In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger.
Design of sheet metal parts ppt.
A 1 degree tolerance on all bend angles.
Ppt on sheet metal process 1.
Designers and engineers develop components as small as washers and as large as entire roofs.
Design considerations for sheet metal parts.
If you design your sheet metal part as a solid object it s important that you send us a cad file that appears folded but shows where bends should go.
Therefore exceptions can be there for complex features design.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends.
Other sheet metal forming operations 5.
Sheet metal fabrication in china sheet metal is a kind of integrated metal cold working technology for metal sheet usually in under 6mm usually the parts plastically deformed by handwork or stamping die to form your desired shape and size and it also can be further formed more complex parts by welding or other metal cold working technology including laser cutting punching bending.
In this blog we are going to focus on sheet metal design considerations such as material selection wall thickness bend radii bend allowance.
Related to this because the raw materials are single sheets of metal the entire part must have the same material thickness throughout.
Sheet metal is one of the most versatile materials and processes in the world today.
