Slotted Wheel CNC Tutorial | Design & G-Code Workflow in FreeCAD (CAD + CAM Toolpaths)
Learn how to design, program, and mill a slotted wheel from start to finish using FreeCAD’s CAM Workbench.
In this project-based tutorial, you’ll go step by step through the CAD modeling, CAM setup, and toolpath generation needed to machine a real slotted wheel with accurate slots and pockets.
You’ll see how to:
Model a wheel with slotted cutouts using sketches and polar arrays
Add construction geometry to fix toolpath generation issues
Create multiple CNC jobs for precise operations
Use pocket and profile operations
Export clean, ready-to-run G-code for your CNC router or mill
This video is perfect for CNC hobbyists, makers, and machinists who want to understand how to handle complex geometries in FreeCAD CAM.
