CNC Milling

Computer Numerical Controller (CNC) Milling is a machining process which utilizes rotary cutters in order to remove material. Similar to drilling and cutting machines, milling allows the user to achieve many of the same operations. However, the CNC Mill is able to move along multiple axes, thus creating different shapes unable to be obtain readily on conventional drilling and cutting machines.
Essentially, any material that can be cut and/or drilled can be machined by a CNC Mill. However, most of the work performed on the machines used at Rutgers Makerspace is in wood and MDF.

FAQs

What is CNC milling?

Computer Numerical Controlled (CNC) milling is a machining process that utilizes both drilling and cutting in order to achieve the complex shapes desired in the part file. The computer analyzes the G-code and moves the drill bit along different axes, in order to make various shapes and holes.

How do we use the CNC mill?

First, you need to use an appropriate CAD software in order to design the 2D/3D image and save the file accordingly either as a .dxf or .stl respectively. Then some post-processing has to be done to get the correct .CAM and toolpaths built. Finally, contact a member of the Makerspace staff in order to setup your material and finish the design.
