CNC stands for Computer Numerical Control. A CNC machine performs movements and operations according to a prepared digital program, allowing components to be manufactured accurately and repeatedly with less manual intervention.
How does a CNC machine work?
The operator first creates or imports a digital design. CAD/CAM software is then used to prepare toolpaths and machining parameters.
The resulting CNC program contains commands for axis movements, feed rates, spindle speed, tool changing and other functions. The CNC controller processes these commands and coordinates the machine.
Basic CNC workflow
-
Create or import the design.
-
Prepare toolpaths in CAM software.
-
Select the cutter and cutting parameters.
-
Secure and align the material.
-
Set the work zero point.
-
Check and start the CNC program.
-
Inspect the completed part.
Correct program preparation, tooling and workholding remain essential even when the machining process is automated.
Common CNC machine types
-
CNC routers and milling machines,
-
CNC lathes,
-
CNC plasma cutting machines,
-
CNC lasers,
-
CNC grinding machines,
-
oscillating-knife cutting machines,
-
specialised multi-axis machines.
Which materials can be processed?
Depending on the machine, CNC technology can process wood, MDF, plywood, plastics, composites, foam, aluminium, steel, non-ferrous metals, stone and many other materials.
No single CNC machine is suitable for every material. Machine construction, rigidity, power, tooling and the chosen manufacturing technology determine what can be processed effectively.
Benefits of CNC technology
-
high accuracy and repeatability,
-
production of complex shapes,
-
improved productivity,
-
fewer manual operations,
-
easy repetition of completed products,
-
suitability for one-off and serial production.
