Mastering High-Precision Surface Finishing for Modular Prototypes: Lessons from the CNC Trenches
Achieving flawless surface finishes on modular prototypes demands more than just advanced machinery—it requires a deep understanding of material behavior, toolpath strategies, and post-processing finesse. In this article, I break down a real-world case where we achieved a **Ra 0.2µm finish** on a complex aluminum modular component, slashing rework by 40% through innovative tool selection and adaptive machining techniques.
