Introduction to CAD, CAM, and Practical CNC Machining

This course introduces you to foundational knowledge in computer-aided design (CAD), manufacture, and the practical use of CNC machines. We begin with the basics of Autodesk® Fusion 360™ CAD by learning how to properly sketch and model 3D parts. Before we program any toolpaths, we’ll explore CNC machining basics to ensure we have the foundational knowledge needed to effectively define toolpaths. Finally, we explore the basics of setting up a CAM program and defining toolpaths to cut simple geometry. This is the same basic process that gets repeated for the design and manufacture of any part and is a critical step in learning and understanding the process.

  • 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.

Steve, when you duplicate the roughing operation and turn it into a rest operation with the 3/8in tool, are the tool settings matching? 0.5in roughing tool with a 0.0 corner radius? When you manipulate that corner radius value it changes how the toolpath is calculated. In the rest machining pockets lesson the intention is to show how an adaptive toolpath isn't the best option to use for finishing. Make sure your roughing toolpath is edited to leave stock only on the walls, then created a 2d contour to finish the pocket. If you want to play around with the adaptive please let me know what spot in the process(since we edit it a few times) produced any results. For example did the initial duplication and edit work but the second change fail?
On the two finishing operations, I get a warning stating, "Skipping a pocket since the rest tool has not removed any material." Not sure why I get the error. I think I have matched all the settings. Any ideas?
Good
