CNC Essential Info


What is CNC Routing?

A CNC Router is a computer controlled machine that has a mounted spindle, which holds a cutting tool. It is typically set up with 3 directions of movement referred to as the X, Y and Z axis. This allows the machine to cut in 3 Dimensions.

CNC machining is a subtractive process. Starting with a block of material the cutting tool cuts away the material that is not needed. This material is extracted to a collection bag outside.

CNC Routers can cut 2D Files (for Example: Flat pack furniture) and 3D Files (for example: Landscapes)

We have 2 CNC Routers in the 3D Workshop

The ISEL Flat Com 40 is in the Woodwork Room.

  • Maximum Material Size: 1000mm x 700mm x 75mm

The Roland Mini Mill is a small test machine located in the 3D Print room

  • Maximum Material Size: 200mm x 150mm x 50mm


The CNC Routers are staff run by appointment. Bookings can be made by visiting the 3D workshop and talking to Roisin. When coming to book it is helpful to have a file ready to show the Technician. This will allow us to give you a more accurate timescale

When your file is ready the Technician will program the file through ArtCAM. ArtCAM is a software that tells the CNC router which tools to use, where to cut and other vital information.

Please allow enough plenty of time for CNC projects.

File Preperation

2D Files

  • 2D file must be vector or paths
  • Text must be outlined
  • Close Vectors and paths
  • At least 20mm between pieces and edge of material
  • You can prepare your files in any software but you must export is as .DXF

3D Files

  • Scale model to real life size
  • You can prepare your files in any software but you must export is as .STL
