What is CNC machine monitoring?
CNC machine monitoring collects operating data directly from CNC machines, automatically, and shows it live: cutting, waiting for parts, in alarm or down for repair, with part counts and lost time for every shift. The same data calculates OEE and shows why machines are not producing at full capacity.
Plants that log by hand usually see one summary number at the end of a shift, written afterwards and without detail, so many short stops never reach the report. Monitoring shows what really happens on the floor, minute by minute.
What a CNC monitoring system collects
Machine status
Run / idle / alarm / stop / setup in real time, with a timeline history.
Output and cycle time
Automatic part counts against hourly and shift targets.
Alarms and stop reasons
Alarm codes from the control, plus stop reasons chosen by operators on screen.
Program and part
The NC program running, the part and the order being produced.
Machine values
Such as spindle load, speed, feed rate and offsets (depending on the control).
OEE
Availability × Performance × Quality per machine, line and shift.
How CNC machines are connected
- FANUC-controlled machines – data read over Ethernet with FANUC FOCAS (depending on control model and options).
- Machines with open standards such as MTConnect or OPC UA – read directly through the standard.
- Older machines without a communication port – tower-light status, I/O signals or an added part-count sensor.
NKE engineers survey every machine first and choose the right connection, so machines of different brands and ages appear in one system.
Benefits
- See the time you really lose – waiting for parts, changeovers, worn tools or alarms, and for how long.
- Decide from data – fix the biggest time losses first instead of guessing.
- Less paperwork – no hand-written output and downtime logs, nothing missed.
- No walking the floor – managers and supervisors see every machine on one screen.
- Build on it – maintenance and production planning, and Auto Offset for part quality.
Getting started with NKE
1 · Site survey
Machine models, controls and the plant network.
2 · Pilot machines
Connect a first group, see real data and tune the screens.
3 · Whole line
Add the remaining machines, set up OEE, stop reasons and reports.
4 · Keep improving
Use the data to fix the floor: jigs, robot loading or Auto Offset.

FAQ
What is CNC machine monitoring?
A system that collects data from CNC machines automatically and shows run, stop and alarm status, output and OEE for every machine in real time, instead of walking the floor or writing logs by hand.
Does it work with older CNC machines?
In many cases, yes. Machines without a communication port can use tower-light status, I/O signals or an added part-count sensor. Engineers survey each model before choosing how to connect it.
Which machine brands are supported?
FANUC-controlled machines connect through FOCAS; machines with MTConnect or OPC UA are read through the standard; others use I/O signals. Send your machine list and our team will check it.
How long are machines stopped for installation?
It depends on how each machine is connected. We plan the installation with your production team to keep the impact as small as possible.
How is CNC monitoring different from OEE?
OEE is the measure; CNC monitoring is the system that collects real machine data so OEE is accurate and the causes of low OEE are visible.
Where can we see the data?
Monitoring systems usually show data on shop-floor screens and office computers. We design the screens, users and access to fit your plant network policy.
