Optimize CNC Cut Quality – FreeCAD CAM Tip 13 (Toolpath Finishing Guide)
Improve the quality of your CNC cuts! In this tutorial, you’ll learn how to refine your toolpaths, adjust machining parameters, and generate cleaner, smoother G-code for professional results.
This guide is useful for CNC beginners and machinists using any CAM software (I'm using FreeCAD 0.22 development version in this video) — the principles apply whether you’re using FreeCAD, Fusion 360, or other CAD/CAM solutions.
What you’ll learn:
How to reduce chatter and tool marks during CNC milling
Best finishing passes for pockets, profiles, contours, and rounded holes
Toolpath tricks for smoother edges and bottom surfaces, and higher-quality cuts
Step-by-step workflow for improving cut finish
