On day one, you’ll learn the essentials of BARN’s CNC mill, tool library, and techniques for safe operation. We’ll cover CNC mill basics, beginning with details of the machine and understanding lathe motion on the X, Y, and Z axes. Also: selecting and establishing part-zeros, various tools, function, feeds, and speeds.

On the second day, we'll spend the morning learning Fusion 360's CAM (computer aided manufacturing) tools to generate G-code (the language that instructs the CNC machine what to do and where to do it). These skills are essential in machining complex parts beyond what one could achieve on a manual mill. After a lunch break, we’ll load a model created by one of the students into Fusion 360, examine and prove the CAM setup and G-code, cut some air, and then cut some metal.


If you have a model (Fusion .F3D, or .STEP files) you're interested in working from, please bring it on a thumb drive.


A $5 materials fee included in the cost of the class covers what is needed.
