Design for manufacturability (DFM) means aligning geometry, tolerances, and material choices with how parts are actually fixtured, cut, deburred, and inspected. Good DFM reduces scrap risk, stabilizes cycle time, and avoids “impossible” blends of tolerance and access.
Examples include adding relief for internal corners, avoiding unnecessary deep pockets with small radii, and consolidating datum references so inspection matches fabrication.
A practical DFM review before cutting metal often pays for itself by preventing late-stage rework when assembly or coating processes reveal an unmachinable edge condition.
