Engineering Sheet Metal Drawing Notes

How to dimension a drawing.

Engineering sheet metal drawing notes.

Blanking and piercing bending and forming drawing and its types cup drawing and tube drawing coining hot and cold spinning. Punch begins to push into work causing plastic deformation 3. In making the layout for this cleat the following points must be kept in mind. Just before the punch contact work 2.

However in order to have a measure for sake of comparison the limit drawing ratio ldr is taken as a measure of drawability. 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. After you insert the bend table in the drawing bend tags are added to the selected drawing view. Bend notes are associated with a drawing view.

Accuracy in the use of the scale rule. Fig shows the shearing of sheet metal between two cutting edges. Unit iv sheet metal working economical considerations stamping forming and other cold working processes. Engineering drawing basic sheet layout title block notes engineering working drawings basics.

The proper relation of views in a drawing. A bend table lists propertied of all bends in a flat pattern view of a sheet metal part. Engineering graphics is used in the design process for visualization communication and documentation. 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.

The shearing action is illustrated in the figure. Drawing force power and number of stages defects in products. Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect.
