Design for manufacturability starts before a toolpath is programmed. Small changes to geometry, tolerances, wall thickness, and corner radii can reduce machining time and improve repeatability.
For CNC milling, engineers should avoid unnecessary deep pockets, specify realistic tolerances, use standard hole sizes where possible, and consider how the part will be fixtured.
Early DFM review helps reduce tool changes, scrap risk, and per-part cost while keeping the finished component aligned with functional requirements.
