What is DFM?
Design for Manufacturing is the process of designing parts and assemblies to reduce complexity, lower costs and make them easier to manufacture. Every drawing submitted to Metal Works is reviewed by an engineer for DFM.

Drawing Information
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Sheet Metal Tolerance Considerations (When dimensioning a part considerations for)
Forming (Bend Considerations)
Part Reductions with Special Features
Forming (Bend Considerations)
Part Combination, Symmetry and Common Thicknesses.
Design for Sheet Metal
Designing in common part thicknesses, Symmetry and combined features will enable parts to be nested together, reduce the number of parts and reduce assembly time. This helps reduce assembly cost.

10 Sheet Metal Parts
2 Different materials
2 Different setups
2 Different setups
6 Sheet Metal Parts

Forming (Bend Considerations)
Minimum Cuts, Flanges and Notches
Riveting and Alignment Features
Critical features within an assembly require Increased awareness. Alignment feature as in welding are a cost effective way to reduce assembly time and ensure critical dimensions are met.
