The lean-stack take

For a lean team it turns machine run and stop signals into utilization, downtime and OEE data. Teams can use this data to find the biggest losses and focus improvement work on them.

Best for

Small and mid-sized machine shops and discrete manufacturers that want to measure machine utilization and downtime.

Watch out for

Check how the monitoring hardware connects to your machine types and power supply before committing.

Features

What FourJaw offers

Machine monitoring hardware

FourJaw describes a plug-and-play monitoring system that connects to machines, including CNC machines, to capture run and idle time without a full integration project.

OEE monitoring

An OEE monitoring feature tracks overall equipment effectiveness, which supports loss analysis and TPM work.

Downtime reasons on tablets

Operators record downtime reasons on a tablet, and a help article covers a tablet downtime auto-labeller. This builds a Pareto of stop reasons.

Production monitoring

A production monitoring page covers live machine status and productivity, which supports visual management and daily shop floor reviews.

Planning and communications

Planning features connect monitoring data to production planning, so plans can reflect actual machine capacity.

Job tracking

The 2.2 product release added job tracking and data management features, linking machine time to individual jobs.

Energy and sustainability

Sustainability features show machine energy use, so teams can spot waste such as machines left running while idle.

API

The help center documents a FourJaw API, so data can flow to other systems such as ERP or BI tools.
