CNC Milling

CNC Milling

CNC machine stands for computer numerically controlled machine, which means these tools have the ability to cut select materials with extreme precision using router bits. This process is one of the most complex ways of working within the digital fabrication shop and requires the most attention to detail. It is recommended to schedule a consultation with a shop technician before selecting this process for your project. For inquiries please email vpashops@syr.edu. Models can take from 1-36 hours to create, depending on the complexity, size of the model, the type of material being milled, and the type of finish requested. Only one mill job can be run at a time; therefore, students should plan to queue their files several days in advance of deadlines. During peak times, the wait can be more than a week.

CNC Machine Types


 The VPA shops has two CNC machines across our digital fabrication department. These machines are intended for wood, foam, and plastics. Before committing to which machine you like to work with read through the following machine specs to get an idea as to which one is right for your project.
 

48x96 Techno CNC Machine


 The Techno CNC can process hardwoods, softwoods, dense foams, and plastic sheets. The maximum material size for this machine is 96inx48inx4in. The quality and duration of the job depends on the type of router bits and type of milling job. For a more accurate quote, contact the digital shop technician. This machine is located in the Warehouse.
 
** This machine has a minimum cutting fee of $15.00 this includes 30 minutes of cutting and 30 minutes of file setup. After the initial 30 minutes, cut time and file preparation accumulate at a rate of $0.25 a minute.**
 

48x96 Shopbot CNC Machine with Indexer


The Shopbot CNC with indexer can process hardwoods, softwoods, dense foams, and plastic sheets. The maximum material size for this machine is 48inx96inx4in. The quality and duration of the job depends on the type of router bits and type of milling job. This is a self service machine during open shop hours. To learn file set up and operation please inquire at vpashops@syr.edu. Learning to use this equipment will take multiple sessions. Please plan accordingly.

The ShopBot 12" Rotary Indexer adds a fourth axis to the CNC router, allowing users to machine round and cylindrical objects from multiple angles. It expands projects beyond flat-sheet cutting into things like table legs, columns, handles, spindles, reliefs, and other 3D forms. Users should first become comfortable with flat milling.
 
** There are no costs to use this equipment. Users are responsible for file set up, monitoring the machine during cuts, providing material and any specialty bits.** 
 

Material Usage

  • All materials used for CNC Milling must be checked by a technician on staff before loading the material on to the machine.

  • Severely bent, warped, or damaged material will not be allowed on any CNC machine. Cabinet grade plywood or better is required.

  • All unknown materials will require the submission of a material safety data sheet.

  • Most woods, foams, and plastics are CNC compatible.

  • Students can supply their own materials or buy them directly from the shop through Papercut. Material purchasing is available at the Warehouse shop only.

  • Before making any material purchases check with a technician on staff if the material you would like to use is compatible with the process.

  • Denser materials take longer to machine. Keep this in mind when planning for a project.

File Submission For CNC Milling/Cutting 

  • 3dm. files are the preferred method for the file submission process, however we will accept; AI. Files, DXF. Files, and DWG. Files. Keep in mind the longer it takes a technician to process the file the longer it will take to begin running it.

  • For CNC cuts at the Warehouse, submit your file through the File Submission link. Specify which your desired resolution, what type of stock you are cutting, and if you are buying the stock directly from the shop or supplying it yourself.

  • If you plan to supply your own material, it needs to be dropped off before we can digitally process the file.

  • Plan to schedule a consultation with a digital technician to ensure the cut is processed exactly how you intend it to be.
