Introduction to CAD, CAM, and Practical CNC Machining for Milling

Get foundational knowledge in 3D modeling, toolpath programming, and practice use of CNC machining for milling.
Software used in this course:
  • Fusion 360

Overview

Future-proof your skills for today’s evolving industry. Manufacturing technology is more accessible than ever to startups and next generation entrepreneurs and makers. Now, more than ever, you can get your hands on the tools needed to design and make your ideas a reality.

Get foundational knowledge in computer-aided design (CAD), manufacturing, and the practical use of CNC machines for milling. Explore how to properly sketch and model 3D parts and CNC-machining basics, to ensure that you have the ground-level knowledge needed to effectively define toolpaths. Research the basics of setting up a CAM program and defining toolpaths to cut simple geometry. This basic process gets repeated for the design and manufacture of any part and is a critical step in learning and understanding the process.

After completing this course, you’ll be able to:

  • Explain the CAD design process, as applied to prismatic parts.
  • Summarize the workflow of digital manufacturing.
  • Demonstrate knowledge and skills in basic Fusion 360 CAM.
  • Recall foundational knowledge of practical CNC machining.
