Rake Face: What It Is and Why It Matters in machining
This article explains what the rake face is in machining and why it matters for CNC cutting performance. It covers the rake face location, its relationship with rake angle, positive, negative, and neutral rake designs, and how this surface affects chip flow, cutting force, heat, tool wear, tool life, surface finish, and machining stability. It also outlines common rake face problems and practical selection principles based on material, operation, and machine rigidity.
