Engineering Sheet Metal Drawing Notes

The proper relation of views in a drawing.

Engineering sheet metal drawing notes.

Accuracy in the use of the scale rule. Drawing force power and number of stages defects in products. However in order to have a measure for sake of comparison the limit drawing ratio ldr is taken as a measure of drawability. Engineering drawing basic sheet layout title block notes engineering working drawings basics.

Bend notes are associated with a drawing view. Engineering graphics is used in the design process for visualization communication and documentation. A bend table lists propertied of all bends in a flat pattern view of a sheet metal part. Just before the punch contact work 2.

Fig shows the shearing of sheet metal between two cutting edges. Punch begins to push into work causing plastic deformation 3. Cutting of sheet metal is accomplished by a shearing action between two sharp edges. 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.

How to dimension a drawing. 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. Unit iv sheet metal working economical considerations stamping forming and other cold working processes. Bend tags associate rows in a bend table with the view geometry.

In making the layout for this cleat the following points must be kept in mind. Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect. After you insert the bend table in the drawing bend tags are added to the selected drawing view.
