Resources for people who have to decide something this week.

Definitions that match the standards, methods explained without jargon, and free calculators that do the arithmetic. No sign-up, nothing stored.

Reference material for people who have to make a decision about a machine this week: how the standard definitions actually work, what a measurement means once you have it, and free tools that do the arithmetic without asking for an email address.

Everything here is written by the team that runs the platform. Where a figure comes from an external standard or a published industry benchmark, we say so and name the source.

Definitions and standards

The vocabulary that causes the most avoidable arguments in Indian plants.

STANDARDOEE, defined to ISO 22400-2Availability, Effectiveness and Quality as the standard defines them — and how the MachineWise variant differs.CALCULATOROEE calculated two waysThe ISO formulation side by side with the time-in-cut variant, each loss priced separately.METHODCondition-based monitoringWhat CBM actually requires: baselines per machine rather than handbook thresholds.METHODBooked, worked and free hoursWhy utilisation and OEE answer different questions and should never be quoted interchangeably.

Vibration and machine condition

Turning a number on a meter into a decision about a machine.

Questions

Straight answers.

Are the calculators really free, with no email required?

Yes. All four run entirely in your browser, nothing you type is transmitted, and the result appears before any form is offered.

Which OEE definition should I quote to a customer?

The ISO 22400-2 definition, always, and say so explicitly. The MachineWise time-in-cut variant is useful internally because it needs no ideal cycle time, but it is not comparable to ISO-based benchmarks and should never be presented as one.

Is the bearing calculator accurate for my specific bearing?

It is accurate for the geometry you give it. Nominal geometry differs between manufacturers for the same designation, which is why every value is editable and why the page tells you to verify against your bearing's datasheet for anything critical.

Do you publish the ISO standards themselves?

No. We compute against the evaluation zones and explain what they mean; the standards are published by ISO and should be purchased for compliance work.

How often is this material updated?

Reference pages are updated when the underlying standard or our platform behaviour changes. Field notes are added as deployments produce something worth writing up.

Can I use these pages in internal training?

Yes, freely. If you reproduce a calculator's output in a report, state which OEE definition it used — that single line prevents most downstream confusion.
