Laser cutting shop
In a laser cutting shop, what the machine does and what it costs

The scope
What is measured
- Sector
- Laser cutting
- Instrumented machine
- Laser cutting machine
- Measured quantities
- Cutting machine vibration
- Electrical energy used
- Detected events
- Running, production and stoppages
- Daily run rate
- End of run with no operator
- OEE broken down, each figure with its source
- Achieved result
The machine’s energy cost in euros, estimated on a tariff assumption, and an OEE where each figure has its source. What the measurement asked of the shop’s IT network: 0 access requested. The unit reports over LTE-M, on its own SIM card.
The deployment
Control points
Equipment : Cutting machine
What is measured : The Sybox fitted on the machine, without touching the PLC.
What it showed : Running, production and stoppages are told apart, day after day.
Equipment : Energy
What is measured : Energy used by the machine, read continuously.
What it showed : A monthly electricity cost, estimated on a tariff assumption.
What the machine does, what it costs, and where each figure comes from, without touching the PLC.
Reading still to come
This deployment has no published figures yet: daily run rate, monthly electricity cost, OEE breakdown. The cost is an estimate on a tariff assumption, not an invoice. The commissioning date and the observation period are missing too.
Those values exist on the customer’s side and must be approved by them before publication. This site publishes no gain figure without a source; the panel will stay as it is until then.
In operation
What it changed
- Energy cost is read in eurosWhat the machine costs is read apart from the rest of the shop.
- An end of run with no operator has a costIt shows, and can be decided with full knowledge.
- OEE is broken downEach figure of overall equipment effectiveness says where it comes from.
In this shop, knowing whether the cutting machine was running was not enough: the question was what it does, what it costs, and where each figure comes from.
The installation touched neither the machine’s PLC nor the shop’s IT network: the Sybox sends its readings over the cellular network.
