Engineering Sheet Metal Drawing Notes

Bend tags associate rows in a bend table with the view geometry.

Engineering sheet metal drawing notes.

The proper relation of views in a drawing. Bend annotations a bend note adds fabricating information to sheet metal bend centerlines. 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. The shearing action is illustrated in the figure.

In making the layout for this cleat the following points must be kept in mind. After you insert the bend table in the drawing bend tags are added to the selected drawing view. 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.

Bend notes are associated with a drawing view. Accuracy in the use of the scale rule. Cutting of sheet metal is accomplished by a shearing action between two sharp edges. Punch begins to push into work causing plastic deformation 3.

Engineering graphics is used in the design process for visualization communication and documentation. Blanking and piercing bending and forming drawing and its types cup drawing and tube drawing coining hot and cold spinning. 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.

A bend table lists propertied of all bends in a flat pattern view of a sheet metal part. Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect. Drawing force power and number of stages defects in products.
