Tolerance recommendations

Tolerance control in sheet metal fabrication requires balancing functional needs with real manufacturing behavior. This article outlines practical tolerance ranges, DFM spacing rules, and industry-specific considerations to help reduce scrap, control cost, and achieve stable, repeatable production.

Tab-and-slot design tips

Tab-and-slot design is a proven DFM strategy in sheet metal fabrication that improves assembly alignment, reduces tolerance stack-up, and minimizes the need for fixtures.

Hole-to-edge and hole-to-bend distance

Proper hole placement is a critical DFM factor in sheet metal fabrication. Holes placed too close to bends or edges can distort, crack, or shift during forming, causing assembly and cosmetic issues. This article outlines practical hole-to-bend and hole-to-edge guidelines and shows how early DFM adjustments improve yield and production stability.

Design for Manufacturability (DFM)

Design for Manufacturability (DFM) is a critical discipline in precision sheet metal fabrication, bridging the gap between CAD design and real-world manufacturing.
