank Wear — Remaining Life Estimator computes the governing relationship VB(t) linear in steady zone → t_rem = (VB_max − VB₂)/(dVB/dt) live as you type. Carbide wear runs in three acts: fast break-in, long linear middle, runaway end. Two measurements in the middle act predict the cliff well — but stop trusting the line beyond ~0.25 mm VB, where the runaway zone begins. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Flank Wear — Remaining Life Estimator
- 1Enter your values — Wear at first check, Cut time at first check, Wear at second check, Cut time at second check and more (sensible defaults are pre-filled).
- 2Read the live results: Wear rate, Remaining life, Projected total life.
- 3Check the "with your numbers" line to see VB(t) linear in steady zone → t_rem = (VB_max − VB₂)/(dVB/dt) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
