CNC Plasma in the Ag Shop: Complete Agricultural Mechanics Curriculum Bundle

📦 Instant digital download • Doc files • Licensed for classroom/personal use, not for resale

This complete CNC plasma curriculum bundle is designed for Agricultural Mechanics, Agricultural Equipment Design & Fabrication, and related CTE courses. The six-unit sequence guides students from basic CNC shop safety and equipment operation through software, first cuts, production teams, CAD design, project planning, business concepts, and an independent capstone project.

The curriculum was developed from a hands-on agricultural mechanics classroom model in which students learned the entire production process — from digital design and CNC setup to cutting, cleaning, fabrication, finishing, quality control, and customer-based production.

Lessons are designed for approximately 45–50 minute class periods and are organized into six six-week units. The progression intentionally moves students from highly guided instruction to increasingly independent, industry-style project work.

Suggested Closing

This bundle is designed for teachers who want students to do more than simply operate a CNC plasma table. Students learn how to design, manufacture, troubleshoot, improve, and manage real-world projects from start to finish.

The curriculum works especially well in Agricultural Equipment Design & Fabrication, Agricultural Mechanics, welding/fabrication, and other secondary CTE shop programs.

Created for hands-on, project-based agricultural mechanics classrooms.
