CNC Milling an Aluminum Replacement Part | FreeCAD CAM & G-Code Toolpath Workflow
Learn how to model, generate toolpaths, export G-Code, and CNC mill an aluminum replacement part using FreeCAD. This video covers the complete CAD to CAM workflow for designing parts, creating toolpaths, and machining aluminum on your CNC machine.
What you’ll learn in this tutorial:
Creating and dimensioning a 3D model of an aluminum replacement part
Sketching holes, positioning with constraints, and making through pockets
Adding bevels around holes for proper finishing
Setting up a new CNC job – toolbit selection, feeds & speeds for aluminum
Helix operations for cutting holes with optimized parameters
3D surface operations for beveled edges and outline profiling
Exporting and splitting G-Code files for safer CNC milling
Final CNC machining results of the aluminum replacement part
