A component can be geometrically correct in CAD, yet still be prohibitively expensive or practically impossible to machine on the factory floor. We bridge design intent with manufacturing reality.
Once drawings reach the machine shop, minor oversights—like a 0.5mm internal corner radius requiring custom micro-tooling—multiply cycle times. DFM catches and resolves these before steel is cut.
Eliminate impossible sharp internal corners, standardize tool radii, minimize 5-axis setup repositioning, and prevent tool chatter on thin walls.
Ensure bend radii match standard tooling dies, maintain hole-to-edge relief distances, and optimize nesting to slash raw material scrap.
Audit draft angles (1° to 3°), maintain uniform wall thicknesses to prevent shrinkage voids, and optimize parting lines and core pull directions.
Standardize weld preps, verify torch access clearances, minimize distortion through symmetrical weld placement, and use standard structural sections.
Design for self-supporting angles (45°+ rule), hollow structures with escape holes, and topology optimization for metal and polymer AM.
Statistical and worst-case tolerance stack-up analysis. Loosen non-critical tolerances while locking critical mating fits (H7/g6, etc.).
Ingestion of nominal CAD solid geometry from client or internal design team.
Cross-examination against targeted shop floor processes (3-axis CNC, sand casting, laser cut).
Pinpoint unreachable cutter depths, stress risers, lack of draft, or extreme tolerance callouts.
Re-sculpt features with standard radii, draft tapers, and uniform wall transitions.
Calibrate GD&T to machine capability (CPK) rather than arbitrary tight default tolerances.
Issue clean, verified 2D drawing sets and CAM-ready neutral geometry.
