OEE is the single number factories use to judge a machine, multiplying three losses: availability (uptime vs planned), performance (actual vs ideal speed), and quality (good parts vs total). Because they multiply, a chain of "pretty good" factors yields a mediocre result — 90% × 95% × 99% is only 85%. That 85% is the world-class benchmark.

Governing equation

OEE = A \times P \times Q = 0.90 \times 0.95 \times 0.99 = 84.6%

Reading this result: availability is the weakest link at 90%; because the three factors multiply, lifting the lowest one moves OEE far more than polishing a factor that is already high.

About this simulation

The full OEE tool models a CNC part with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
