In this class you’ll be introduced to BARN’s Computer Numerically Controlled (CNC) Plasma Cutter and its safe operation. Plasma is an ionized high temperature arc. The Plasma Cutter uses the plasma arc under directed air pressure to cut through metal sheet or plate. With this device you can cut patterns from mechanical drawings or images of art work. Just as in BARN’s other metal fab CNC machines, this system is based on the Centroid Acorn controller and has a similar user interface. G-code used to drive the machine can be generated by Fusion 360 from drawings or images, or you can make use of Centroid’s Interactive CoNversational (ICN) mode that lets you cut shapes defined by a sequence of cutting operations. 

This class complements our hand-held plasma cutter classes and focuses on safety, start up and shut down procedures, and cutting simple shapes using the Centroid’s Interactive CoNversational (ICN) mode.

“CNC Plasma Cutting and Fusion 360” (a next-step class in CNC Plasma sequence) will introduce you to creating and importing DXF and SVG files into Fusion 360, or making drawings in Fusion 360, and then use Fusion 360 to generate G-code for the plasma cutter.

Another next-step class, “Fusion 360 Sheet Metal Basics”, will introduce you to the sheet metal capabilities in Fusion 360 that can then be used to cut parts for sheet metal parts that will be bent and formed.
