OEE Software · ISO 22400-2

OEE, computed by the machines themselves.

Most plants calculate OEE once a month, from a spreadsheet, two weeks late. MachineWise reads the signals your machines already produce and computes Availability × Performance × Quality live, with every stop timestamped and every loss attributed.

Why spreadsheet OEE fails

Manual OEE tracking is always late and always generous.

Late

The report that arrives after the month

Monthly OEE describes a month nobody can change any more. Too late to fix anything, too aggregated to point at anything.

Disputed

Whose number is right?

Production says 78%, planning says 61%. When OEE comes from machine signals there is one number, and it is nobody's opinion.

Hidden

Averages bury the worst machine

A plant-level 65% hides the machine at 31%. Machine, shift and part-level OEE shows where the loss actually lives.

The six big losses

Every loss has a place. MachineWise captures each one automatically.

The classic loss tree, and how each loss gets into the numbers without anyone writing it down. The full explanation is in the six big losses.

Availability loss

Breakdowns

Unplanned stops from failures.

Detected from machine signals to the second, reason tagged at the machine.
Availability loss

Setup and changeover

Time from last good part to first good part.

Setup captured as its own state, separate from breakdowns.
Performance loss

Minor stops

Short stops too brief for anyone to log.

Every micro-stop recorded automatically, so it adds up in the Pareto.
Performance loss

Reduced speed

Running slower than the ideal cycle.

Cycle time against the best demonstrated cycle for that part.
Quality loss

Startup rejects

Scrap while the process stabilises.

Rejects logged against the machine state at that moment.
Quality loss

Production rejects

Scrap and rework in steady running.

First-pass yield trended by machine, part and operator.
Drill down

From the boardroom number to the reason, in four clicks.

A plant average tells you something is wrong. The drill-down tells you what, where, when and why.

Definitions

Which OEE are we talking about?

Two definitions circulate in Indian plants. MachineWise computes both and labels them, so nobody quotes one while the customer means the other.

ISO 22400-2 · the standard

The definition to quote externally

Availability = actual production time ÷ planned production time
Performance = produced qty × ideal cycle time ÷ actual production time
Quality = good qty ÷ produced qty

Requires a maintained ideal cycle time for every part. The right figure for customer audits and benchmarks. Full reference: ISO 22400-2 definitions.

The MachineWise variant · disclosed

What a machine can answer without standards

Availability = machine on-time ÷ reporting time
Performance = productive time ÷ machine on-time (time-in-cut proxy)
Quality = approved parts ÷ parts produced (same as ISO)

Needs no ideal cycle time, so it works on short and mixed batches from day one. It is never presented as the ISO figure or compared with ISO-based benchmarks.

How it works

From machine signal to a number you can act on.

01

Connect

Native drivers for CNCs and PLCs, gateways for machines with nothing to read. Under an hour per machine.

02

Classify

Every second becomes running, idle, setup or breakdown, automatically.

03

Explain

Operators tag stop reasons at the machine in two taps; rejects are logged at source.

04

Compute

A × P × Q per machine, shift, part and operator, to ISO 22400-2 and the disclosed variant.

05

Act

Paretos, TV walls and WhatsApp shift summaries put the biggest loss in front of the right person.

Questions

Straight answers.

What is OEE?
OEE (Overall Equipment Effectiveness) is the share of planned production time that is truly productive: Availability × Performance × Quality. 100% means only good parts, as fast as possible, with no stops. The standard definitions are in ISO 22400-2.
How is OEE calculated?
Availability = run time ÷ planned time. Performance = (parts × ideal cycle time) ÷ run time. Quality = good parts ÷ total parts. Multiply the three. MachineWise does this continuously from machine signals, so no one fills in a spreadsheet.
What is a good OEE?
85% is often quoted as world class, but that figure assumes a stable, high-volume process. Most Indian job shops measured automatically start well below it. A good OEE is one that is measured honestly and rising; see what is a good OEE.
Why does automated OEE come out lower than our manual figure?
Manual OEE misses minor stops, rounds downtime to the nearest convenient number and often uses a generous ideal cycle time. Machine signals record every stop to the second. The lower number is the true one, and it points at losses the manual figure hid.
Does OEE need operators to enter data?
Availability and Performance come from machine signals with no data entry. Operators add the reason for a stop, which takes two taps at the machine, and rejects are logged at the machine for Quality.
Which machines can MachineWise measure OEE on?
CNC machines, PLC-driven machines, presses, moulding machines, furnaces and conventional machines with no controller, connected by the MachineWise team, with MachineWise gateways for machines that have no controller.
How quickly will we see live OEE?
Software-first setup takes under an hour per machine, so live OEE usually appears the same week. The free 2-machine pilot is designed to show it on your own floor within days.
