CNC Plasma Cutting Workshop

This hands-on workshop covers the essentials of CNC plasma cutting, from safety, file processing to machine operation.

Learn the essentials of CNC plasma cutting in this hands-on workshop. Participants will be introduced to machine safety, how to set up vector files, and the workflow from digital file to finished cut. Each student will cut a basic design, gaining practical experience in setup, operation, and post-processing.

Part 1 - Introduction and Safety.

• What a CNC plasma cutter is and what it can do.
• Overview of the machine components (torch, gantry, controller, compressor).
• Safety briefing: PPE, welding screens, ventilation precautions, fire safety
• Demonstration of safe machine startup.

Part 2 - Understanding Software and Designs.

• Quick intro to vector design for plasma cutting 
• Key design rules: closed shapes, no overlapping lines, accounting for kerf.
• Understand differences between DXF/SVG file formats.
• Importing files into SheetCAM.
• Setup up workflows, cutting a single part to multiple.
• Generating toolpaths and gcode.

Part 3 - Hands On Cutting.

• Basic machine operations.
• Importing gcode and setting voltage and amperage
• Zeroing out machine on workpiece.
• The instructor demonstrates cutting sheet metal.
• Each student runs the machine under supervision.
