CNC (Computer Numerically Controlled) machining is a process in which a digital program can be used to create accurate physical models based on CAD files. CNC machines are used to mill block and flat stock materials. CNC milling is also suitable for machining complex 3D contoured surface or solid models.

The Emily Carr University CNC area runs one 3-axis router model AXYZ 4008 from AXYZ International in Burlington, Ontario. The machine has unique abilities and limitations in regard to material type and size that need to be taken into account when preparing a model for CNC machining.

The CNC MachineThe AXYZ 4008 CNC router is located in room 178 (sculpture) area. It is capable of machining a wide range of materials in a reasonably large envelope. It has a carousel capable of holding 8 unique tools. All CNC programming for the AXYZ 4008 is currently done by the CNC technician. Tutorials for the AXYZ 4008 will be made available as standard tools and material settings are developed.

The AXYZ 4008 is best suited to mill sheet stock and other materials that are not too flexible. The bed of the AXYZ 4008 is commonly used with standard material sizes of 4' x 8' x 3.5". Thicker cuts can be obtained by "slicing" the model into layers with registration holes for assembly.
