Engineering Sheet Metal Drawing

Sheet metal drawing as you may have guessed sheet metal drawing is used to produce sheet metal.

Engineering sheet metal drawing. Sheet metal while a strong and durable material has structural limitations on what it can do. Including an isometric view on the drawing is one of them see figure 2. By this is meant that the materials dealt with are usually in the form fig 1 pictorial representation of anvil. This makes it easier to see where the bends in the sheet metal start.

While pressure is applied to the blank the drawing machine stretches the metal to the desired size and shape. Deep drawing is often more cost effective than spinning when the run quantity is very large and a high production rate is required. Nonetheless i have some good habits in creating drawings for sheet metal parts. Note that the isometric view has no hidden lines visible and that the tangent edges are visible.

Deep drawing is a process for forming sheet metal between an edge opposing punch and a die draw ring to produce a cup cone box or shell shaped part. When creating sheet metal drawings designers have to think about the limitations of the metal material and how it can be molded into different shapes for product designs. Sheet metal drafting is merely the application of the principles of ordinary mechanical drawing to objects which for the purposes of drawing lack thickness.
