Welcome to 3D CAM! In this class, you will learn Computer Aided Manufacturing (CAM) skills for 3D surfacing using Fusion 360. Fusion 360 is software that can be used both for design (CAD) and manufacturing. After following step-by-step instructions to create 3D toolpaths for a wooden serving spoon, you will learn how to machine it on a CNC router.

This class requires no previous experience with 3D toolpathing. However, you should have an understanding of CNC fundamentals and 2D CAM. Check out our CNC class and 2D CAD and CAM class to learn more. Although in this class we will be programming toolpaths specifically for a DMS router, what you will learn about machining strategy and 3D CAM will still apply to other CNC routers.

Julie Kumar is the CNC Lead at Autodesk's Pier 9. She guides new CNC users through a unique training program called the CNC Learning Path, in which new users are introduced to CNC concepts, CAM programming, and CNC machining through a series of classes, skill checks, and hands-on exercises. She also teaches machine operation for cutting-edge CNC equipment, including the Haas Mill, DMS 5-axis router, and Matsuura 5-axis Mill. Her background is in sculpture and installation art, so she brings a unique, interdisciplinary approach to the world of programming and subtractive manufacturing.
