How to twist sheet metal to form an auger shape.

Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms. Read on as we show you some basic techniques you can use to reshape and shape your metals from the comfort of your own home with basic metal shaping handtools. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. I think an auger screw is going to fall into the second category.

Sheet metal forming is a costly manufacturing process that is widely used in different industries. This video describes how to use twist feature in solidworks. Other shapes such as a sphere will require actually stretching or compressing the plate in areas to form the shape. The feature is limited to only 2 profiles and no guide curves so look for opportunities to put most of the complexity into the profiles.

You won t know the exact shape to cut without some trial and error and it would depend on the forming process as well. By doing so the sheet can be bent or stretched into a variety of complex shapes. The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail. The average hack requires at least one angled metal part and the best tool to make one is still the good ol press brake.

Most highly complex shapes that are actually formed out of sheet metal can be created using lofted bends but often the trick to creating the shape lies in what you use for the profiles. If your sheet metal is long ask a friend to stabilize the part hanging out from the form blocks so it doesn t affect the bend.
