Engineering Sheet Metal Drawing Notes

Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect.

Engineering sheet metal drawing notes.

Engineering graphics is used in the design process for visualization communication and documentation. The shearing action is illustrated in the figure. How to dimension a drawing. Bend notes are associated with a drawing view.

The proper relation of views in a drawing. Drawing force power and number of stages defects in products. Accuracy in the use of the scale rule. A bend table lists propertied of all bends in a flat pattern view of a sheet metal part.

In making the layout for this cleat the following points must be kept in mind. However in order to have a measure for sake of comparison the limit drawing ratio ldr is taken as a measure of drawability. Just before the punch contact work 2. The sheet metal cleat the work of this problem will consist in laying out to full size the views and pattern for a galvanized sheet metal cleat.

Engineering drawing basic sheet layout title block notes engineering working drawings basics. Engineering graphics is an effective way of communicating technical ideas and it is an essential tool in engineering design where most of the design process is graphically based. After you insert the bend table in the drawing bend tags are added to the selected drawing view. Bend tags associate rows in a bend table with the view geometry.

Bend annotations a bend note adds fabricating information to sheet metal bend centerlines. Punch begins to push into work causing plastic deformation 3. Blanking and piercing bending and forming drawing and its types cup drawing and tube drawing coining hot and cold spinning.
